Air density ________ the farther up in the atmosphere you travel.

• lowers

• rises

• stabilizes

• freezes

What helps the earth’s temperature stay stable?

• The chemical energy absorbed and stored.

• The nuclear energy absorbed and stored.

• The solar energy absorbed and stored.

• The electric solar energy absorbed and stored.

What causes wind to form, and explain the ways sea and land breezes form?

• Winds are formed by equal heating. Warm, dense air pushes underneath causing cool air to rise.

• Winds are formed by unequal heating. Cool, dense air pushes underneath causing warm air to rise.

• Winds are formed by unequal heating. Warm, dense air pushes underneath causing cool air to rise.

• Winds are formed by equal heating. Cool, dense air pushes underneath causing more cool air to rise.

Is it easier to breath at high altitudes or low altitudes?

• Higher because the air density and pressure is lower and particles are closer together.

• Lower because the air density and pressure is lower and particles are closer together.

• Lower because the air density and pressure is higher and particles are closer together.

• Higher because the air density and pressure is higher and particles are closer together.
