Which of the following statements is true about Earth's inner core?
The inner core is the densest layer of the Earth
The inner core is the thickest layer inside the Earth
the inner core is made up to molten rock and Mg
The inner core is the coolest section the Earth's interior
2
Which of the following pieces of evidence does not support continental drift?
Volcanoes appear to originate from a single spot
Similar Fossils
South America and Africa coastlines appear to fit together
Paleoglaciation
3
The convection currents that drive continental drift are located in the
Asthnoshphere
Lithosphere
Outer Core
Mantle
4
Tectonic plates
Are denser than the mantle so cannot sink into
are made of lithosphere and upper mantle
can be several thousand kilometers thick
Are made up to lithosphere alone
5
The inner core of the Earth is about 6000⁰C. It stays solid because
Extreme pressure
The currents in the outer core
It's magnetic field
Its rotation
6
At a mid-ocean ridge like the mid-Atlantic ridge plates are
diverging
converging
subducting
magnetically reversing
7
Divergent plate boundaries are responsible for forming
convection currents
ocean trenches
Mid-ocean ridges
subduction zones
8
All of the following are associated with a subduction zone except
Lihosphere
Ridge push
Trenches
Slab Pull
9
Paleomagnetism was discovered
At the bottom of the deep trenches
From changes in migration patterns of the birds
In the vertical layers of the oceanic crust at ocean ridges
At the north and south poles of the Earth
10
Convection currents result because of
The changing density of the mantle's layers due to heating
The movement of divergent plates dragging magma to surface
Surface volcanoes drawing magma up through the crust.
The changing thickness of Earth's interior
11
