Transpiration will decrease.

Consider the diagram of the water cycle. Assume that deforestation has taken place. Explain how this affects the movement of water rough this model?

sun energy

The driving force behind the water cycle and How and why water changes phase is the

increase in plant growth, because plants need carbon

2) Solar radiation travels through the earth's atmosphere and warms the planet's surface. Greenhouse gases like carbon dioxide in the earth's atmosphere reabsort the heat and warm the planet. The amounts of greenhouse gases have been increasing over the past century, causing the earth's surface temperature to increase. This gradual temperature change is thought to have many negative environmental consequences

Ground water will increase.

Consider the diagram of the water cycle. Assume we have a very cold winter with lots of snow. The mountain top is piled high with snow. Then it is spring. How will this impact the water cycle model?

evaporation : temperature increases; condensation : temperature decreases; precipitation (rain) : temperature decreases

Describe the change in phase and temperature as water moves from the oceans to the atmosphere and then retums to Earth again As rain

Water on Earth heats up and evaporates into the atmosphere, then cools and condenses to form clouds.

Describe the role of temperature change in cloud formation

It's no longer deadend of the cycle

Scientists previously referred to the long-ago deposited plant and animal remains, now buried, compacted, and transfonned into coal and oil, as the dead end of the carbon cycle. Since the Industrial Revolution, that would be an inaccurate statement. Examine the model and explain.

the water in the air evaporates because the temperature of air is rising

The climate of a place also depends upon the amount of water in the air. How do the rising temperatures around Earth affect the amount of water in the air?

it provides the energy to evaporate water on Earth into the atmosphere.

How is the sun the major source of energy in the water cycle?

armer air temperatures mean warmer ocean temperatures. This results in more precipitation and less atmospheric carbon dioxide.

There is much interdependence among the biogeochemical cycles on Earth. Explain how warner ocean water involved in these cycles.

Plants use carbon dioxide as a reactant in photosynthesis, to make usable chemical energy in the form of a sugar.

This is a typical grassland food web. It is also a small picture of an important cycle on Earth: the carbon cycle. Explain how the carbon gets into this food web.

Planting a field of wheat

This is a typical grassland food web. It is also a small picture of an important cycle on Earth: the carbon cycle. Man can impact the carbon cycle in a negative way. What conclusion would NOT negatively impact the carbon cycle.

precipitation

Water that has evaporated returns to the Earth

Sun's energy

What is the main source of energy that drives the water cycle

transpiration

Like animals, plans undergo cellular respiration to produce energy. Plants use oxygen and Q. release carbon dioxide and water. Water returns to the atmosphere and becomes part of the water cycle through the process of
