True

False

 

6 Cold front

Explanation:Cold fronts occur when heavy cold air displaces lighter warm air, pushing it upward. Cumulus clouds are the most common cloud types that are produced by cold fronts. They often grow into cumulonimbus clouds, which produce thunderstorms

7 MP

Explanation: Maritime polar (mP) air masses are cool, moist, and unstable.

Some maritime polar air masses originate as continental polar air masses over Asia and move westward over the Pacific, collecting warmth and moisture from the ocean. Some mP air masses originate from the North Atlantic and move southwestward toward the Northeast States. The latter air mass generally is colder and drier than the mP off of the Pacific.

8.Insolation Variation

Explanation: Insolation can be described as the incoming solar energy that reaches the Earth's atmosphere and surface. This energy is released from the sun in short waves and travels through space until it reaches the earth's outer atmosphere (the Thermosphere) from where it can either be absorbed, reflected or pass directly through to the Earth's surface. Milankovitch cycles describe the collective effects of changes in the Earth's movements on its climate over thousands of years.

9.Fast moving polar anticyclone

Explanation: Siberian Express is a meteorological term in the United States describing the arrival of an extremely cold air mass of Siberian origins. It specifically refers to an origin in Siberia. The term is most commonly employed by the news media when such a frigid air mass moves into the northern plains or upper Midwest. 

10 TRUE

Explanation: The Fujita scale, or Fujita-Pearson scale, is a scale for rating tornado intensity, based primarily on the damage tornadoes inflict on human-built structures and vegetation.
