Weathering / Erosion
What is the process that breaks down rocks into smaller pieces?
Weathering
What force scrapes and erodes the land?
(water, wind, glaciers, gravity, chemicals)
glaciers
What force causes water to flow down the hill as run-off?
Gravity
condensation
Name for the process when sediments are dropped or settle in a new location?
Deposition
What type of weathering happens when rocks are broken down by freezing and thawing? (chemical, physical, biological)
physical
The further a rock moves, the _____________ (more or less) the rock is weathered.
more
broken lava rock
This is the step of the water cycle where the Sun heats water and water changes from a liquid to a gas
evaporation
What is one landform that is formed as the river slows down and enters a larger body of water.
delta
Most common natural force to cause erosion?
water
What are the 3-4 steps that cause potholes to form?
water gets in cracks
water freezes & expands, weathering the blacktop
water erodes the pieces away.
Name one effect of erosion.
Mudslides; flooding
What is it called when snow, hail, rain fall from the sky?
Precipitation
Waves create this landform by depositing small sediments.
beach, sand, sand dunes
The process by which soil and rock MOVE from one place of the earth to another by forces of rain and/or wind
Erosion
Bigger slope, faster water, more weathering & erosion
How do plants and trees prevent erosion?
The plants/trees soak up water
This is the step of the water cycle where water is evaporated from plant leaves
transpiration
A landform that can be formed as wind leaves sand in one area.
sand dunes
Forces that can cause weathering?
wind, water, ice, humans, animals, chemicals
What is sand really made from?
smaller pieces of rock and shells
What is the difference between weathering and erosion?
Weathering breaks apart and erosion carries it away
infiltration
What is one landform that is formed as the river slows down and enters a larger body of water.
Delta
