Energy Source for the water cycle

What is the Sun?

100

All living (organic) matter is made up of this element.

What is CARBON?

100

These micro-organisms play an important role in the nitrogen cycle.

What are Bacteria?

100

Most phosphorus is stored in these.

What are rocks?

100

Rivers, lakes, oceans and groundwater all make up this sphere

What is the hydrosphere?

200

Rain, sleet, snow and hail are all...

What is precipitation?

200

This is a major store of carbon underground made from dead plants and animals from millions of years ago. 

What are fossil fuels?

200

This is the most abundant gas in the atmosphere.

What is nitrogen?

200

This sphere plays a major role in the phosphorus cycle.

What is the geosphere?

200

This sphere extends from the Earth's crust to the mantle.

What is the Geosphere?

300

Two major processes in the hydrologic cycle.

What are evaporation and precipitation?

300

Two major processes involved in the carbon cycle

What are PHOTOSYNTHESIS and CELLULAR RESPIRATION?

300

Two major processes in the Nitrogen Cycle. 

What are nitrogen-fixation and denitrification by bacteria?

300

Two major processes in the phosphorus cycle.

What are weathering and erosion?

300

This process occurs when water evaporates from the leaves of plants.

What is transpiration?

400

This process makes clouds.

What is condensation?

400

Respiration, burning fossil fuels and decay all add this gas to the atmosphere.

What is CARBON DIOXIDE?

400

Consumers are unable to use nitrogen gas from the atmosphere. How do they get the nitrogen they need?

What is EATING?
400

This is how animals get the phosphorus they need. 

What is EATING?

400

Water soaks through underground rocks into caves involves which sphere?

What is the hydrosphere?

500

When water runs over the land, this is called...

What is runoff?

500

What process removes carbon dioxide from the atmosphere?

What is PHOTOSYNTHESIS?

500

TRUE OR FALSE: 

The nitrogen cycle differs from the carbon cycle because humans cannot influence the nitrogen cycle

What is FALSE? 


*Humans create air pollution which leads to acid rain*

500

TRUE OR FALSE: 

Humans disrupt the phosphorus cycle by overusing fertilizers.

What is TRUE?

500

This sphere is not involved in the phosphorus cycle.

What is the atmosphere?
