This is the process that occurs when water changes from a liquid to a gas caused by heat from the sun.
What is evaporation?
100
The energy from this causes the water cycle.
What is the sun?
100
This is a low area of land between hills or mountains, typically with a river or stream flowing through it.
What is a valley?
100
This is the process by which wind and moving water carry away bits of rock and other material.
What is erosion?
100
This occurs when precipitation does not get absorbed into the soil or did not evaporate, and runs into reservoirs such as lakes, oceans, and streams.
What is runoff?
200
This is the cooling of water in the atmosphere changing the gas (water vapor) to a liquid (tiny water droplets).
What is condensation?
200
This is something that has a downward or upward slant.
What is a slope?
200
This is a steep rock face, especially at the edge of the sea.
What is a cliff?
200
This is the process that breaks up rocks.
What is weathering?
200
This type of erosion changes Earth's surface by weathering rock, eroding sediments, and depositing sediments in a new place. It also forms sand dunes and desert rock formations.
What is wind erosion?
300
This is the process of water moving between Earth's surface and the atmosphere.
What is the water cycle?
300
This is what forms when water vapor condenses onto tiny pieces of dust that are floating in the air, and billions of these droplets come together.
What are clouds?
300
This is a geologic feature with a flat top surface and steep sides.
What is a mesa?
300
This is a form of erosion by which sediments are added to a landform.
What is deposition?
300
This type of erosion forms canyons and deltas.
What is water erosion?
400
This happens when water droplets gather and join together, become larger and heavier droplets, and then fall from the atmosphere in the form of rain, sleet, snow or hail.
What is precipitation?
400
This is the force that causes molecules on the surface of a liquid to be pushed together and form a layer.
What is surface tension?
400
This is a ravine formed by a river in an area with little rainfall.
What is a canyon?
400
This is the process of rocks breaking apart without changing their chemical composition (ice wedging, plant roots, fast moving water)
What is physical weathering?
400
Most precipitation that falls to Earth goes directly into this.
What is the ocean?
500
This is a place where water is collected and stored for use. Examples include lakes, aquifers, and oceans.
What are reservoirs?
500
This is the process by which moisture is carried through plants from roots to the underside of leaves, where it changes to vapor and is released to the atmosphere.
What is transpiration?
500
These are triangular-shaped collections of sediments that are formed at the mouth of a river due to deposition.
What are deltas?
500
This is the decomposition of rocks due to chemical reactions occurring between the minerals in rocks and the environment (oxidation, rust, carbonic acid)
What is chemical weathering?
500
These have formed many of our lakes, they have scraped away rock to form large holes, and they have created wide valleys as they slowly scraped sediments in between mountains.
