Question | Answer |
---|---|
The breakdown of rock into smaller pieces called sediments. | Weathering |
Force that builds things up? | Constructive Force |
Force that breaks things down or destroys? | Deconstructive Force |
Flat area of the mouth of a river where sediments have been deposited? | Delta |
A landform or structure that prevents flooding. | Levee |
How does ice change the shapes of rock?? | Ice breaks rock by expanding in small openings through freeze and thaw. |
How was the Grand Canyon formed? | The Colorado River eroded the land over time. |
What are the two types of weathering? | Chemical and mechanical (physical) |
Explain weathering, erosion, and deposition | Weathering breaks down rock into sediments. Erosion carries sediment away. Deposition drops sediment off into a new place |
Tree roots or plant roots causing cracks in rocks is an example of what? | Physical (mechanical) weathering |
What is erosion? | The process of moving rock and soil from one location to another. |
What things causes erosion? | Wind, water, and glaciers |
What is the greatest force of erosion? | Water |
What carries sand away from beaches? | Waves. |
What projects out into the water to protect the shoreline | Jetty |
What is caused when wind carries sand? | Sand dunes |
The process of rocks and soil being dropped in a new location? | Deposition |
What can be produced by volcanic eruptions? | Mountains |
What is caused by magma rising to the surface of the earth, which causes bubbles of gas to appear in it? | Volcanoes |
A sudden release of energy from the earth's crust that causes sudden movements? | Earthquake |
What causes earthquakes? | Tectonic plates sliding past each other. |
What instrument is used to measure earthquakes? | Seismograph |
What causes Tsunamis? | Earthquakes or underwater volcanic eruptions |
Scientist who studies earthquakes and seismic waves are called? | Seismologist |
What can be changed, or new ones formed by weathering, erosion, and deposition? | Landforms |
Acid rain is an example of a physical or chemical weathering process? | Chemical |
What is it called when magma burst out of the earth? | Lava |
What is a cinder cone volcano? | An explosive volcano that shoots ash and lava into the air |
What is a composite volcano? | A volcano made with alternating layers of lava and ash |
What is a shield volcano? | A volcano with a bowl like opening with slow moving lava |
A fracture or break in the earths crust? | Fault |
What is the slow-moving flow of ice and snow called? | Glacier |
Name Georgia's geographical regions | Appalachians, Ridge & Valley's, Blue Ridge, Piedmont, Upper & Lower Coastal plains. |
What are landforms? | Structures on the earth's surface. |
Mountains, hills, plateaus, and plains? | The four major types of landforms. |
What is a mountain? | A very tall rocky land that may have a pointed top. |
What is a plateau? | A higher area with a flat top. |
What is are hills? | Taller than plains, but shorter than mountains. They are less than a 1000 feet high and may be covered in grass. |
What are plains? | Large area of flat, smooth land at a low elevation. |
What is a valley? | An area between mountains and hills |
Land that is surrounded completely by water? | Island |
A narrow valley with steep sides? | Canyon |
A natural flowing waterway? | River |
A freshwater body completely surrounded by land? | Lake |
When flying particles strike and break off more particles? | Abrasian |
What are landslides? | The movement of rock, earth, or debris down a sloped section of land. |
What is a sinkhole? | A hole in the ground that forms when water dissolves surface rock such as limestone. |
A flat-topped mountain or hill is called a? | Mesa |
