In Which Layer Does Meteors Burn Up In?

The exosphere is the most ____ layer of our atmosphere

In The Stratopshere What Is The Important Layer We Find which protects us from harmful UV sunlight

• atmospheric layer

• crust

• ozone layer

The exosphere has gases like ___ and ____, but they are very spread out.

• Helium and nitrogen

• oxygen and nitrogen

• hydrogen and helium

• All of the above

Choose the correct response that describes the correct states of matter of the Inner Core, Outer Core, and the Mantle

• Inner Core = Solid; Outer Core = Semi-solid; Mantle = Liquid

• Inner Core = Solid; Outer Core = Liquid; Mantle = Semi-solid

• Inner Core = Liquid ; Outer Core = Semi-solid; Mantle = Solid

• Inner Core = Semi-solid; Outer Core = Solid; Mantle = Liquid

What mistake has Kindra already made in building her model?

• She put the inner core in the wrong location.

• She has incorrectly marked the outer core as a liquid.

• She put the outer core in the wrong location.

• She has incorrectly marked the inner core as a gas.

Determine the correct description of Layers C and G.

• Layer C is the crust and is solid while Layer G is the mantle and is liquid in nature.

• Layer C is the Asthenosphere and is plastic-like while Layer G is the Lithosphere and is solid in nature.

• Layer C is the Lithosphere and is solid while Layer G is the Asthenosphere and is plastic-like in nature.

• Layer C is the mantle and is semi-solid while Layer G is the Lithosphere and is plastic-like in nature.

Identify the layer that contains convection currents and has direct impact on tectonic plate movement.

• Layer G

• Layer C

• Layer F

• Layer D

Layers A and B are both layers of the crust. Determine the correct descriptions of Layer A and Layer B.

• Layer A is the Continental crust and is less dense than Layer B because it is made up of mainly silicates. Layer B is the Oceanic crust and is more dense because it is made up of mainly basalt, iron, and magnesium.

• Layer A is the Continental crust and Layer B is the Oceanic crust. Their densities are equal because the elements inside of their layers are continuously mixed up due to convection current movements.

• Layer A is the Oceanic crust and Layer B is the Continental crust. They are made up of different elements therefore their densities cannot be compared.

• Layer A is the Oceanic crust and is more dense than Layer B because it is thicker in size. Layer B is the Continental crust and less dense because it is smaller in size.
