Question 1
1.
What gave rise to Earths heat because of its impact into Earth?
Question 2
2.
What gave rise to Earths heat due to radioactive decay?
Question 3
3.
What gave rise to Earths heat because of layers upon layers?
Question 4
4.
What do we think is within the Earth's core that makes it so hot?
radioactive elements are dense, and dense materials traveled down to Earth's center
the pressure from the rocks above the core make it super cold
Question 5
5.
In a cave, the temperature is typically cooler than on the surface of the Earth. At what depth does the temperature begin to increase?
Question 6
6.
If the Earth is not a hot as it was, to what location did all the heat escape to?
Question 7
7.
Describe, using your own words, how the magnetic field around Earth is created.
Question 8
8.
Why does it matter that we study the Earths' magnetic field?
Question 9
9.
What causes the North Pole to 'wander'?
Question 10
10.
What do you think would be the first sign that something was off with the magnetic field?
the amount of solar radiation would decrease
the sun wouldn't feel as 'hot' as it does normally
there would be a lot of aurora borealis' all over the globe
the northern lights would barely be visible
thousands of hamsters running inside the planet
movement of lava around the Earth's mantel can cause friction which makes it more hot
the meteorite impact that killed all of the dinosaurs went into the Earth so far that it became the core of our planet
radioactive isotopes from the earths inner core
outer core is a liquid, and liquids flow can change
pressure from the atmosphere
the inner core is a solid, and solids can change
it is trying to get to the 'correct' spot
magnetic fields change randomly sometimes
