Layers, Donkey!
V for Volcano
100

This Sphere contains all the living organisms on the earth.

What is the Biosphere?

100

This is the mathematical formula for density.

What is D=m/V?

100

This is the thinnest and coolest layer of the earth.

What is the crust?

100

This substance, ejected from a volcano, can block out the sun and cause global temperatures to fall.

What is volcanic dust/ash?

200

This sphere can also be considered a part of earth's hydrosphere.

What is the cryosphere?

200

This substance has a density of 1 g/ml.

What is water?

200

This is the only completely liquid layer of the earth.

What is the outer core?

200

This town's eruption was the first eruption to be called a volcano.

What is Pompeii?

300

This sphere is composed mostly of carbon, silica, and other minerals.

What is the lithosphere?

300

This is the density for a block of wood that weighs 3.3 grams and takes up 4.4 ml of volume.

0.75 g/ml

300

This sub-layer of the mantle is what allows tectonic plates to move.

What is the asthenosphere?

300

This eruption is though to have nearly wiped out humanity and left the human species with approximately 3,000 individuals.

What is the Toba eruption?

400

This sphere is where most greenhouse gases settle which affects the global climate.

What is the atmosphere?

400

A coin that floats in alcohol (D= 0.92 g/ml) should do this is water?

What is float?

400

This protective shield around earth is formed by the outer core spinning around the inner core of earth.

What is the magnetosphere?

400

This fast moving cloud of hot ash, steam, and molten materials can travel as fast as a speeding car when being ejected from an eruption.

What is a pyroclastic flow?

500

97% of the hydrophere is made of this.

What is salt water?

500

Fluids that become less dense with heat will begin to rise in this form of heat transfer.

What is convection?

500

Magma moving up through fissures in the ocean floor creates more of this layer?

What is the oceanic crust?

500

Magma tends to form quickly and generates more pressure when in the presence of these two substances.

What are water and carbon dioxide?
