SCIENCE 10 LESSON 2.1-2.2

It is the planet's outer solid layer

• Inner Core

• Asthenosphere

• Lithospehere

• Mesospheric Mantle

It is a highly viscous, hotter, and ductile region of the upper mantle involved in plate tectonic movement and isostatic adjustment, lies beneath the lithosphere.

• Asthenosphere

• Lithosphere

• Crust

• Lower Mantle

It is the thinnest layer as it makes up only about one percent of Earth.

• Mantle

• Crust

• Inner Core

• Core

It is the most common element in the crust

• Sodium

• Magnesium

• Iron

• Oxygen

It is the final and innermost layer, which is divided into two parts

• Core

• Mantle

• Crust

• Lithosphere

It accounts for about 4% of the mantle-crust mass.

• Core

• Inner Core

• Outer Core

• Dynamo

It is in a solid state that is located in the planet's deepest region.

• Core

• Outer Core

• Inner Core

• Crust

This protects us from the harmful rays emitted by the sun.

• Geomagnetic Reversal

• Crust

• Greenhouse Gas

• Geomagnetic Field

This occurs when there is a change in the magnetic field of Earth.

• Flip

• Geomagnetic Reversal

• Geomagnetic Field

• Normal Polarity

This separates crust from mantle

• MOHO

• Asthenosphere

• Lithosphere

• Curves
