Continental crust is primarily made out of , which is a type of rock. 5 points) a) granite; sedimentary b) basalt; igneous c) granite, igneous d) basalt; metamorphic

Explanation / Answer

1.C

This is so because more the number of cloud droplets mean less size of the individual droplet than the cloud with less number. thus albedo will be more and chances of precipitation will reduce.

2.B

Evaporation in subtropics is more than the equator, similarly, precipitation in subtropics is less. Thus they will have more salinity.

3.D

Photic zone is a nutrient minimum zone due to rich ecology.

4. A and D

Salinity and temperature both control the density of the sea water.

5.C
