According to the passage, carbon dioxide is the most abundant greenhouse gas on Earth. What is the leading cause of Carbon Dioxide rising in the last 100 years?
Answer the question using the CER strategy. Be sure to use evidence from source 1 and 2.
Answers
Answer:
Human activities, especially the burning of fossil fuels like coal, oil, and natural gas, are primarily to blame for the rise in carbon dioxide levels over the past 100 years. Carbon dioxide is produced as a byproduct of combustion when these fossil fuels are burned for transportation, industrial processes, energy production, and other uses. Together with other greenhouse gases, this human-caused release of carbon dioxide has significantly boosted atmospheric carbon dioxide concentrations, causing the greenhouse effect and amplification of global warming and climate change.

Which of the following does not describe an ecosystem in a state of dynamic equilibrium?
A An ecosystem that is constantly changing
B An equilibrium that becomes unbalanced.
C An ecosystem that can return to a balanced state.
D An ecosystem that can respond to disruptions.
Answers
An ecosystem that is constantly changing is not in a state of dynamic equilibrium.
A state of dynamic equilibrium is a state in which an ecosystem is relatively balanced. The ecosystem may be com unbalanced by by natural changes but returns to its original state. An ecosystem in a state of dynamic equilibrium remains unchanged for a long time.
Hence, an ecosystem that is consistently changing is not in a state of dynamic equilibrium because dynamic equilibrium has to do with relative stability of an ecosystem.

How does the sport curling relate to Newton’s Second Law of Motion?
Answers
Curling is a sport in which players slide stones across a distance of ice toward a target area. The purpose is to accumulate the loftiest score for a game by making monuments rest closest to the center of the target at the end of each side. There are two brigades. Each platoon is trying to keep the other platoon's monuments down from the target by knocking their monuments out of the way.
Newton's Second Law " The acceleration of an object is directly commensurable to the net force acting on it and is equally commensurable to its mass. The direction of the acceleration is in the same direction as the net force acting on an object." This relates to the formula F = ma. The mass of the determinedness monuments in curling is 38 to 44 pounds or 17.3 to 20 kg. The thing of the sweepers is to control the acceleration of the gravestone by reducing disunion on the ice, which affects the force with which the gravestone is suitable to impact the other monuments.

https://brainly.com/question/25545050
Second law-
Newtons second law occurs during curling when the delivery man, such as Glenn Howard, applies force to the stone pushing down the lane to the target while friction pulls it back the other way to a slow stop. The mass of the stone is 40lbs and the net force of everything on item will give you its slowly decreasing acceleration. Otherwise known as, F=mA.
Third law-
This law can be exerted in the sport of curling when the force behind a stone being delivered is transferred into another stone that is at rest, where the energy and force of one moving object is transferred to another. This almost completely stops the original stone, and gives some speed to the stone(s) it collides with.

I need to explain the electromagnetic spectrum to fifth graders.
Answers
Answer:
Explanation:
The electromagnetic spectrum is the range of frequencies (the spectrum) of electromagnetic radiation and their respective wavelengths and photon energies.
The electromagnetic spectrum covers electromagnetic waves with frequencies ranging from below one hertz to above 1025 hertz, corresponding to wavelengths from thousands of kilometers down to a fraction of the size of an atomic nucleus. This frequency range is divided into separate bands, and the electromagnetic waves within each frequency band are called by different names; beginning at the low frequency (long wavelength) end of the spectrum these are: radio waves, microwaves, infrared, visible light, ultraviolet, X-rays, and gamma rays at the high-frequency (short wavelength) end. The electromagnetic waves in each of these bands have different characteristics, such as how they are produced, how they interact with matter, and their practical applications. There is no known limit for long and short wavelengths. Extreme ultraviolet, soft X-rays, hard X-rays and gamma rays are classified as ionizing radiation because their photons have enough energy to ionize atoms, causing chemical reactions. Exposure to ionizing radiation can be a health hazard, causing radiation sickness, DNA damage and cancer. Radiation of visible light and longer wavelengths are classified as nonionizing radiation because they have insufficient energy to cause these effects.
Throughout most of the electromagnetic spectrum, spectroscopy can be used to separate waves of different frequencies, producing a spectrum of the constituent frequencies. Spectroscopy is used to study the interactions of electromagnetic waves with matter.[4]
Here are a few examples of the types of energy found in the electromagnetic spectrum:
Radio Waves - Radio waves are the longest type of energy in the electromagnetic spectrum. They are used to send signals for things like TV and radio shows.
Microwaves - Microwaves are shorter than radio waves and are used for things like cooking food in a microwave oven and sending signals for cell phones.
Infrared - Infrared is the type of energy that makes you feel warm when you are in the sun. It's also used to control your TV remote.
Visible Light - This is the type of energy that you can see! It includes all the colors of the rainbow - red, orange, yellow, green, blue, indigo, and violet.
Ultraviolet - Ultraviolet is the type of energy that makes your skin tan. It's also what makes a black light glow.
X-rays - X-rays are a type of energy that can go through your skin and show what's inside your body. Doctors use x-rays to see broken bones.
Gamma Rays - Gamma rays are the shortest type of energy in the electromagnetic spectrum. They are very powerful and are used in medicine to treat cancer.
So, that's the electromagnetic spectrum in a nutshell! It's a range of different types of energy that we use every day in many different ways.

