True or False: The Tectonic Plates move at the same speeds and the same directions.
False
Each one has its own unique speed and direction
Name the 4 layers of the Earth.
Crust, Mantle, Outer Core, Inner Core
What is the landmass called when all the Continents were connected?
Pangea
Plate Converging creates what?
Mountains
What is uplift?
The Earth's crust rising.
Name the 3 plate movements and show with your hands what the directions are.
Convergent, Divergent, and Transform
What causes the plates to move?
Convection Currents from the mantle
What are the plates doing between South America and Africa?
Diverging
Plates Diverging creates what?
Ridges/Valleys
If the erosion rate is bigger than the uplift rate, will the mountain get taller or smaller?
Smaller
What is subduction?
When one plate goes underneath another
What layer cannot let S-Waves through and why?
Outer core. It is liquid.
What creates new ocean floor as the plates diverge?
Magma
Volcanoes are formed with what type of crust meets what type of crust?
Continental meets Oceanic
What type of plate movement creates earthquakes?
Transform
Name the 2 types of crust
Continental and Oceanic
What happens to the temperature and pressure as you rise to the surface of the Earth?
The temperature gets cooler
The pressure becomes less
What are the boundaries of the tectonic plates called?
Fault Lines
How is sedimentary rock formed?
Sand, rocks, and dirt layer on top of each other over time.
What are seismographs?
Instruments that measure earthquakes and seismic waves.
Which type of crust is the most dense? Explain why.
Oceanic. It is made of a more dense material Basalt.
What is the outer core made of?
Liquid Magnetic Metals
What is an argument, that has to do with fossils, that prove that Pangea was a real thing?
Fossils of the same kind are found at the places where continents were connected.
What are hotspots?
Magma fills the cracks in the crust, creating islands.
What is erosion?
Wind, water, and waterflow carry away rocks, creating newly formed rocks and canyons.
