The Carbon Cycle and Climate Change Test

How do you calculate the rate of change?

It is very similar to slope. You put the ppm or temperature on top and the years on the bottom and then divide. This process is rise over run. Then you divide the top number by the bottom number and round to the nearest tenth.

Name the process in which plants take in sunlight and the CO2 from the atmosphere.

photosynthesis

The grasslands biome is considered to be?

the Bread Basket of our country because it is a hub of agriculture activites, particulary grain farming.

What is the definition of caring capasity?

the number of people, other living organisms, or crops that a region can support without environmental degradation

Explain how the destruction of the rainforest leads in a loss in biodiversity AND how it amplifies the effects of climate change.

-The rainforest biome has the highest amount of species diversity on planet Earth. -We are losing a tremendous amount of biodiversity as ever increasing amount of rainforest are cut down. -As more and more rainforest is cut down it amplifies the effects of climate change. -The rainforest absorbs billions of tons of carbon dioxide every year and is a major carbon sink. -Without the rainforest acting as a buffer, less carbon dioxide from human activities will be offset.

how do scientist recunstruct past climate?

-fossil corals -Ice core -pollin -dust -volcanic debris -treen ring data -sediment data

How much of the earth's carbon can be found in the deep ocean? How long has that carbon been in the deep ocean?

60% 100 years

What is the relationship between climate change and ocean acidification? How does ocean acidification affect marine organisms? How is ocean acidification affecting businesses that rely on marine resources?

As atmospheric carbon dioxide levels rise oceans absorb more CO2. 2 3

What is the deffiniton of biotic potential?

Biotic potential is the ability of a population of living species to increase under ideal environmental conditions - sufficient food supply, no predators, and a lack of disease.

List at least three factors (sources) that would most likely cause an increase in atmospheric carbon dioxide.

Burning fossil fuels, Deforestation, Slash and burn agriculture, volcanic eruptions

Use the following terms to describe how climate change might affect the grasslands biome: Biome, limiting factor, precipitation, temperature, crops

Climate change can lead to a change in precipitation and temperatures. Which are limiting factors that can affect a population's distribution and abundance. For example, if there is an increase in extreme weather events it may negatively affect the grassland ecosystem. The grasslands biome is home to many of North America"s crop such as wheat and corn.

What is the deffinition of the greenhouse effect?

Greenhouse gases trap heat in Earth's atmosphere which warms Earth's climate Methane, carbon dioxide, water vapor

What characteristics of the grasslands biome make it a critical source of food for the U.S. and other countries?

Perfect temperature to grow things and raise animals (not too hot not too cold) and it has grass.

In the penguin exersize, when the air temp, sea ice extent, krill densities and adelie penguin population go down, what happnes to that species of penguin

The Adeline penguin population goes down and the chinstrap pengiun population rises

What biome in North America has the lowest biodiversity?

The Arctic

What biome in North America has the highest biodiversity?

The Equator

Explain how deforestation is resulting in devastating consequences for our enviourment.

Through deforestation less and less Co2 is being admitted into the atmosphere.

If rainfall in the grasslands biome decrease as the climate change model suggests, to what type of the biome would the grasslands biome convert?

The grasslands would convert to dessert

What is the general trend of biodiversity in biomes as the latitude moves from the Arctic region towards the equator?

The temperature rises the closer you get to the equator.

What human activity has added the most carbon to the atmosphere? Select one: a. burning fossil fuels b. mining fossil fuels c. cutting down the rainforest d. increasing soil erosion e. none of the above

a. burning fossil fuels

Where is underground water stored?

aquafiers

Which of the following would most likely cause in increase in atmospheric carbon dioxide? Select one: a. Biological processes such as photosynthesis b. Geochemical processes such as the release of gas from volcanoes c. Mixed biogeochemical processes, such as the formation of fossil fuels d. All of the above

b. Geochemical processes such as the release of gas from volcanoes

What relatively recent development is greatly impacting the carbon cycle? Select one: a. Formation of limestone and other carbon-based rocks b. Photosynthesis c. Combustion of fossil fuels d. Cellular respiration e. Formation of fossil fuels

c. Combustion of fossil fuels Correct

what are the two biggest components of the greenhouse effect?

clouds and vapor

Carbon dioxide is produced by Select one: a. volcanic eruptions b. burning of fossil fuels c. cellular respiration d. all of the above

d. all of the above

What are the four types of H2O vapors Co2 methaine

human burning fossil fuels, burning of forests, cellular respiration, and decomposition.

What happens when the sun comes out (two processes)?

vapor or steam

What happens when the amount of carbon dioxide increases in the atmosphere?

warms the planet

How does condensation form?

when vapor is so cold so it forms clouds

When does precipitation occur?

when you cant hold anymore H2O in water cycle
