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