(iii) In addition to direct measurements, relative sea surface temperatures can be inferred with radar measurements from satellites. Cold sea surface water will be further away from the satellite than warm sea surface water. Explain why this occurs.

The reason cold sea surface water will be further away from the satellite than warm sea surface water is because the satellites are placed a relatively fixed height. The waters levels however are not.

Explanation:

Whenever the climate heats up, sea water level rises because:

So, because the satellites are fixed but the water level is rising, the distance between the satellites and the warm sea surface water is reduced.

In contrast, as the climate gets cooler, water contracts and freezes up and cause the water level to shrink thus causing the satellite to be 'farther away' from the surface of the water.

hello!

let's go through all of these words' definitions.

u-shaped valley - where the valley curves down like a u shape

corrie - similar to the hole created at the top of a volcano when it erupts, it's almost like a dent in a mountain

pyramidal peak - a mountain where the peak is very sharp, such as the matterhorn.

arete - two valleys separated by a thin mountain range

i'm going to assume you know how to read a topographic map, but in case you don't, feel free to comment.

now, let's figure out which one's which:

a - seems to be a mountain range separating two valleys, with a mountain running from top center to bottom center and two valleys on either side. therefore, i'd consider this an arete.

b - it looks like a dent into the mountain, like what a corrie is.

c - looks to be a valley, with two steeper sides curving up around the bottom of the valley which has a river in it. i would consider this an u-shaped valley.

hope this !
