How are snow and Rain formation similar ??

Answers

Answer:

rain is formed by vapourisation of water from earth surface

but snow is formed by solidification of that vapourised water

hope it will help you

Answer:

Most precipitation is rain. Snow, hail, sleet, and fog are examples. When water droplets freeze into ice crystals in cold air, snow is formed. Water vapor collects on the crystal, becoming heavier and falling from the sky. As the ice crystal falls, it may contact warmer air, causing it to melt. As ice crystals melt, they bond together to form flakes. This makes a snowflake.

Why is so much of the Middle East in green on the map even though it is surrounded by major bodies of water?

Answers

Answer:

The Sahara desert is the third largest desert of the Planet (after Antarctica and the Arctic) and it takes all the north of the African continent (from the Red Sea to the Atlantic) with an extension of 9 million 200 thousand square kilometres or 3 million 600 thousand square miles . It means that all the Chinese territory (or even the USA’s territory) could be on it. It does not mean that the entire north of Africa is taken by the Sahara dessert: There are some territories with much fertility such as the Mediterranean coast, the Atlas Mountains, the Nile Valley.

Explanation:

The area of the Middle East which is marked green in the map is the Sahara Desert region. Though the area is surrounded by major water bodies, it has little or no groundwater for being a desert region.

What is Sahara Desert?

The Sahara desert is the world's third biggest desert, stretching from the Red Sea to the Atlantic Ocean and covering 9,200,000 square kilometres. It is the world's biggest hot desert and the third-largest desert overall, only smaller than the deserts of Antarctica and the northern Arctic.

The Nubian Sandstone Aquifer System (NSAS) is the largest documented fossil water aquifer system on the planet. It is situated underground in the Sahara desert's eastern end.

It does not imply that the entire north of Africa is taken by the Sahara dessert. Some fertile areas include the Mediterranean shoreline, the Atlas Mountains, and the Nile Valley.

Therefore, green on the map represents Sahara Desert.
