What is the Plate tectonics theory?
This theory states that Earth’s surface is broken into large, rigid pieces that move with respect to each other.
100
What are tectonic plates?
Scientists have identified 15 of these large objects
100
What is convection in the mantle.
This causes tectonic plates to move.
100
What are lava flow and explosive eruption
These are the two major types of volcanic eruption
100
What is weathering
This process refers to a mechanical and chemical processes that change Earth’s surface over time.
200
What is the crust
This layer of the earth is where humans live.
200
What is the South American Plate
Paraguay is located on this plate
200
What is a convergent boundary without subduction
This boundary causes mountains like the Himalayas
200
What are earthquakes
These are vibrations caused by the rupture and sudden movement of rocks along a break or a crack in Earth’s crust.
200
What is sediment
Weathering breaks down rocks into this.
300
What is the lithosphere
The rocks in this layer (sphere) the are strong and do not bend easily.
300
What is a transform boundary
This boundary is when two plates slide past one another, like two cars passing on a street.
300
What is a mid-ocean ridge
This feature is found at underwater divergent boundaries.
300
What are faults
These are often found near plate boundaries
300
What is ice, wind, water, gravity, organisms.
These 5 things can cause physical weathering
400
What is the lithosphere
The crust and uppermost part of the mantle, make up the this layer (sphere) _______.
400
What is a convergent boundary with subduction.
Volcanos are found at this type of convergent boundary
400
What is are divergent boundaries and convergent boundaries with subduction
Volcanos are found at these two types of boundaries
400
What are convergent boundaries with subduction
The most powerful earthquakes are found at these types of boundaries
400
What is chemical weathering
Unlike physical weathering, this type of weathering changes the composition of the rocks
500
What is the asthenosphere
This layer (sphere) of earth is hotter than the lithosphere and can bend more easily.
500
What is Pangaea
North America and Europe once were part of this large continent.
500
What are ALL plate boundaries
Earthquakes are found at these types of boundaries
500
What is the ring of fire.
70%+ of all volcanos and 80%+ of all earthquakes occur along this feature.
500
What is erosion and deposition.
After a rock is weathered, first this process moves the rock and then another process deposits the sediment.
