The breaking down of rock on Earth's surface into smaller pieces.
What is weathering?
Wind and water can carry sand and small pieces of rock to new locations. True or False
What is True?
Volcanoes change Earth's surface...(slowly/quickly)
What is quickly?
The difference between weathering and erosion is: a) weathering causes a quick change in landforms and erosion causes a slow change in landforms. b) weathering breaks rocks into sediments and erosion moves sediment from one place to another.
What is b?
What is not an agent of erosion? (gravity, sediment, or wind)
What is sediments?
The process by which natural forces move weathered rock and soil from one place to another.
What is erosion?
When rainwater seeps into cracks in rocks and __________, it expands and causes the rock to split apart.
What is freezes?
Weathering changes Earth's surface...(slowly/quickly)
What is slowly?
The difference between erosion and deposition is: a) erosion moves sediment from one place to another and deposition is a physical feature on the Earth. b) deposition is the process of dropping , or depositing , sediment in a new location and erosion is the process of moving sediment from one place to another.
What is b)?
Gigantic formations of ice that moves slowly over the land.
What is a glacier?
The mixture of sediment deposited directly by a glacier.
What is till?
A river flowing across a wide flood plain begins to form loop-like bends.
What is meanders?
Creep is a very ________ downhill movement of rock and soil.
What is slow?
What is the difference in a mudflow and a creep? a) mudflows are rapid downhill movements of water, soil, and rock. Creeps are slow downhill movements. b) Creeps move only water and mudflows move mud.
What is a)?
A wide sloping deposit of sediment formed where a stream leaves a mountain range.
What is an alluvial fan?
The process in which rock fragments freeze to the bottom of a glacier and the are carried away when the glacier moves is called...
What is plucking?
The process that lays down sediment in a new location.
What is deposition?
What increases runoff? (cutting down trees or flattening the land)
What is cutting down trees?
The difference between a moraine and a dune is: a) Moraines are leftover from glaciers when they melt and dunes are left over from rivers when they dry up. b) Moraines are leftover from glaciers when they melt and dunes are formed when sand is blown away and deposited elsewhere.
What is b)?
Large piles of sediment that are leftover from glaciers when they melt.
What are moraines?
The sudden movement of rocks and soil down the side of a hill because of gravity and rain.
What is a landslide?
What is evidence that an area was once covered by a glacier? (u-shaped valley or v-shaped valley)
What is a u-shaped valley?
Landslides are quick changes to the land. They can be caused by: (magma and rain or gravity and rain)
What is gravity and rain?
The difference between physical and chemical weathering is: a) Physical weathering just breaks things apart and chemical weathering changes the rocks forever. b) Physical weathering breaks things apart and chemical weathering burns rocks with chemicals.
What is a)?
Landslides, mudflows, slump, and creep are all examples of...
What are mass movement?
