World & Physical Geography MCQs

Notes:
Biogeography is the study of the interface between physical geography and human geography. Biogeography includes
a. Plant Geography
b. Animal Geography
c. Ecology
d. Environmental Geography

Notes:
The Milky Way is a barred spiral galaxy 100,000–120,000 light-years in diameter containing 200–400 billion stars

Notes:
Cuba is traditionally known as the “Sugar bowl of the world” as it used to be the worlds largest sugar producer. But now brazil has taken the top spot in sugar production.

Notes:
The Chukchi Sea is located in the Arctic Ocean, between Russia and the United States. It is also known as the Chuuk Sea or the Sea of Chukotsk.

Notes:
Tropical desert regions, such as the Sahara Desert, experience significant day-night temperature differences. During the day, temperatures in these areas can become extremely hot, often exceeding 100 degrees Fahrenheit (38 degrees Celsius), while nighttime temperatures can drop significantly, sometimes plummeting to near-freezing levels, particularly in desert areas with low humidity. This makes the day-night temperature difference in tropical deserts quite substantial.

Notes:
Radiation is the process by which most energy is transferred through space from the sun to the earth. Radiation is given off by all bodies including earth and human being. The hotter is the body, shorter are the waves. We can simply say that the radiation from Sun comes to earth in the form of smaller waves and earth being cooler body, gives off energy in the form of long-wave. These are then radiated back to the atmosphere. This Long-Wave Radiation from the earth’s surfaces heats the lower layers of the atmosphere. It is evident that the atmosphere is primarily heated from below by radiation from the heated Earth surface.

Notes:
A black hole is a region of spacetime exhibiting gravitational acceleration so strong that nothing—no particles or even electromagnetic radiation such as light—can escape from it. The theory of general relativity predicts that a sufficiently compact mass can deform spacetime to form a black hole.

Notes:
Gulf of Thailand is the part of the South China Sea. It is also known as the Gulf of Siam. It is a marginal water body in the western Pacific Ocean. It is surrounded by Cambodia and Vietnam in the northeast, and by Thailand in the rest part.

Notes:
Mefonna Glacier is located in the Svalbard Archipelago in the Arctic Ocean. The glacier is about seven km long and it drains both northwards and southwards.

Notes:
Astronomical Unit is the unit of length. It is the mean distance between the Sun and the Earth. One AU is equal to 150 million km.
