Erosion
The process of moving and carrying of sediment and rocks from one place to another.
Erosion
This is a giant wave of water caused by an earthquake.
Tsunami
This is the breaking down of rocks into smaller pieces.
Weathering
A natural land feature on Earth's surface
Landforms
An example of deposition
sand dunes, deltas, etc
a slowly moving mass or river of ice formed by the accumulation and compaction of snow
Glaciers
This is a sudden shaking of the earth's crust along a fault
Earthquake
When water in cracks of rocks freeze, it _______________ causing the rock to break apart.
Expands
Very hot, partly melted rock that is below the Earth's surface
Magma
An example of erosion
wind carrying small pieces of rock away, water carrying rock into a stream, etc
These form when sediment or sand is eroded by wind and create hills and mounds.
Sand Dunes
A landform that forms at an opening in Earth's crust where magma reaches the surface
Volcano
These can grow through rock causing it to break apart.
Plant Roots
Magma that reaches the Earth's surface
Lava
An example of weathering
ice freezing in cracks of rocks and breaking, rocks scraping each other, etc
The laying down or dropping off of sediment.
Deposition
The rapid downhill movement of a large amount of rock and soil
Mudslide
Rocks can feel very _____________ if they have been rolling in water (Think of a rock in a stream or lake)
What is smooth?
Fast moving water that can uproot trees, carry away big rocks, and change where rivers flow
Flood
Periods of unusually low rain or snowfall
Drought
This land feature forms at the base of rivers where sediment is deposited.
Deltas
Name 3 ways land can be eroded quickly or suddenly. (example: earthquake)
Tsunami, earthquake, volcano, landslide, mudslide, lahar, tornado etc.
Name 2 causes of weathering.
water, wind, plants
A break or crack in rocks where Earth's crust can move suddenly
Fault
Type of weathering that can be caused by acid rain (Hint: NOT physical weathering)
Chemical Weathering
