Tectonic Plates
True of false: Tectonic plates make up the mantle
False! They make up the CRUST
Name 2 negative effects an earthquake can have on people.
injuries, deaths, loss of money, loss of belongings...
True or false: A transform boundary is when plates slide past each other
True!
Big slab of rock that moves over Earth...
Tectonic Plate(s)
Which layer of the Earth do we live on?
The Crust
Name 2 things that result from the movement of the tectonic plates.
Earthquakes, tsunamis, volcanos, mid-ocean ridges, trenches, Continental Drift...
A tsunami is the result of an...?
underwater earthquake
A divergent boundary is when.....?
2 plates separate from each other
Plate boundary where 2 plates slide past each other
Transform Plate boundary
How much does Ms. Spielman LOVEEEEE teaching 6th grade on a scale of 1-10?
10!!!! :)
What is Continental Drift and what causes it to happen?
The process where the Earth's continents are slowly drifting apart. This is caused by the movement of the tectonic plates.
What are seismic waves?
Mechanical waves of energy sent out as the result of an earthquake, which create vibrations and shake the ground
Name the 3 types of plate boundaries
Covergent, Divergent, Transform
An underwater mountain range
Mid-ocean ridge
What are the 4 layers of the Earth, in order from outer to inner?
Crust, Mantle, Outer Core, Inner Core
(Can My Otter Interrupt)
What are the tectonic plates?
Huge slabs of rock that make up Earth's crust which are constantly moving and cause the continents to drift and things like volcanos, earthquakes, etc to form.
Why is it more likely for earthquakes and tsunamis to happen in Japan rather than New York?
Because Japan sits on a plate boundary, and when stress occurs there, it can cause an earthquake/tsunami
A _________________ is where the heavier plate sinks beneath the lighter plate.
Subduction Zone
Molten rock from deep in the mantle
Magma
What exactly is a plate boundary?
The place where 2 tectonic plates meet
The land mass which separated due to the plates moving (continental drift) is called
Pangea
Describe (the steps of) how an earthquake occurs...
The tectonic plates interact with each other (often at a subduction zone), this causes a lot of stress and suddenly releases seismic waves which cause vibrations through the ground, leading to potential destruction.
What happens at the plate boundary which forms a mid-ocean ridge?
The plates diverge/separate and magma from the mantle emerges, which forms an underwater mountain range
Another name for a plate boundary...
Fault
Describe the formation of a mid-ocean ridge
Two plates diverge, and molten rock from the mantle emerges from the seafloor in underwater volcanic eruptions. When the molten rock/lava cools, it forms an underwater mountain range.
