B.
When air pressure increases over time at the location
C.
When two high pressure systems meet at the location
D.

Answers
Answer:
I would say C
Explanation:
Where warm moist air is forced to rise by hills, mountains, or areas where warm/cold or wet/dry air bump together, thunderstorms can form. The surface direction of wind varies depending on your location (northern/southern hemisphere, and even coastal/plains/mountains), and what weather patterns usually affect the area.
Thunderstorms can develop in situations where warm, moist air is compelled to ascend by hills, mountains, or places where warm, cold, or wet/dry air collide.
What is Thunderstorms?A thunderstorm is a downpour of rain accompanied by thunder. Since lightning produces thunder, all thunderstorms contain lightning.
Thunderstorms can happen at any time of the year, although they are more likely to happen in the spring and summer, especially in the late afternoon and evening.
Most thunderstorms happen in the late afternoon around the Gulf Coast and in the southeast and western states. The Plains states commonly see thunderstorms in the late afternoon and at night.
Therefore, Thunderstorms can develop in situations where warm, moist air is compelled to ascend by hills, mountains, or places where warm, cold, or wet/dry air collide.

Environmental Pollution occurs in different forms; air, water, soil, radioactive, noise, heat/ thermal, and light
Air Pollution
Water Pollution
Soil pollution
Noise pollution
Radioactive pollution
Light pollution
Humans are the main cause of water pollution, which is triggered in many ways: by the dumping of industrial waste; due to temperature rise, that cause the alteration of water by reducing the oxygen in its composition; Or due to deforestation, which causes sediments and bacteria to appear under the soil
Most of this air pollution we cause results from the burning of fossil fuels, such as coal, oil, natural gas, and gasoline to produce electricity and power our vehicles. Carbon dioxide (CO2) is a good indicator of how much fossil fuel is burned and how much of other pollutants are emitted as a result.
Effects:
Nutrient pollution can cause toxic algal blooms in drinking water sources that create toxins that kill fish and other aquatic animals. Direct exposure to this toxic alga causes serious health problems in humans including neurological effects, respiratory problems, stomach and liver illness, and rashes.
answer 2:
The Industrial Revolution brought rapid urbanization or the movement of people to cities. Changes in farming, soaring population growth, and an ever-increasing demand for workers led masses of people to migrate from farms to cities. Almost overnight, small towns around coal or iron mines mushroomed into cities.

Air pollution is a result of industrial and certain domestic activity. An ever increasing use of fossil fuels in power plants, industries, transportation, mining, construction of buildings, stone quarries has led to air pollution.
Main causes of air pollution
Particulate pollutants
Particulate matter suspended in air are dust and soot released from the industrial chimneys. Their size ranges from 0.001 to 500 µm in diameter. Particles less than 10µm float and move freely with the air current. Particles which are more than 10µm in diameter settle down. Particles less than 0.02 µm form persisent aerosols. Major source of SPM (suspended particulate matter) are vehicles, power plants, construction activities, oil refinery, railway yard, market place, industries, etc.
Water pollution
Water pollution is one of the most serious environmental problems. Water pollution is caused by a variety of human activities such as industrial, agricultural and domestic. Agricultural run-off laden with excess fertilizers and pesticides, industrial effluents with toxic substances and sewage water with human and animal wastes pollute our water thoroughly. Natural sources of pollution of water are soil erosion, leaching of minerals from rocks and decaying of organic matter. Rivers, lakes, seas, oceans, estuaries and ground water sources may be polluted by point or non-point sources.
Main causes of water pollution
Pesticides like DDT and others used in agriculture may contaminate water bodies. Aquatic organisms take up pesticides from water get into the food chain (aquatic in this case) and move up the food chain. At higher trophic level they get concentrated and may reach the upper end of the food chain.
2) The Industrial Revolution brought rapid urbanization or the movement of people to cities. Changes in farming, soaring population growth, and an ever-increasing demand for workers led masses of people to migrate from farms to cities. Almost overnight, small towns around coal or iron mines mushroomed into cities..
3) Benefits of Renewable Energy
Generating energy that produces no greenhouse gas emissions from fossil fuels and reduces some types of air pollution. Diversifying energy supply and reducing dependence on imported fuels. Creating economic development and jobs in manufacturing, installation, and more.
Disadvantages of Renewable Energy
Renewable Energy Is Not Available Round the Clock. ...
The Efficiency of Renewable Technologies Is Low. ...
The Initial Cost of Renewable Energy Is High.
4) Hazardous waste can be treated by chemical, thermal, biological, and physical methods. Chemical methods include ion exchange, precipitation, oxidation and reduction, and neutralization.
5) recycling = build an eco brick
reusing = reuse plastic bags
reduce. = close the water while brushing your teeth.

