World & Physical Geography MCQs

Notes:
Einstein proposed theory of special relatively in the year 1905. According to this theory
E=mc²
Where
C= Speed of light
M= relative mass of a body
E= Kinetic energy
It means that the amount of energy in a piece of matter is equal to the mass of that piece of matter multiplied by the speed of light squared.

Notes:
There is a large gap in between the orbits of Mars and Jupiter. This gap is occupied by a large number of small objects that revolve around the Sun. These are called asteroids.

Notes:
1 hour is equal to 15 degress. 360 degrees is equal to 24 hours and when we divide 360 by 24 we get each hour equal to 15 degree.

Notes:
The Java Trench—contrary to the other options—is not situated within the Pacific Ocean; it actually lies within the Indian Ocean. Trenches are long, narrow, steep-sided depressions in the ocean floor, most of which culminate in the Pacific Ocean. However, the Java Trench, which is considered the deepest point in the Indian Ocean, makes for a notable exception to this majority.

Notes:
The nebular hypothesis is model which explain the formation and evolution of the Solar System. It suggests that the Solar System formed from gas and dust orbiting the Sun.

Notes:
One loses a day when he/she crosses 180 degrees longitude from east to west and gains a day when crosses 180 degrees from west to east.

Notes:
In geography, a mesa is a flat-topped mountain with steep sides, while a butte is a flat-topped hill with steep sides. The choice between mesa and butte depends on the shape and size of the landform.
A mesa is an isolated, broad, flat-topped mountain with at least one steep side. Mesas are smaller in area than a plateau. Mesas are abundant in the southwestern states of Colorado, New Mexico, Utah, and Arizona.
A butte is a small isolated flat-topped hill with steep sides. Buttes are smaller in area than a mesa. Buttes are typically isolated landmarks that appear steep-sided and flat-topped, though often only from certain angles. Buttes were created through the process of erosion, the gradual wearing away of earth by water, wind, and ice.
The word butte comes from the French word butte, meaning knoll. The word mesa comes from the Spanish word for “table”.

Notes:
Diamond is a solid form of the element carbon with its atoms arranged in a crystal structure called diamond cubic. Emerald is a gemstone and a variety of the mineral beryl (Be₃Al₂(SiO₃)₆) colored green by trace amounts of chromium and sometimes vanadium.

Notes:
The Seto Inland Sea, also known as Setouchi serves as a waterway and it connects the Pacific Ocean and the Sea of Japan.

Notes:
The New Caledonian Barrier Reef is the longest continuous barrier reef in the world and the third largest reef as well. It is located in the New Caledonia in the South Pacific.
