Please only give a ONE answer.
i said/asked calmly
Answers
The statement that describes an attribute of an artesian well is B. Uses natural pressure.
Artesian wells rely on natural pressure by accessing an underground water source that is enclosed between layers of impermeable rock or clay. The water within the aquifer is naturally pressurized due to the weight of the overlying rock or the slope of the land.
When a well is drilled into the aquifer, this existing pressure allows the water to rise to the surface without the need for a mechanical pump.
This utilization of natural pressure distinguishes artesian wells from other types of wells, as they do not require artificial pumping mechanisms to extract water.

Which human activity contributes to the formation of acid rain
Answers
(C) burning fossil fuels such as coal and gasoline.
It also contributes to the formation of smog.
Burning fossil fuels such as coal and gasoline
We know that burning fossil fuels, such as coal and gasoline, is a significant human activity that contributes to the formation of acid rain.
When fossil fuels are burned, they release pollutants into the atmosphere, including sulfur dioxide (SO2) and nitrogen oxides (NOx).
These pollutants can react with water, oxygen, and other chemicals in the atmosphere to form sulfuric acid (H2SO4) and nitric acid (HNO3), which are major components of acid rain.
Therefore the correct answer is

A small gap is left between the rails in the railway track. Analyze the reason.
Answers
Answer:
There could be several possible reasons for a small gap between rails on a railway track, such as:
1. Expansion joints: Railways are designed to allow the tracks to expand and contract with changes in temperature. To accommodate this expansion, small gaps are left between the rail ends and filled with expansion joints or plates.
2. Wear and tear: Over time, the rails may experience wear and tear due to heavy loads, weather conditions, and other factors. As a result, small gaps can appear between the rails.
3. Maintenance: During maintenance activities, rail tracks may be adjusted or replaced, which could lead to small gaps between the rails.
4. Environmental factors: Environmental factors such as soil shifts, earthquakes or other natural disasters can also affect the alignment of the rails, leading to small gaps.
These are some of the possible reasons for a small gap between the rails on a railway track.
Answer:
The small gap left between the rails in a railway track is intentional and serves a specific purpose. This gap is known as the rail joint, and it allows for the expansion and contraction of the rails due to changes in temperature. When the temperature changes, the metal rails will expand or contract, and if they were joined together tightly, they could buckle or become deformed, which could be dangerous for trains passing over them. The rail joint allows the rails to move slightly and prevent damage to the track.
Additionally, the rail joint also allows for maintenance and repairs of the track. If there were no gap between the rails, it would be challenging to replace a damaged rail or perform routine maintenance, such as tightening bolts or lubricating joints. With the rail joint, maintenance personnel can easily access and work on the track.
Overall, the small gap left between the rails in a railway track is intentional and serves a crucial function in ensuring the safety and reliability of the track.

This graduated cylinder has numbers representing milliliters. A student says that the volume of the liquid inside is 21.8 milliliters.
What best explains why the student is wrong?
21.8 is at the top of the meniscus, but volume should be measured in the middle of the meniscus.
21.8 is at the top of the meniscus, but volume should be measured at the bottom of the meniscus.
Since the lines are only marked with whole numbers, the student must round to a whole number.
Since the whole numbers represent milliliters, the student must use a unit smaller than milliliters.
Answers
Answer:
The answer for this question depends on the type of meniscus in the cylinder. If it is an upright meniscus like in water, the reading should be taken at the bottom of the meniscus. However if it is an inverted meniscus like in mercury, the reading should be taken at the top of the meniscus.

During which phase change will two grams of water
release 668 joules of heat energy?
A. melting
B.
freezing
C.
vaporization
D. condensation
Answers
During the phase change of 2 grams water to solid-state, there has been the release of energy, and the process will be freezing. Thus option B is correct.
The release of the amount of heat by the sample has been able to change the state of the matter from the loosely bounded to the combat state.
The melting has been the process of conversion of solid-state to a liquid state. In the process, there has been the absorption of the energy for the rupture of the bond.The freezing has been the conversion of liquid state to solid-state. The process requires a little amount of energy for the conversion.The vaporization requires the absorption of energy and converts the liquid state to the vapor state.The condensation has been the process of conversion of the vapor to the gaseous state. The process releases energy in large amounts.Thus, during the phase change of 2 grams water to solid-state, there has been the release of energy, and the process will be freezing. Thus option B is correct.

Are there any steps of the rock cycle that do NOT connect directly to one another? Explain why this may be the case using at least two examples.
please helpp
Answers
Answer:
rocks are destroyed
explanation
ricks are never destroyed they descompose
There are no steps in the rock cycle that do not connect directly to one another. The rock cycle describes the continuous process by which rocks are formed, weathered, eroded, transported, deposited, and lithified, leading to the formation of new rocks.
What are the steps in rock cycle ?Each step of the rock cycle is interconnected and depends on the other steps. For example, the formation of sedimentary rocks requires the weathering and erosion of preexisting rocks, the transportation and deposition of the resulting sediments, and the lithification of the sediments into rock.
Without the weathering and erosion of preexisting rocks, there would be no sediment to form sedimentary rocks.
Similarly, the formation of metamorphic rocks requires the heat and pressure of burial and tectonic activity, which in turn is influenced by the existing rock formations and geological processes of the area.
Another example is the formation of igneous rocks, which can occur through the melting and solidification of preexisting rocks, or through volcanic activity.
