What are the three types of plate boundaries?

Divergent plate boundary
Convergent plate boundary
Subduction plate boundary
Which type of plate boundary occurs when two plates collide and one is forced beneath the other?
Subduction plate boundary
Convergent plate boundary
Transform plate boundary
Divergent plate boundary
Which type of plate boundary occurs when two plates slide past each other horizontally?

What is the term for the shaking or trembling of the Earth's surface caused by the sudden release of energy in the Earth's crust?
ground shaking
tremor
seismic activity
earthquake
Which layers of the earth make up the lithosphere?
Upper mantle and crust
continental and oceanic crust
Mantle, crust, outer core
Inner core and outer core
Which best describes the relationship between depth into the earth and temperature/density/pressure?
As depth into the earth increases temperature, density, and pressure decrease.
As depth into the earth increases temperature, density, and pressure increase.
As depth into the earth decreases temperature, density, and pressure increase.
As depth into the earth increases temperature and density increases but pressure decreases.
What is the energy source for convection currents in the asthenosphere?
Geothermal heat
Heat from the sun that permeates through earth's crust
Heat from the core
Earth's magnetic field
Which type of crust is denser; continental crust or oceanic crust?
Continental crust
Oceanic Crust
Why does oceanic crust subduct below continental crust?
Continental crust is denser than oceanic crust
Oceanic crust is more drawn to earth's iron core
Oceanic crust is denser than continental crust
Oceanic crust is further below continental crust so it's the first to subduct
Where do volcanoes tend to form?
Hotter area's of the earth
Geothermal vents
Island chains
Subduction zones
Which of these is not a geological event due to the movement of tectonic plates?
Deltas forming
Volcanoes
Earthquakes
Mountain forming
Why do volcanoes form at subduction zones and not other boundaries?
Convergent boundaries produce infant volcanoes that are destroyed before they can release magma.
At subduction zones the dense oceanic crust melts, becomes less dense, and rises to the surface as hot magma
Transform boundaries are when tectonic plates slide past each other creating too much energy that would destroy volcano formation
Why would fossils of the same type of land animal be found on two continents separated by an ocean?
Early humans brought plant and animal specimens between continents
Over time the land animals evolved flippers, gills, and other aquatic body parts to swim to the other continent
The continents were once together in Pangea
The environments the fossils were found in are similar. Therefore they created the same types of animals.
Why does magma rise in convection currents when it's heated up and sink when it cools down?
When magma heats up it become less dense which causes it to rise.
When magma heats up it becomes attracted to the oceanic crust on the surface
When magma cool off it becomes more attracted to earth's core so it sinks
The area around the pacific plate where boundaries form is called...
death ring
fire zone
ring of fire
zone of fire
Why did other scientists have a hard time believing Wegener's theory of continental drift?
He could not explain how the continents moved
He didn't have enough evidence
His evidence was wrong
He didn't use the right technology to gather data
The Appalachian Mountains in the U.S. match up with a similar mountain range in Northern Europe. How does this support Wegener's theory of Continental Drift?
The similarities provide evidence that North America and Europe were connected when the mountains formed.
The similarities show that the continents must have been closer to the equator at some point in time.
This does not provide any evidence to support his theory.
