Earth's Moving Surface
Tectonic plates are made of...
What is crust and rigid mantle.
How is weathering related to sediment?
What is weathering creates sediment.
The process of loosening and transporting rock and sediment...
Erosion
Define mid ocean ridges.
What is, occur along divergent boundaries and new ocean floor is created.
Two types of 'weather' that are more common near plate boundaries than in the middle of a tectonic plate.
What is earthquakes and volcanoes.
This portion of the mantle is hotter than the lithosphere and can bend more easily.
What is the asthenosphere?
What provides the forces that can cause rock to move downhill?
What is gravity.
The largest earthquakes occur...
At convergent boundaries.
How is erosion different from weathering?
Weathering breaks down rock. Erosion loosens and moves weather material.
Clay, sand, and rock fragments are examples of _____.
Sediment.
Where two plates move away from each other.
What is a divergent boundary?
Water causes most ____ on Earth.
Define magma.
Molten rock stored beneath Earth's surface.
What kind of eruption would you expect to see if you could travel down to a mid ocean ridge?
What is lava flows that form unique shapes.
Explain the difference between physical and chemical weathering.
What is physical weathering breaks down materials without changing the composition. Chemical weathering changes the composition of the material.
Convection is caused by
What is density and thermal energy?
Why would sediment settle out of river water as it enters an ocean?
What is as the water enters and ocean, the water spreads out and slows down, allowing material to be deposited.
Relationship between faults and plate boundaries.
What is faults occur at plate boundaries and elsewhere.
Two plates colliding with each other.
What is convergent boundaries.
Give an example of chemical weathering.
What is...
What is a type of boundary where one plate subducts beneath another plate.
What are the three geologic features that form when an oceanic plate converges with a continental plate?
What is subduction zone, deep ocean trench, and mountains that have volcanic peaks.
Convergent boundary with no subduction.
Two plates sliding parallel to each other.
What is transform boundaries.
Sand dunes in deserts are made by ___.
Blowing wind.
