100

The layer of the Earth that includes living organisms

biosphere

100

All of the cycles we learned about involve ELEMENTS except for the _______ cycle, which involves a MOLECULE.

water cycle (H2O is a molecule)

100

How do we get nitrogen?

We have to get it through our food; we cannot just breathe it in. 

100

Rico is at the beach watching the waves. Which of these parts of the Earth system interacts with the hydrosphere to produce the waves at the beach? 

Atmosphere

100

What is the largest reservoir of water on the planet? 

oceans

200

Which sphere contains all the frozen water on Earth? All liquid water? 

Cryosphere; hydrosphere

200

Of the four elements/molecules we learned about, what two nutrients might be added to fertilizer to help crops grow? (These elements are "limiting factors" in the soil)

nitrogen and phosphorus

200

How do plants get nitrogen? 

They absorb it from the soil with the help of nitrogen-fixing bacteria. 

200

Which spheres cause weather and clouds to form?

hydrosphere and atmosphere

200

What powers the hydrological cycle?

the Sun/ how hot the atmosphere is

300

Which sphere contains all sediment, minerals and rock? Which one contains all of the gases around Earth?

geosphere, atmosphere

300

All of the materials we have on Earth have been here for a very long time, and are constantly being recycled. Based on this information, would scientists consider the Earth a mostly open or mostly closed system? 

Mostly closed system

300

What are two ways carbon is taken out of the atmosphere?

plants/ photosynthesis and ocean absorbs it

300

Soil is a combination of which spheres?

Bio, geo, (hydro)

300

Water goes from a liquid to a gas in what process? It goes from a gas to a liquid in what process?

Evaporation; condensation

400

78% of this sphere is Nitrogen

atmosphere

400

Too much fertilizer on crops may be washed off whenever it rains and "run-off" into nearby bodies of water. What effect does this cause?

eutrophication/ algae blooms

400
Provide at least two ways that the biosphere impacts the carbon cycle.

Plants take in carbon from the atmosphere, animals release carbon to the atmosphere, living things die and become fossil fuels... 

400

A volcano erupts, putting carbon dioxide and smoke into the air. Which of the spheres are interacting AND what cycle is involved?

geosphere and atmosphere; carbon cycle

400

Which sphere contains the most phosphorus? Which sphere would you rarely ever find phosphorus?

geosphere, atmosphere

500

List all 5 spheres and what their prefixes mean?

Bio- life; geo- rock; atmo- air; hydro- water; cryo- ice

500

Give three ways that the sun affects Earth's spheres. 

biosphere-- plants need sunlight to live/ photosynthesis

atmosphere-- heats our air

hydrosphere-- evaporates/ heats water

cryosphere-- could melt ice

500

What is the difference between the "short cycle" and "long cycle" in the carbon cycle?

"Short cycle"= plants take in carbon from atmosphere; animals release carbon to the atmosphere

"Long Cycle"= when living things die, they are buried in soil and rocks, and eventually become fossil fuels

500

Carbon in the air gets taken in by a plant. The plant eventually dies, decomposes, and becomes part of fossil fuels over millions of years. Humans extract and burn them for electricity production. What order of spheres did the carbon cycle through?

atmosphere --> biosphere --> geosphere --> atmosphere

500

What is it called when trees or plants "sweat"? What causes this?

transpiration; heat from the atmosphere/ sun
