A geostationary satellite is an earth-orbiting satellite, placed at an altitude of approximately 35,800 km directly over the equator, that revolves in the same direction the earth rotates (west to east).

The International Date Line, established in 1884, passes through the mid-Pacific Ocean and roughly follows a 180 degrees longitude north-south line on the Earth. It is located halfway round the world from the prime meridian—the zero degrees longitude established in Greenwich, England, in 1852.

Four major types of air masses that influence the weather in North America are: Maritime Tropical (mT), Maritime Polar (mP), Continental Tropical (cT) and Continental Polar (cP). The climate of North America is influenced during winter by the Continental Polar air mass. The most common example of continental polar air entering the U.S. comes in winter, when the jet stream dips southward, carrying cold, dry cP air, sometimes as far south as Florida. When it moves across the Great Lakes region, cP air can trigger lake effect snow.

Westerlies are called anti-trade wind. The westerlies are prevailing winds from the west toward the east in the middle latitudes between 30 and 60 degrees latitude. They originate from the high-pressure areas in the horse latitudes and trend towards the poles and steer extratropical cyclones in this general manner.

Mica is common in igneous and metamorphic rock and is occasionally found as small flakes in sedimentary rock. It is abundant in many rocks, e.g., shale, slate, phyllite, schist, gneiss, and granite.

Thus most of the tropical deserts like The Sahara Desert, the Kalahari Desert, West Australian desert, etc. are located on the western margin of the continent. Moreover, these deserts also lie on the leeward side of the mountains and hence the region is also hot and dry.

In frost covered plants, ice crystals form inside plant cells. These crystals cause expansion of cells. Cells can expand up to a certain limit, after which they got ruptured and plants ultimately are killed due to mechanical damage.

Loktak Lake is the largest freshwater lake in India as well as the largest lake in North East India. It is famous for the phumdis floating over it. The lake is located at Moirang in Manipur.

The Yarlung Tsangpo, also called Yarlung Zangbo or Yalu Zangbu is the upper stream of the Brahmaputra River located in the Tibet Autonomous Region, China.
