An illustration of how a convection current creates a wind, called a sea breeze, is provided. Which of the following best explains what creates this convection current?

• Salt in the ocean makes it more dense than the land, so its gravity pulls more on the air above it.

• During the day, the Sun’s energy heats up the land faster, which makes the air above it warmer.

• The rotation of Earth makes the air above it rotate, but not the same over land and water.

• During the day, Earth’s gravity creates a high pressure area over both the land and water.

The major patterns of movement of air and water on Earth are the result of –

• different densities of seawater and fresh water.

• diversity in the height of coastal landforms.

• uneven heating and the rotation of Earth.

• irregular durations of daytime and nighttime.

Why is solar energy considered renewable and clean?

• Because it is derived from ancient sunlight

• Because it does not produce any pollution

• Because it can be stored for later use

• Because it is abundant and never runs out

Where does the energy for toasting bread come from?
