a)
be warmer

2.
Which of these best describes how heat is moved around in Earth’s oceans?
a)
Warm winds blow over the oceans from land, causing the ocean water to warm up.
b)

Even heating of Earth’s surface causes ocean water to rise and sink, creating convection currents.
b)
Uneven heating of Earth’s surface causes ocean water to rise and sink, creating conduction currents.
c)
Uneven heating of Earth’s surface causes ocean water to rise and sink, creating convection currents.
