Layers of Earth
Which layer of the Earth is the thinnest?
What is the crust?
Most divergent boundaries lie under the world's oceans. Which of these is a process that occurs at divergent boundaries:
subduction of old crust
formation of new crust
OR plates slide past each other?
What is formation of new crust?
Scientists think continents were once a large single landmass that broke apart and then the continents slowly DRIFTED to their present locations. What is the name given to this hypothesis?
What is continental drift?
What happens at a convergent tectonic plate boundary?
What is two tectonic plates collide with one another, causing subduction and or mountain building?
Do volcanoes alway erupt quickly and by throwing magma into the air?
What is no some volcanoes erupt slowly?
How is the outer core different than the inner core?
What is the outer core is liquid and the inner core is solid?
Subduction is one plate pushing underneath another plate. If an oceanic plate and a continental plate collide, which one will push underneath the other one and why.
What is the oceanic plate will push under because it is denser?
Define epicenter.
What is the position on the Earth's surface where an earthquake begins.
What are most volcanoes found along?
What is plate boundaries.
What is it called when there is a sudden release of the earths crust that causes vibrations?
What is Earthquake?
When an oceanic plate and a continental plate collide, what is formed on the continental plate.
What are mountains (probably volcanic arc)?
An Earthquake in City A registers 5.6, City B 7.8, and City C 6.8. Which city had the strongest earthquake?
What is City B?
What is the name of a volcano that is found away from a plate boundary
What is Hot spot?
What is it called when there is an opening in the earths crust which molten rock erupts through?.
What is a Volcano?
Name the three types of plate boundaries.
What is Convergent, Divergent, and Transform?
What are aftershocks?
What are smaller tremors that can occur at any time for months after an earthquake as the pressure is gradually released?
What is in the ocean?
What are ocean waves called when they are caused by a earthquake or underwater volcano?
What is tsunamis?
Describe a divergent boundary.
What is the plates seperate?
How do continents move?
What is continents move along with the plate they are part of? Convergent boundaries/Subduction zones recycle old crust while divergent boundaries create new crust
Name two effects of an Earthquake.
What are tsunamis, ground shaking, building to sway and fall. water pipes break, people can get hurt, tunnels to collapse, fuel/gas lines can break.
Name two effects of volcanoes.
What are clouds of hot ash, destruction of crops/livestock, Towns have been destroyed by ash/lava, carbon dioxide gas poisoning, Ash can block the sun and cool temperatures for years ?
