ET Water & Carbon Cycles 4/4/24

CO2 is a greenhouse gas, therefore it can impact climate by:

• Allow plants to grow really well
• Creating acidic oceans
• Trap heat in the atmosphere
• Stabilize earth's seasonal variations

The ocean is a reservoir of carbon, which means:

• Carbon easily dissolves into, and out of, the ocean.
• Carbon is essential to life in the ocean.
• The ocean is a storage of carbon
• Carbon does not last long in the oceans.

Excess CO2 in the ocean's photic zone can lead to:

• Fish kills
• Less oxygen
• Slight acidic waters, called acidification
• Upwelling and El Nino

C indicates which process?

• Transpiration

• Sublimation

• Condensation

• Precipitation

Which of the following are types of freshwater that can be used by people?

Select all that are true.

• groundwater

• ice caps and glaciers

• oceans

• rivers

• lakes

Why does groundwater usually require less treatment than surface water?

• The layers of Earth protect groundwater from pollutants.

• As groundwater sinks into the ground, the layers of rock act like a natural filter and remove pollutants from the water.

• Surface water has more exposure to pollutants in runoff and the atmosphere.

• all of the above
