Sphere and Loathing
This Sphere contains all the living organisms on the earth.
What is the Biosphere?
This is the mathematical formula for density.
What is D=m/V?
This is the thinnest and coolest layer of the earth.
What is the crust?
This substance, ejected from a volcano, can block out the sun and cause global temperatures to fall.
What is volcanic dust/ash?
This sphere can also be considered a part of earth's hydrosphere.
What is the cryosphere?
This substance has a density of 1 g/ml.
What is water?
This is the only completely liquid layer of the earth.
What is the outer core?
This town's eruption was the first eruption to be called a volcano.
What is Pompeii?
This sphere is composed mostly of carbon, silica, and other minerals.
What is the lithosphere?
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
This sub-layer of the mantle is what allows tectonic plates to move.
What is the asthenosphere?
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?
This sphere is where most greenhouse gases settle which affects the global climate.
What is the atmosphere?
A coin that floats in alcohol (D= 0.92 g/ml) should do this is water?
What is float?
This protective shield around earth is formed by the outer core spinning around the inner core of earth.
What is the magnetosphere?
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?
97% of the hydrophere is made of this.
What is salt water?
Fluids that become less dense with heat will begin to rise in this form of heat transfer.
What is convection?
Magma moving up through fissures in the ocean floor creates more of this layer?
What is the oceanic crust?
Magma tends to form quickly and generates more pressure when in the presence of these two substances.
What are water and carbon dioxide?
