Which mineral makes up most of the surface of

the Moon?

Are basaltic magmas on the surface of Earth more or less likely to

contain olivine crystals than those on Mars?

On which Solar System body do you think that olivine would settle slowest from basaltic magma?

On any rocky planet, which of the following happens within a crystallising basaltic magma chamber?

On which Solar System body do you think that an iron metal globule would sink fastest from basaltic magma?

What is the surface water density in the Mediterranean Sea bounded by 32^oN to 35^oN & 25^oE to 34^oE?

Ensure your answer is entered as in-situ densities (sigma), which is the calculated density minus 1000, and please report your answer to two decimal places.

Given that you know the densities of water from the two main regions where surface waters sink (look at the map of ocean thermohaline circulation in your lecture notes for the locations of these areas), you should be able to make an estimate of the potential density (i.e., the density the water would have if was brought to the surface) of the typical ocean interior (above the bottom waters, but below the surface waters).

Which TWO of the following answers are NOT correct estimates of the potential density?

Note: Selecting a wrong answer (an estimate that is actually correct) will lose marks.

What

is the typical direction of the Trade Winds along the Equator?

Match three of the Atlantic water masses (Antarctic, North Atlantic, Sub-Tropical Atlantic) to their vertical position as they would occur in a single water column. 1 = surface and 3 = bottom

In

order to form a tropical cyclone, which of the following ingredients are

required?
