What is deposition
When rocks and sediment get deposited somewhere to make a landform
Water that changes from liquid to gas when it cools down
condensation
How is carbon is absorbed from the atmosphere?
plants through photosynthesis
What is burrowing?
when animals dig holes
What is hydrolysis
when water softens rocks over time
________ creates flood plains sand dunes and sand bars
deposition
What is the sun's and gravity's role in the water cycle?
the sun makes it go up (evaporation) and gravity makes it go down (precipitation + runoff)
What are fossil fuels?
dead animals and plants that become sources of energy after millions of years
Arches and mushroom rock formations are caused by _________ from wind
abrasion
What are the 3 types of chemical weathering?
multiple answers
Landslides, mudflows and slump/creeps are caused by _________
erosion by gravity
What is transpiration?
How is global warming affected by the carbon cycle?
When fossil fuels are burned it released carbon dioxide into the atmosphere which traps heat in the earth
