When the early Earth began to have molten rock, layers formed because of their _____________.
shapes
densities
water content
No layers formed
As you travel from the inner core to the crust, how would temperature, pressure and density of the material change?
They would all increase
They would all decrease
Nothing, the layers are made of the same material throughout
Temperature would decrease, but pressure and density would increase
The mantle of Earth is made of a plastic like material that when it's heated, the material rises, cools, sinks and is then re-heated. This constant flow of a fluid is called __________.
a conduction current
a hot spot
a volcanic eruption
a convection current
Which layer does the lithosphere (the outer most layer plus the crust) float on top of?
the crust
inner core
asthenosphere
outer core
One of the deepest boreholes ever drilled was the Kola Superdeep Borehole located in Russia. It's depth is approximately 12 Km. To reach the center of Earth, we would need to drill over 6,000 Km. How do scientists study the deepest part of Earth if we've only drilled a fraction of the way through the crust?
By sending humans directly into the inner core
By visiting deep mines that go deep into the inner core
Sending robots deep into the inner core
By recording and studying seismic waves (earthquake P and S waves)
