EARTH SCIENCE (GROUP 3)

It is a phenomenon observed in the geological record that was significant in supporting the theory of continental drift.

• MOUNTAIN RANGES

It acts as Earth's heat engine.

It is composed of a great variety of igneous, metamorphic, and sedimentary rocks, like Granite and Basalt. This plays a central role in plate tectonics, which involves the movement of tectonic plates.

• OCEANIC CRUST

• CONTINENTAL CRUST

• CRUST

• MANTLE

Together the crust and the upper mantle form a fixed shell called the ___________

He determined how oceanic mountain ranges, called mid-ocean ridges, are fundamental to the tectonic movement that results in the drift of continents.

What process generates the Earth's magnetic field through the movement of molten iron and nickel in the outer core?

Here, the temperatures are so high that in places, the rock that makes it up melts into liquid.

• MESOSPHERE

• ASTHENOSPHERE

• INNER CORE

• LITHOSPHERE

This existed during the late Paleozoic and early Mesozoic eras (335 to 175 million years ago)

It plays a vital role in generating the magnetic shield that protects our planet from harmful solar wind—streams of radiation from the Sun—and makes Earth habitable.

• CONTINENTAL CRUST

• LITHOSPHERE

• CORE

When different plates converge, the plate with oceanic lithosphere will buckle beneath the continental plate, and sink into the hot asthenosphere. This process is called _________
