Water and Carbon final

There are two processes that either add or take away small amounts of water from the hydrosphere, what is one of them?

• water being captured by sedimentary rock and subducting

• water being ejected by volcanoes

• water being evaporated into the thermosphere

• water being captured by clouds

There are multiple paths for water to go when it collects on land, which one is correct for it ending up on rivers and lakes?

• evaporation

• condensation

• runoff

• infiltration/percolation

The carbon cycle is considered a closed system, but carbon can be removed from the system for a long time by...

• photosynthesis of plants and cyanobacteria to make sugars

• combusting fossil fuels to make energy

• chemically bonding with minerals to make limestone

• chemically bonding with water to make carbonic acid

Biomass is considered a renewable energy source, because...

• it captures CO2, and forms quickly by human standards

• it captures CO2, and lithifies into rock over a long period by human standards

• it cycles CO2 via a chemical process that creates energy in organic beings

• it cycles CO2 within the fluidsphere

Fossil fuels are not considered a renewable energy source, because...

• it captures CO2, and forms quickly by human standards

• it captures CO2, and lithifies into rock over a long period by human standards

• it cycles CO2 via a chemical process that creates energy in organic beings

• it cycles CO2 within the fluidsphere

What is an important aspect of the greenhouse effect for life on Earth

• without it the Earth would be frozen

• without it the Earth would be way too hot

• it reflects energy back into space

• it protects from harmful UV radiation

Which gas contributes most to the greenhouse effect?

• methane

• water vapor

• carbon monoxide

• carbon dioxide

What are two ways carbon is put into the atmosphere?

• combustion of fossil fuels

• volcanism

• photosynthesis

• limestone formation
