Earth's Layers | Tectonic Plates | Geohazards (Easy, Not Really That Hard) |
---|---|---|
How many layers does the Earth have?
4 layers
|
What causes earthquakes? Explain
Transform Boundaries, because the two plates get stuck and they try to force past each other causing them to slip very fast and cause major shaking in the earth.
|
What can be damaged by earthquakes?
Houses, People Dying, and Damaged Things
|
Name all the layers of the earth
Lithosphere (Crust), Mantle Layer, Outer Core, Thick Inner Core
|
What tectonic plate creates mountains? Type of Collision?
Convergent Boundary: Continent-Continent Collision
|
What is a volcano made from? Collision?
Convergent Boundaries: Continent-Oceanic Collision
|
What layer contains convection currents?
Mantle
|
What boundary creates rifts?
Divergent Boundaries
|
What can Volcanic ash lead to?
Suffocating, Death/Suffering and Poisoning Animals
|
What is each layer made out of?
Lithosphere: Silicon, aluminum, and magnesium
Mantle: Rapidly flowing magma Outer Core: Heavy Metals, nickel, and iron Inner Core: Heat and High pressure |
Ocean-Ocean Plate Collision: When two oceanic plates collide, one runs over the other which causes it to sink into the mantle; What is this called?
Subduction
|
What is a hot spot?
Volcanos categorized to have underlying magma filling it up.
|
How thick is each layer in kilometers?
Lithosphere: 6-35km, Mantle:2900km, Outer Core:2000km, Inner Core:1370km
|
What causes major earthquakes other than transform boundaries?
Faults in the deep parts of the earth.
|
Is global warming considered geohazards? Explain
Yes, because sooner or later the ozone later will go away causing the species to die out and earth to quickly change to another type of planet.
