Fossil fuels require a lot of carbon to burn, which releases carbon into the atmosphere. Fossil fuels are rich in carbon, and burning them returns carbon to the soil. Fossil fuels are rich in carbon, and burning them returns carbon to the soil. Fossil fuels require a lot of carbon to burn, which takes carbon out of the atmosphere. Fossil fuels require a lot of carbon to burn, which takes carbon out of the atmosphere. Fossil fuels are rich in carbon, and burning them releases carbon into the atmosphere. Fossil fuels are rich in carbon, and burning them releases carbon into the atmosphere.
Answer:
Fossil fuels are rich in carbon, and burning them releases carbon into the atmosphere.
Explanation:
The amount of carbon in the form of carbon dioxide in the atmosphere is about 0.03% by volume. This value is kept fairly constant by a natural process known as the CARBON CYCLE. This involves carbon dioxide being continually removed from the atmosphere by plants in photosynthesis, rain water as weak acids while in order to maintain this balance, carbon dioxide is at the same time returned to the atmosphere by:
→ burning of carbon containing substances (fossil fuel)
→ respiration of plants and animals and
→Decomposition of organic substances.
Hence, Fossil fuels which are rich in carbon content releases carbon into the atmosphere when burnt.
Answer:
Fossil fuels are rich in carbon, and burning them releases carbon into the atmosphere.
Explanation:
Carbon moves from fossil fuels to the atmosphere when fuels are burned. When humans burn fossil fuels to power factories, power plants, cars and trucks, most of the carbon quickly enters the atmosphere as carbon dioxide gas. Each year, five and a half billion tons of carbon is released by burning fossil fuels.
How does deforestation have an affect on the water cycle?
Answer:
Forests help control the water cycle by regulating precipitation, evaporation and flows. Layers of forest canopy, branches and roots can store and release water vapor, which controls rainfall. ... Deforestation weakens this process, leading to irregular rainfall patterns including drought and flooding.
What is the main entry point for nutrients in the littoral zone in lakes? How does this affect the biomass of this zone? How does it affect species diversity?
Answer:
D
the littoral zone is close to the shore and is partially submerged with shallow water. It is the uppermost zone of the aquatic water body. It is the part of lakes, rivers, ponds and sea.
Explanation:
took the test
The main entry point for nutrients in the littoral zone in lakes is runoff from the surrounding land.
This runoff can carry a variety of nutrients, including nitrogen, phosphorus, and potassium. These nutrients are essential for plant growth, and they can lead to a significant increase in the biomass of the littoral zone. The increased biomass in the littoral zone can support a greater diversity of species.
This is because there are more food sources available, and there is more space for different species to live. However, the increased biomass can also lead to eutrophication, which is the excessive growth of algae. This can make the water cloudy and foul-smelling, and it can also deplete the oxygen levels in the water.

Whats the difference between meteoroid and asteroid ?
Answer:
"A meteoroid is “a small, rocky or metallic body revolving in interplanetary space around the sun. A meteoroid is significantly smaller than an asteroid, ranging from small grains or particles to the size of large boulders.” In other words, a meteoroid is a “space rock” smaller than an asteroid."
Answer:An asteroid is a small rocky object that orbits the Sun. ... A meteor is what happens when a meteoroid – a small piece of an asteroid or comet – burns up upon entering Earth's atmosphere, creating a streak of light in the sky. An asteroid is a small rocky object that orbits the Sun.

Use your model to explain how one of these metamorphic rocks: gneiss, marble, or quartzite could become igneous or sedimentary rock and how that rock could become a third type of rock.
my model: I could add to my model if it is needed in the answer.
Answer:
If the newly formed metamorphic rock continues to heat, it can eventually melt and become molten (magma). When the molten rock cools it forms an igneous rock. Metamorphic rocks can form from either sedimentary or igneous rocks.
Explanation:
The freshly created metamorphic rock may ultimately melt and become molten if it is heated further (magma). A rock called an igneous rock is created when molten rock cools. Sedimentary or igneous rocks can develop into metamorphic rocks.
What are Igneous and Metamorphic rocks?To alter shape is to undergo metamorphism. It refers to alterations in rocks (protoliths) in the solid state, as understood by geologists (i.e. not by melting the rock wholesale). Metamorphosis may be compared to cooking. Changes take occurred when ingredients are combined and put at a different temperature (or pressure).
The thermal energy that propels metamorphism comes from a variety of sources. It goes without saying that the contact zone will become quite hot when an igneous mass with a temperature of 1200 degrees C intrudes into an unprepared host rock. Contact metamorphism, a rock-baking process, results from this.
Due to the heat generated by volcanic activity along the mid-ocean ridges, hydrothermal metamorphism takes place there. Anywhere contact metamorphism takes place, intrusion of igneous rocks is the driving force. Both of these types undergo metamorphism at low pressures and high temperatures.
Therefore, igneous rock is created when molten rock cools. Sedimentary or igneous rocks can develop into metamorphic rocks.

1. Tom and Tina decided they wanted to start a family. Tom knew his grandfather had sickle-cell disease. Sickle-cell disease is a recessive disorder that causes blood cells to stiffen and take on a crescent shape. These blood cells have a difficult time moving through the blood vessels and can cause health problems. Tina didn’t know of any family members that had it. Still, before they got pregnant they both went to the doctor for genetic tests. The doctor found that even though Tom and Tina were healthy, they both carried the gene for sickle-cell disease. Make a Punnett Square to determine the probability of Tom and Tina’s child having sickle-cell disease.

Which statement best compares competition, cooperation, and predation between two organisms?
Cooperation is a positive interaction between the two organisms, and predation and competition result in a negative interaction for at least one organism.
Cooperation and competition are positive interactions between the two organisms, and predation results in a negative interaction for at least one organism.
Cooperation and predation are negative interactions between the two organisms, and competition results in a positive interaction for at least one organism.\
Cooperation results in a negative interaction for at least one organism, and competition and predation are positive interactions between the two
Answer:
First option: "Cooperation is a positive interaction between the two organisms, and predation and competition result in a negative interaction for at least one organism."
Explanation:
Cooperation in this case, is the act of two or more organisms, working together and helping each other, in order to increase their chances of survival (this is a good thing, and benefits both species).
Competition in this case, is when different organisms fight over limited resources (this is terrible for both species involved, because it wastes both time and energy).
Predation is when one organism preys on another, meaning they eat the organism (while this may benefit one of the organisms involved, the other will surely be dead.)
Hope this helps you :)
Answer:
Cooperation is a positive interaction between the two organisms, and predation and competition result in a negative interaction for at least one organism.
