lesson 17- inter relationship between water and carbon cycles

Question 1

erosion

Answer 1

water in rivers erodes river banks and ‘flushes out’ organic matter from the soil. This is carried down the river into the oceans store (38,000 PTC)

Question 2

evaporation

Answer 2

CO2-> greenhouse effect, so more water absorbs heat, evaporates and causes tropical storms -> more rainfall -> more erosion (Loop)

Question 3

photosynthesis

Answer 3

H20 + CO2 are needed for plants to store carbon and release oxygen, and absorb and use water

Question 4

decomposition

Answer 4

microorganisms need water to thrive and break down organic matter, releasing carbon dioxide

Question 5

carbon dioxide effect on stomatas

Answer 5

higher carbon dioxide level- stomata contracts and water is held inside the plant
-reduces transpiration and plants take in less water from the environment as they have more inside them
