Weathering Erosion and Deposition
What is the process by which rocks break down into smaller pieces over time?
What is Weathering
What process causes tectonic plates to move?
Plate tectonics
Describe the three main types of rocks.
What are Sedimentary, Metamorphic and Igneous
What is it called when the plates move apart in the middle of the ocean and new rock is formed
What is a Mid-Ocean Ridge?
What are some causes of landforms changing over time?
Weathering and Erosion
What are the three main agents of weathering? (Need Two)
What are Water, Wind and Gravity?
What drives the movement of tectonic plates?
What are Convection Currents?
How do igneous rocks form?
Cooling Lava or Magma
Name one of the four pieces of evidence used to support the theory of continental drift.
Fossil evidence, rock evidence, glacial evidence, or fit of continents
How does erosion contribute to the formation of valleys?
Valley erosion is the process in which rushing streams and rivers wear away their banks
What is erosion?
What is moving sediment from one place to another? Take It!
How do tectonic plates contribute to the formation of mountain ranges?
Tectonic plates crashing into each other and rising up.
Explain the process by which sedimentary rocks are formed.
Sediment Compacting and Cementing
What is the name of the supercontinent proposed by Wegener?
Pangaea
Explain how wind can cause erosion.
Strong winds that physically move lighter, less dense soil particles such as organic matter, clay, and silt particles that can act like sand paper
Give an example of a landform created by deposition.
What are Beaches, Deltas, and Sand Dunes?
Which type of plate is denser, continental or oceanic?
Oceanic plates
How do rocks change from one type to another in the rock cycle?
Melting, Metamorphism, and Erosion and Sedimentation
What is the theory that suggests that the Earth's continents were once a single landmass called?
Continental drift
What factors can lead to the formation of a canyon?
The movement of rivers, the processes of weathering and erosion, and tectonic activity create canyons
How does climate affect the rate of weathering and erosion?
High temperatures and greater rainfall increase the rate of chemical weathering.
What are the three types of plate boundaries?
What are divergent, convergent, and transform.
How would I go from a Metamorphic Rock to an Igneous Rock back to a Metamorphic Rock?
Metamorphic Rock melts into lava/magma. Magma cools to form Igneous rock. Heat and Pressure on the Igneous rock to form Metamorphic.
What is the location called where most of the Earth's Volcanos are located?
What is the Ring of Fire?
Describe how glaciers shape and reshape the landscape.
The ice erodes the land surface and carries the broken rocks and soil debris far from their original places, resulting in some interesting glacial landforms.
