cloud

Answer 1

billions of tiny dropplets of ice and water and dust particles visible from the ground

Question 2

cold front

Answer 2

the leading edge of cold air mass. It occurs when a cold air mass pushes a warm air mass ahead of it.

Question 3

convection

Answer 3

the process by which heat moves efficiently through air or water

Question 4

convection current

Answer 4

a circulating flow of air or water resulting from temperature differences; also called convection cell

Question 5

land breeze

Answer 5

the flow of air from land to water (gets it’s name from the direction it is coming from)

Question 6

Occulded front

Answer 6

a boundry that occurs when both a col and a cool air mass collide with a warm air mass, which becomes trapped and lifted between them (the warm air is lifted and trapped in the middle of the two cooler air masses)

Question 7

Sea Breeze

Answer 7

the flow of air from water to land (gets it’s name from the direction it is coming from)

Question 8

Stationary front

Answer 8

A boundary that occurs when two air masses move closer to one another, but neither has enough fore to move the other; they both remain fixed in place

Question 9

Warm front

Answer 9

a boundary that occurs when a moving warm air mass overrides a cold air mass ahead of it.

Question 10

Weather front

Answer 10

A boundary that forms when air masses meet that have different temperature, pressure and humidity.

Question 11

Wind

Answer 11

moving part of the convection current
