Earth's Layers and Earth's Atmosphere Quiz

Lower part of the mantle. Convection currents occur here. It is a solid.

• inner core
• mantle/mesosphere
• lithosphere
• crust

It is a solid and consistent of Earth's crust and upper mantle. Tectonic plates are located here. Oxygen is 46% silicon 28% aluminum 8%.

• inner core
• mantle/mesosphere
• lithosphere
• crust

Upper part of the mantle. Semi-solid like jelly layer in which plates move.

• mantle/mesosphere
• crust
• inner core
• asthenosphere

Most dense layer. Mostly composed of iron. Is the hottest layer but because there is so much pressure on this layer it is solid.

• mantle/mesosphere
• crust
• inner core
• asthenosphere

Combination of iron and nickel. It is a liquid. Electrical currents generate Earth's magnetic field.

• mantle/mesosphere
• outer core
• inner core
• asthenosphere

Thinnest layer buy largest layer. The temperature is very cold, this is where space is located. Least pressure and least density.

• Thermosphere
• Troposphere
• Exosphere
• Stratosphere

Thinnest and coolest layer. Two types of crust: continental crust-les dense. oceanic crust-more dense.

• mantle/mesosphere
• crust
• inner core
• asthenosphere

As the altitude increases, the temperature increases due to the ozone layer. Free of weather and clouds.

• Thermosphere
• Troposphere
• mesosphere
• Stratosphere

All weather occurs here, 21% oxygen which makes life possible. Most dense layer. 80% of the atmosphere's mass.

• Thermosphere
• Troposphere
• mesosphere
• exosphere
