7.
Soil and water were heated for 10 minutes from a starting temperature of 20oC. After the heat lamp is turned off and removed from the area, how will the cooling rates of soil and water compare?
a)
The soil will cool faster because it has a lower specific heat.
b)
The soil will cool faster because it is a good reflector

13.
Why is the Oceanic Conveyor Belt also called the Thermohaline Circulation?
a)
Because it was discovered by Thermo Haline.
b)
Because it is driven by temperature and salt differences
c)
Because it flows at the surface and bottom of the ocean.
