Deep on the ocean floor - specifically in the middle of the Atlantic Ocean - tectonic plates are moving apart.

As the plates move apart at divergent oceanic boundaries, magma is pushing its way up from below, trying to escape!!!!

As it escapes, it is cooled quickly by the water, and forms new crust on the ocean floor.

It also oozes upwards, forming mountains!!! The longest mountain chain in the world is the Mid-Atlantic Ridge at the bottom of the Atlantic Ocean.

We measure the magnitude (intensity) of earthquakes using the Richter Scale.

Compositional layers are based on what the layers are "composed" of - which means what they are made of.

The crust is the thinnest, and it is made of silicates.

The mantle is the thickest, also made of silicates.

The core is wider than the mantle is thick, and is made of iron & nickel.

These layers formed because the heaviest - densest - material was pulled to the center by gravity. The least dense material rose to the surface and cooled into rock.

The mechanical layers are grouped based on their movement. Remember, everything is boiling and churning inside the Earth, which affects the surface too!

The lithosphere is being pushed around - pushed against itself, past itself, or even under itself until it melts back down.

The asthenosphere is like putty or gum, being pushed along by the convection currents below it, and allowing the lithosphere to slide around on top of it.

The mesosphere is in the middle, and this is where most of the action happens - there's just enough heat but not too much pressure - for some real movement here.

We call this movement "convection currents" as the hottest material rushes to the surface before cooling slightly and being dragged back down.

The outer core is molten metal with currents of heat rippling through it, generating a magnetic field for the Earth!!!

The inner core is molten metal too, but it's under so much pressure from the rest of the Earth pressing down on it, it can't move at all, it just gets really hot and helps the rest keep moving!

Geology is the study of the rocks and minerals on Earth's surface. We'll study the layers of the Earth, the tectonic plates and their movements, as well as the seismic activities - such as volcanoes & earthquakes - that result from this movement. We'll also learn about the Rock Cycle, landforms, and weathering, erosion, & deposition.
