A feature that can cause volcanoes in the middle of plates is a
convergent collision boundary
hotspot
convergent subduction boundary
mid-ocean ridge
In a hotspot chain
all volcanoes are active
only one volcano is active
a few random volcanoes are active
there are no volcanoes, only earthquakes
A hotspot creates a volcano chain when
the hotspot moves but the plate stays still
the hotspot stays still but the plate moves
the hotspot and the plate move in opposite directions
convection in the mantle wears a hole in the crust
A volcano in a hotspot chain goes extinct when
The mantle stops producing magma
The plate moves and the volcano moves away from the hotspot
The volcanic rock plugs the source of the magma
The hotspot moves away from the volcano.
Geologist can tell the direction of plate movement by looking at hotspot chains.
True
False
What happens to the older volcanoes in a hotspot chain?
The continue to increase in size as the volcanoes erupt.
They give advice about life to the younger volcanoes
They explode when the pressure becomes too great.
They become smaller because of weathering and erosion
What can we learn about the Pacific plate by looking at the seamounts from Hawaii?
The direction of the plate movement has changed
Hawaii is only about 400,000 years old
It is made of granite
The Pacific ocean is shrinking
Hotspot volcano chains have volcanoes that
are all the same size
get smaller as they get farther from the hotspot.
get smaller as they get closer to the hotspot
In this hotspot chain, which way is the plate moving?
toward the northeast
toward the southeast
toward the northwest
toward the southwest
In this hotspot chain, which way is the plate moving?
To the right -->

What is a caldera?
Where witches brew their potions
an active volcano
a large, extinct, volcanic crater
a magma chamber
Hotspots form because...
magma is pushed to the surface at a plate boundary.
a mantle plume weakens Earth's crust.
water is pushed up to Earth's surface
a mantle plume strengthens Earth's crust.
In the wax volcano model, the water represented
the ocean
the mantle
a layer of rock
What is a hotspot?
Hot parts of the crust
Hot part of the mantle
Hot part of the lithosphere
Cold area on the crust
How does a hot spot create a volcano?
The pressure from below the earth forces the magma to the surface
it is formed when a subucting plate goes into the mantle and melts
It melts the bottom layer of the crust and the magma moves up to the surface.
it pushes magma from the Earth's core to the surface of the Earth.