As radiation from the sun reaches the earth, the energy is-
A ) Immediately radiated back into space.
B ) Absorbed by only the oceans
C ) Radiated, reflected, and absorbed
D ) Only reflected by clouds in the atmosphere
Answers
Answer:C
Explanation:All of the energy from the Sun that reaches the Earth arrives as solar radiation, part of a large collection of energy called the electromagnetic radiation spectrum. Solar radiation includes visible light, ultraviolet light, infrared, radio waves, X-rays, and gamma rays. Radiation is one way to transfer heat.
Answer: A) The amount of heat radiated from the atmosphere to the surface (sometimes called “back radiation”) is equivalent to 100 percent of the incoming solar energy.
B)On its northward journey, the water at the surface absorbs gases like carbon dioxide and chlorofluorocarbons (CFCs) – the latter are, to a large extent, the gases responsible for the ozone hole over Antarctica – as well as excess heat from the atmosphere
C)Water droplets and ice crystals that make up clouds scatter light equally at all wavelengths and therefore appear white. Reflection of solar radiation occurs when the radiation is sent directly backward from a surface. The fraction (or percentage) of radiation reflected back is known as albedo.
D)Clouds cool Earth's surface by reflecting incoming sunlight. ... Clouds warm or cool Earth's atmosphere by absorbing heat emitted from the surface and radiating it to space. Clouds warm and dry Earth's atmosphere and supply water to the surface by forming precipitation

A student is playing with marbles. He rolls a purple marble, which strikes a green marble that is at rest. After the collision, the green marble rolls away from the student. The purple marble rolls back toward him.
Why does the purple marble roll back toward the student? Explain your response in terms of Newton’s third law.
Answers
Answer:YOUR MOM LOL
Explanation: THIS IS THE ANSWER... NO FATHER LOL
Newton's third law states that every action has an equal and opposite reaction.
In the context of the scenario with the marbles, when the purple marble strikes the green marble, the green marble exerts an equal and opposite force toward the purple marble, which is why it rolls back toward him.
Transfer of momentum takes place from the green marble back to the purple marble. This can be explained in terms of Newton's third law, because the forces between two marbles are equal and opposite in direction.

3. Since photosynthesis is the primary source of oxygen in the atmosphere, it is vital to living organisms. Photosynthesis is the process by which green plants and trees produce food from sunlight, carbon dioxide, and water in the atmosphere: it is their primary source of energy.
4. Decomposers break down dead plants and animals and return nutrients to the soil. Carnivores get their nutrition by eating other species. Herbivores obtain their energy from the plants they consume. Plant and animal forms of nutrition are used by omnivores.
5. Energy is required for all living organisms to develop and reproduce, sustain their structures, and react to their surroundings. Metabolism is a series of life-sustaining chemical processes that enable organisms to convert chemical energy stored in molecules into energy for cellular processes.
6. Organisms compete for resources such as air, water, food, and space in order to live. In areas where these are sufficient, organisms coexist peacefully, and in areas where resources are plentiful, the ecosystem boasts a diverse range of species (diversity).
7. The word "niche" is used in ecology to describe the role that an organism plays in a group. The physical and environmental conditions that a species needs (such as temperature or terrain) as well as the relationships it has with other species make up a species' niche (like predation or competition).
8. Prey animals are species that serve as food for predatory animals. Many predators could end up as food for larger predators. The top predator is a predator species that does not prey on other animals.

Answer the following questions in the essay box below.
Why does the coil keep spinning?
Which way is electricity flowing?
Answers
Answer:
The coil keeps spinning because of the interaction between the magnetic field generated by the flow of electricity in the coil and the magnetic field of the permanent magnet surrounding it. This interaction creates a force that causes the coil to rotate continuously.
As for the direction of the electricity flow, it depends on the design of the coil and the direction of the magnetic field. If the coil is connected to a direct current (DC) source, the electricity will flow in a single direction. If the coil is connected to an alternating current (AC) source, the direction of the electricity flow will change periodically, typically many times per second.
In general, the direction of the electricity flow can be determined using Faraday's law of electromagnetic induction, which states that a changing magnetic field will induce an electromotive force (EMF) in a conductor, which will cause electricity to flow in the conductor. The direction of the induced EMF and the resulting electricity flow will depend on the direction of the changing magnetic field and the direction of the coil.
Explanation:
Answer:
The inertia of the rotating coil carries it through half of a turn, past the insulating paint. When the electric current starts to flow again, the twisting force is in the same direction as it was before. The coil continues to rotate in the same direction.
The permanent magnets exert forces on the electrical currents flowing through the loop of wire.