Grass is one of these. You can see that the grasshopper and rabbit eat the grass and the bird and the shrew eat the grasshopper. Imagine that there was a big increase in the number of snakes in this area. We would then expect the Response area numbers to drop. In this food web, we consider the hawk a Response area. If the hawk population increases, we would see a drop in birds and shrews and snakes! The fungi and bacteria in the food web are examples of Response area. They break down any and all dead organisms.

Answers
Answer:
1. Kingdom Protista
2. Kingdom Eubacteria
3. Kingdom Archaeabacteria
Explanation:
1. Kingdom Protista is one of the the six kingdoms. It consists of organisms called PROTISTS that are eukaryotic i.e. possess a membrane-bound nucleus and mostly single-celled (unicellular). Protists are eukaryotic organisms like plants, animals and fungi but their characteristics do not fit into any of these three eukaryptic groups. Protists include; algae, amoeba, etc.
2. Kingdom Eubacteria, as their name implies, are known as true bacteria. The constituent organisms of this kingdom are prokaryotic i.e. lack a membrane-bound nucleus and single-celled (unicellular). They possess a cell wall, in addition to their cell membrane, that is made up of PEPTIDOGLYCAN. Examples of organisms in this kingdom are Streptococcus, Bacillus etc.
3. Kingdom Archaebacteria were once grouped together with the true bacteria as kingdom Monera but were split because of their obvious differing characteristics. Archeans are single-celled prokaryotic organisms characterized majorly by their ability to live and thrive in extreme environmental conditions e.g hot conditions, anoxia conditions (no oxygen).

The picture shows a Single-celled organism that has a nucleus and organelles, lacks a cell wall, and obtains food by eating other organisms. The organism also has cilia that it uses to move through water. Which kingdom should this organism be classified?
Science
Answers
Protista
Protists are single-celled and usually move by cilia, flagella, or by amoeboid mechanisms. There is usually no cell wall, although some forms may have a cell wall. They have organelles including a nucleus and may have chloroplasts, so some will be green and others won't be. They are small, although many are big enough to be recognized in a dissecting microscope or even with a magnifying glass. Nutrients are acquired by photosynthesis, ingestion of other organisms, or both.

The global population has increased immensely over the last two centuries. Humans use fossil fuels to do a variety of tasks from heating their homes to travel to production of everyday products. As the human population has increased, so have the global fossil carbon emissions.
Write a scientific explanation that describes total world carbon emissions in 2050 if the world’s population decreases to five billion people.
Claim:
Evidence:
Reasoning:
Answers
Answer:
The earth would eventually become become a brown and grey wasteland and the blue sky and rainbows and things like that will be rare rain would be highly acidic
Evidence: There are less people which means less cars will be driven less oil will be used etc. also fossil fuels are non renewable resource which means fossil fuels will be harder to find overall diving up prices of gas,heating,etc which might make Deter people from using fossil fuels and switching to something cheaper. At this point to people will dislike fossil fuels more then now.
Reasoning: I think people won’t like fossil fuels for 2 good reasons. First the driven up price. Second there will be noticeable effects from fossil fuels it 2050. It can make crops harder to grow which could lead to famine and a Recession because driven up food prices and it will hurt the economy. Towns will slowly flood. Arctic species will die so on. So a poor family’s that can’t afford food won’t spend more money on something that overall hurts them. They will despise people who use fossil fuels and it will become socially wrong. Civilization at that time might also be working on them self. Population decreased a major amount. Something bad happened. And if what ever caused the decline in population was caused by humans which there’s no way to tell, they might try to improve human habits try not to begin wars, work on helping each other, and most importantly don’t harm there plant.
