100
The hottest layer of the earth.
What is the core?
100
Plates come together at this type of boundary.
What is a convergent boundary?
100
The two categories of seismic waves.
What are body waves and surface waves?
100
These two layers of the atmosphere are thermally stable.
What are the stratosphere and thermosphere?
100
Air responds in this way to differences in pressure.
What is the flow of air from high to low pressure?
200
The upper, plastic part of the mantle.
What is the asthenosphere?
200
Why is volcanism more common at the convergence of ocean and continental crust, and less common at the convergence of two continental crusts?
Crust subducted at an ocean-continent boundary contains water. This produces low density magma that rises and forms volcanoes.
200
These types of seismic waves are the first and second to arrive at seismic stations, respectively.
What are P- and S-waves?
200
This substance, which blocks UV light, is found in the stratosphere.
What is ozone?
200
Rising air encounters lower pressures, allowing it to expand and experience this type of temperature change.
What is adiabatic cooling?
300
The layer of the earth that is above the local melting point.
What is the outer core?
300
Ocean trenches form as a result of this process.
What is subduction?
300
Data from two seismic stations can narrow down the determination of an earthquake epicenter to this number of possible locations.
What is two?
300
Two layers of the atmosphere are unstable, producing clouds and winds. This is the uppermost of the two.
What is the mesosphere?
300
The three ingredients needed for cloud formation.
What are water, temperature decrease, and condensation nuclei?
400
Two layers in which convection occurs.
What are the mantle and the outer core?
400
What pattern in crustal magnetic anomalies would you expect to find on a planet that has diverging tectonic plates and global magnetic field that periodically changes direction?
Stripes of alternating magnetic fields that are parallel to, and symmetrical about, that boundary.
400
On a nomogram, the magnitude of an earthquake is determined by drawing a line between measured values of these two quantities.
What are epicenter distance and largest S-wave amplitude?
400
Surface winds converge at, or near, the equator, for this reason.
The low pressure caused by rising hot air.
400
Mars has only one large-scale atmospheric convection cell in each hemisphere (as opposed to three for the earth). Why does this difference occur, given that Mars and Earth have approximately the same rotational period?
The velocity of the Martian surface is lower because it's a smaller planet. The Coriolis Effect is therefore weaker, and air can travel farther north or south before being deflected.
500
The outer core is ultimately responsible for this display of light in the night sky at high latitudes.
What is the aurora?
500
Mercury does not have plate tectonics for this reason.
Mercury is small, and therefore not hot enough to produce mantle convection and plate motion.
500
What broad conclusion can you draw about the location of an earthquake relative to your seismic station, if you do not receive S-waves from the quake?
The earthquake must be on the other side of the earth.
500
The space exploration industry declares the atmosphere to end, and space to begin, at an altitude of 100 km. What is wrong with the logic behind this declaration?
There is no well-defined edge of space (top of atmosphere).
500
In an infrared satellite image, India is light grey, while Australia is dark grey. Which location is likely to experience monsoon rainfall in the coming weeks, and why?
Australia. Dark grey in infrared images indicates warm temperatures. It is therefore southern summer, and time for monsoon rain.
