Inner Core, Crust, Lithosphere, Asthenosphere
Inner core, Outer Core, Mantle, Crust
Outer Core, Inner Core, Mantle, Crust
What is Pangea?
a fern that lives close to the equator
a large ice sheet
a supercontinent made of the present-day continents
Seafloor spreading is a process that...
Destroys oceanic crust
Occurs at the mid-ocean ridges
Causes continents to plow through the seafloor
Which is most likely to form along a convergent tectonic boundary?
a delta
an ocean basin
a mountain range
a valley
What happens at a transform plate boundary?
Plates move away from each other
Plates move toward each other
Plates slide past each other
In divergent plate boundary...
two plates separate
two continental plates collide
two plates slide past one another
What is the theory of plate tectonics?
Earth’s outer layer is made up of large, moving pieces called plates
Cracks in the Earth's crust cause volcanoes
The Earth was created by meteors crashing into each other
When oceanic and continental crust converge, the oceanic plate will dive beneath the continental plate. What best explains the results of this action?
The oceanic crust is moved upward by the radiation of heat
The oceanic crust will melt as it moves deeper in the earth.
The continental crust will form a mountain range.
The two crusts will form an ocean basin
Which layer of the Earth is liquid and composed mostly of iron and nickel?
inner core
crust
outer core
mantle
What are tectonic plates?
slabs of oceanic crust
slabs of continental crust
slabs of crust and upper mantle
What was the name of the theory that Alfred Wegener proposed explaining why the continents moved?
seafloor spreading
continental drift
land moving
rifting
The evidence to prove continental drift was discovered prior to Wegener's death?
True
False
Scientists understand that continents move because of the _________ moves underneath the ________
lithosphere and mantle
convection currents and magentism
asthenosphere and lithosphere
A region, known as the Ring of Fire, follows the border of the Pacific Ocean basin. Why do so many earthquakes and volcanoes occur in this region?
Transform boundaries completely surround this region of the Pacific Ocean
Only powerful convergent plates are located along the Ring of Fire.
Two plates are diverging in the center of the Pacific Ocean basin.
Numerous tectonic plate boundaries are located along the edges of this region.
The movement of Earth's plates results in changes in Earth's surface. Some of these changes occur very quickly, while others may take millions of years. Which of the following is most likely formed from a rapid change?
a mountain range
a mid-ocean ridge
a volcano
a valley
As new information is discovered, scientific theories are changed. Sometimes, old theories are revised. Why is this a necessary practice for science?
It ensures that the newest ideas are the ones used to develop medicines and important safety equipment.
New scientists need to get credit for their ideas or no one will go into science professions
Old theories are dependent on primitive technology that was flawed, so new technology must be used
The process allows for an increasingly accurate understanding of the world.
Mountains like the Himalayas in southern Asia form because these plate boundaries collide...
Divergent Plate Boundary
Convergent Plate Boundary
Transform Plate Boundary
