Answer:
b. There is insufficient contrast in surface type (land vs. ocean) in the middle latitudes.
Explanation:
The sources of air masses can be produced or at very high latitudes because they can carry big amounts of air from the top of a mountain till the bottom by the differences of pressure and temperatures. This kind of air mass is called continental.
In the other hand, in a low latitude, the air coming from the sea, try to reach higher latitudes, again, by pressure and temperatures differences. These kind of air masses are called maritime.

Cloud droplets collide to form larger droplets in a process called <u>coalescence</u>
Answer: Option A
<u>Explanation:</u>
When the drop lets of the cloud which are present in the air bang into each other, the result is the formation of a bigger drop let of the cloud and this whole process is known as coalescence.
And such big drop lets are big enough in their size which can result in the rainfall in that region. The droplet should at least reach a size of 4 mm to result into rainfall and this collision is a fast process.
Answer:
The Sahara is dominated by two climatic regimes: a dry subtropical climate in the north and a dry tropical climate in the south. The dry subtropical climate is characterized by unusually high annual and diurnal temperature ranges, cold to cool winters and hot summers, and two precipitation maximums.

Explanation:
Answer:
Some cratons in Canada and Greenland shelter the oldest continental rocks in the world, about 4 billion years old. Other cratons in South Africa, Australia and Asia have continental rocks that are 3 billion years old. The oldest seafloor is comparatively very young, approximately 280 million years old.
