Heat Transfer
The transfer of heat through space is called this.
What is radiation?
The major belt of volcanoes that rim the Pacific Ocean is called this.
What is the Ring of Fire?
The evidence of these ancient organisms that were preserved in rock helped Wegener come up with his hypothesis of continental drift.
What is a fossil?
It was the use of this invention that scientists discovered why the continents were moving.
What is sonar?
These are what we call breaks in the Earth's crust.
What are faults?
When you touch a hot plate, the transfer of heat from the plate to your hand is called this.
What is conduction?
This is an area where material from deep within Earth's mantle rises through the crust and melts to form magma.
What is a hot spot?
This was the name Wegener gave the supercontinent he believed was connected 300 million years ago.
What is Pangaea?
This is where molten material rises from the mantle adds more crust.
What is the Mid-ocean ridge
A collision between two pieces of continental crust at a converging boundary produces this.
What is a mountain range?
The heat transfer that happens by the movement of a fluid is called this.
What is convection?
Volcanoes that form along a mid-ocean ridge occur at this type of boundary.
What is a diverging plate boundary?
This theory was eventually disproved even though there was much evidence for it.
What was the theory of continental drift?
This is why old oceanic crust is more dense than new oceanic crust.
Because it is cooler.
When two plates slip past each other, you get this type of boundary.
What is a transform boundary?
When making soup, the hot soup nears the surface and begins to cool, but then it sinks. This constant motion of soup is called this type of heat transfer.
What is convection current?
A string of islands that can form from the collision of two oceanic plates is known as this.
These were a few reasons why Wegener believed the continents had been joined.
What are the shapes of the coasts, fossils, and tropical plants in the Arctic Ocean?
This is the process by which the ocean floor sinks back into the mantle again.
What is subduction?
When continental plates pull apart at a divergent boundary on land, this forms.
What is a rift valley?
In the motion of convection currents, it is the force of this that sets them moving.
What is gravity?
This is the location where you would most likely find volcanoes.
What is along mid-ocean ridges and where a plate is subducted?
What was Alfred?
When the ocean floor sinks back into the mantle again it forms this type of ocean trench.
What is a deep-ocean trench?
The geological theory that states that pieces of Earth's lithosphere are in constant, slow motion is the theory of this.
What is the theory of plate tectonics?
