Plate Tectonic Boundaries
When plate boundaries move towards each other, what will likely occur?
mountain building
What causes a heat transfer in the Earth?
convection currents in the mantle
Volcanoes and earthquakes often occur in similar locations is evidence of continental drift. (True/ False)
True
When tectonic plates collide
What is convergent boundaries?
What plate movement causes mountains?
Convergent movement, colliding
Which layer of the Earth does convection currents (heat transfer) occur?
Mantle
Who was the creator of continental drift?
Alfred Wegener
Plate tectonics can move because of what in the mantle?
What is convection currents?
Piece of the Earth’s crust that moves and interacts with other plates, causing geologic events to occur.
What are some reasons that scientists use models to study the layers of the Earth?
1. Cannot directly observe the layers of the Earth
2. Earth's layers are too big to observe
3. Scientists cannot drill past the crust
Earthquakes are a result of which type of plate movement?
What is transform plate movement?
What movement forms mountains?
What is convergent plate movement?
How are mid-ocean ridges formed?
Divergent boundary (spreading boundary)
The Earth's core is ____(hotter, colder) and has ____(more, less) iron than the Earth's crust.
hotter, more iron
Where do earthquakes and volcanic activity occur?
a. oceanic crust
b. Mountain
c. boundaries of the plate tectonics
What are the boundaries of the plate tectonics?
Tectonic plates make up the Earth's what?
Crust
The name of the fault in California where earthquakes occur.
What is San Andreas Fault?
Where does the main heat source come from to cause the plate tectonics to move?
EARTH'S MANTLE AND CORE
What are 3 pieces of evidence that prove continental drift?
1. Fossils of the same plants and animals in different places
2. Shaped like a puzzle
3. Similar mountain range
4. Similar rock types
What forms mid-ocean ridges?
