What is the process in which water turns from a liquid to a gas?
Evaporation
100
A naturally abundant, nonmetallic element that occurs in all organic compounds and can be foudn in all known forms of life.
Carbon
100
The process by which carbon cycles from the lithosphere to the atmosphere.
Eruption of gasses
100
What is the energy source that drives the water and carbon cycles?
The sun
200
What is the sphere containing all life on earth?
Biosphere
200
What is the process called when small water droplets form on small particles on dirt in the sky?
Condensation
200
A chemical reaction that occurs when plants use carbon dioxide and energy from the sun to build sugar.
Photosynthesis
200
The process by which carbon cycles from the biosphere to the lithosphere.
Burial and Sedimentation
200
The continuous movement of water from the ocean to the atmosphere to the land and back to the ocean is called a _______________________.
Water Cycle
300
What is the sphere containing all of the water on earth including oceans, streams, lakes, and ponds?
Hydrosphere
300
What is it called when water evaporates through the leaves of plants?
Transpiration
300
A chemical reaction that occurs when cells break down sugar, which results in carbon dioxide production
Respiration
300
This is one way that humans alter the carbon cycle. This allows us to generate electricity, power cars, and run factories.
Burning Fossil Fuels
300
On a hot day, the water droplets that form on a cold glass are called ________________.
condensation
400
What is the sphere containing the air, clouds, and weather?
Atmosphere
400
What is it called when water drifts off the surface of the land toward rivers, lakes, or ocean
Surface runoff
400
A process that moves particles, such as atoms or molecules, from one pl,ace to another (from higher concentration to lower concentration)
Diffusion
400
The process in which dead organisms release CO2 back into the atmosphere.
Decomposition
400
What is meant by "alternative" or "green" energy
Renewable Energy
500
What is the sphere containing all of the rocks, dirt, and soil on Earth?
Lithosphere
500
The process in which water pools in large bodies like oceans, seas, and lakes.
Accumulation
500
Wearing away and movement of rock and sediment, often by water, wind, glaciers, and waves.
Erosion
500
The largest carbon "sink" in the world is
Ocean
500
Over millions of years, the carbon in dead plants and animals that are put under heat and pressure are converted into __________________.
