Question

When Scuba Steph got back to the beach, she sat in the sun. After a little while, she noticed that there was a white, powdery residue on the sleeve of her wetsuit. What is that?

A. Dust from the coral reef she must have accidentally hit
B. Salt left behind after water evaporated
C. Powdered sugar from the donut she had for breakfast

Answer 1

I think it is B. Salt left behind after water evaporated because in water, there is salt. When the sun appears, the water evaporates a little, causing the salt to expose!
