Answer to question 4

The areas of water in this image are mostly a speckled grey tone, but with large sections of black. These black areas are:

1. Top
2. Bottom
3. Right
4. Left

The answer is D.

A. No.

You're just guessing, aren't you?

B. No.

There is absolutely no evidence for this!

C. No.

Another wild guess!

D. Yes.

Evidence for this comes from a number of image features. At the top, as the hills are illuminated by the radar, they show a brighter reflection from the radar-facing side which are the left side slopes. At the bottom right are two long piers jutting out into the water. These piers show a radar shadow to their right, which indicates radar illumination from the left.

Did You Know?

1. The linear structures seen here are called internal waves.
2. Ferries on their way to and from the islands can be seen on the water.
3. These piers are the ferry (left) and bulk cargo (right) terminals at Tsawwassen, BC.
