_________ is the lifting of depressed rock by magma under the surface and ________ is the sinking of heavy rock into the earth.
Bands of magnetic material in the sea floor that have opposite poles, or exhibit magnetic reversal, can provide evidence for sea floor spreading.
The _______________ contains the asthenosphere and the lower mantle.
Scientists follow seismic waves to locate the epicenter.
The mantle in the Earth continually heats up and cools down using convection currents.
___________ are formed at divergent and converging boundaries.
Divergent boundaries, normal faults and slope are land features which result from stretching the Earth’s crust. Reverse fault jagged cliffs and convergent boundaries are features which result from folding the Earth’s crust. Please select the best answer from the choices provided
Compare the heating in the mantle to a cooking pot of soup.
A pot of soup heated from below develops convection currents: warmer, less-dense soup rises and cooler, denser soup sinks. In the mantle, heated rock slowly rises and cooler rock sinks, creating currents that transfer heat and help move tectonic plates.
