Heat Transfer
___________ is the type of heat transfer that requires no direct contact.
What is radiation
__________ is the thinnest layer of the earth.
What is the crust
____________ creates earth's magnetic field.
What is the outer core
Where is the crust generally the thinnest?
A. Under continental crust
B. Under oceanic crust
C. They are the same thickness
B. Under oceanic crust
When mantle rock is denser, it will ___.
What is sink towards the core
___________ is the type of heat transfer that requires direct contact.
___________ is the hottest layer of the earth.
What is the core
Much of the planet's ___ consists of magma. This magma can push through holes or cracks in the crust, causing a volcanic eruption. When magma flows or erupts onto Earth's surface, it is called lava. Like solid rock, magma is a mixture of minerals.
What is the mantle
Where is the largest borehole in the world located?
Russia
As the mantle heats up, what happens to the movement of the particles?
What is they move faster
________________ is the type of heat transfer that happens when fluids flow causing heat to move from one part of the fluid to another.
What is convection
____________ is the thickest major layer of the earth.
What is the mantle
The ___ is the innermost layer of the Earth.
What is the inner core
What force causes the more dense material to sink within earth?
gravity
What is the heat source that causes the Earth’s mantle to get hot?
What is heat from the core
When we stand in front of a fireplace or a campfire, we can feel the heat moving outwards towards us, without actually anything. This is an example of ________.
What is radiation
Which layer consists of both oceanic AND continental?
What is the crust
The correct order of the Earth’s layers starting from the OUTSIDE going inward is ___.
What is...
Crust
Mantle
Outer Core
Inner Core
What layer moves like plastic or toothpaste?
What is the asthenosphere
How does the mantle rock change as it moves away from the core?
What is it begins to cool, and the movement starts to slow down
________________ is the type of heat transfer that occurs in the asthenosphere AND the outer core.
What is convection
The ___ is referred to as plastic-like because the material moves about in more of a fluid way that mimics flexible plastic. It has also been compared to the way toothpaste flows out of a tube when squeezed.
What is the asthenosphere
As you travel deeper into the earth, what 2 things increase?
What are temperature and pressure
Why can’t we send equipment deep down to learn more about the interior of Earth?
What is the temperature and pressure would crush and destroy equipment
What happens to the density of heated mantle rock? And why?
What is the density decreases because the particles spread out when they are heated, causing the mantle to rise
