What is it called when two plate boundaries go away from each other?
Divergent plate boundaries
Which sphere talks about all liquid water on Earth?
Hydrosphere
Which layer of earth is semi-solid and the thickest layer?
The mantle.
The Ring of Fire would have what type of major geographical feature?
Volcanoes
Which scientist came up with the hypothesis of continental drift?
Alfred Wegener
Which of the following is not a plate boundary?
A) Divergent
B) Convergent
C) Transform
D) Horizontal
D) Horizontal
What sphere is all living organisms on Earth?
Biosphere
Why is the inner core solid and not liquid?
The temperature of the inner core would cause it to be liquid but because of the intense pressure from the force of gravity, it becomes solid metal.
Along convergent boundaries, what type of natural disaster would indicate a collision?
Earthquakes
What evidence could Wegener not support his hypothesis with?
The motion of how the continents moved.
The process of seafloor spreading occurs from divergent boundaries. What type of landform is made on the ocean floor from this?
Mid-Ocean Ridges
What spheres are a hurricane a part of?
Hydrosphere, geosphere, and biosphere
As you get closer to the center of the Earth, what happens to the temperature and pressure?
It increases.
How would mountains form?
Two continental crusts colliding at a convergent boundary.
What were the three types of clues Wegener had for continental drift?
Fossil, rock, and climate
What type of landforms can be made from convergent boundaries?
Mountains and Volcanoes
What two spheres did continental drift mainly affect?
Geosphere and Biosphere
What are two names for the mantle? One is the upper mantle, and one is the lower mantle.
Upper mantle is the asthenosphere and the lower sphere is the lithosphere.
How did the Hawaii islands form?
From underwater volcanic eruptions.
