What causes continental drift?

What are the movement of plate tectonics (Convection currents)

100
How is it possible that the water you drank today at one time could have been dinosaur pee?
the water that we see is the same water that has been here for billions of years, it is just moving through the water cycle
100
In what process do plants remove carbon dioxide from the air?
photosynthesis
100
Why must nitrogen be "fixed"?
the N2 gas in the air is not in a form that is usable by plants
100

This process, caused by water and wind, releases phosphates from rocks into the soil and water.

weathering

200

What are the 3 types of plate tectonics?

Convergent, Divergent, Transform


200
What is precipitation? Name 3 types.
water that has condensed in clouds and falls to the earth-rain, snow, hail, sleet
200

In what process do animals return carbon to the atmosphere?

respiration

200

What is one way that nitrogen is fixed?

nitrogen-fixing bacteria

200
How is phosphorous returned to the soil from living things?
waste, decomposition
300

Do transform boundaries form volcanoes? True or False

False.

300
How does water from lakes and oceans reenter the atmosphere?
evaporation
300
How do carbon molecules enter the soil?
decomposition
300
Why is nitrogen so important?
it is used to make amino acids, and ultimately proteins
300
How do plants obtain phosphorous?
absorb through roots (in water or soil)
400

Where are plate tectonics located?

Lithosphere and Aesthenosphere

400
How do animals return water to the ground?
urine
400

How have humans drastically altered the carbon cycle?

burning fossil fuels which releases carbon dioxide

400

What nitrogen containing chemical can be a problem when runoff enters streams?

nitrates from fertilizer

400

Organisms that obtain phosphorus by breaking down dead plants and animals.

decomposers

500

Who is the father of plate tectonics?

Alfred Wegener

500
What is transpiration?
the evaporation of water from plants
500

In the slow carbon cycle, carbon moves between the atmosphere, ocean, and rocks over millions of years. Name one natural process that stores carbon long-term and one that releases it back into the atmosphere.

volcanic activity

500

This process, carried out by bacteria, converts ammonia to nitrite and then to nitrate, a form of nitrogen usable by plants.

nitrification

500

Unlike the other biogeochemical cycles, the phosphorus cycle has no major atmospheric component. Explain how phosphorus naturally moves from rocks into living organisms and then back into the soil or water.

Phosphorus is released from rocks through weathering and erosion, absorbed by plants through the soil, passed to animals when they eat plants, and then returned to the soil or water through decomposition and waste.
