(E7) Weather Quiz Prep - Lessons 3 & 4

What is the FOURTH step when there is a large temperature difference between colliding air masses?

• A boundary called a front is created between the colliding air masses.

• The cold air wedges under the warm air mass.

• Cold air mass pushes (lifts) the unstable warm air mass up.

• Warm air transfers energy to the surrounding air and cools.
