Layers of the Earth
What are the 3 layers of the Earth?
crust, mantle, core
What is the Richter scale used for?
to measure the intensity of earthquakes
What was the name of the guy who came up with the theory of plate tectonics
Alfred Wegener (I will also accept just the last name)
give an example of a landform that convergent boundaries produce.
mountains, volcanoes, islands (I only need 1 of these)
What are the two types of cores called? Do they move in the same direction as the rest of the Earth?
inner core & outer core. No, they do not.
What are convection currents?
the circular heat flow of the mantle
What is the theory of plate tectonics
The Earth's crust is made up of rigid plates that move slowly over time.
What is a subduction zone?
When one plate slides underneath another one
What are the two types of crusts called?
Continental crust & oceanic crust
As you go deeper into the Earth, temperature ______________ and pressure _____________.
(increase or decrease?)
temperature and pressure both increase
In what direction do convergent boundaries move in.
The plates move together; they converge; ---><---
In what direction do the plates move in divergent boundaries?
they move away; apart; they diverge; <--- --->
True or False: the lithosphere includes both the crust and the uppermost part of the mantle
TRUE
give an example of a country, state, or region that rests on a fault line. What natural disaster occurs on these lines?
Japan; California; Mexico, Russia, Canada, Peru, Papua New Guinea, Indonesia, Taiwan, Philippines, Guatemala. Earthquakes happen on fault lines.
In what direction do the plates move in transform boundaries?
They slide against each other; ^v
What landform is created in a divergent boundary?
mid-ocean ridge
What are all the parts of the mantle?
Asthenosphere, lithosphere, upper mantle, lower mantle
what's my name
Mr. Jimenez. He-men-ez. (not Jiminez, Hernandez, Jimendez, Thomas, Riddick, Wright)
Give at least one example of a landform that transform boundaries produce.
linear valleys, small ponds, deep trenches, ridges, stream beds split in half, any landmark where the land looks like it got cut in half.
What are the 3 forces associated with plate boundaries and which boundary applies which force?
compression = convergent, tension = divergent, shear = transform
