World & Physical Geography MCQs

Notes:
Venus was the first planet to have its motions plotted across the sky, as early as the second millennium BC.

Notes:
One Nautical Mile is the unit of length corresponding approximately to one minute of arc of latitude along any meridian. By international agreement it is exactly 1,852 metres (approximately 6,076 feet).

Notes:
Great Herring Pond is a 376-acre warm water pond mostly located in Plymouth, Massachusetts, with the southern portion extending into Bourne. It is in Atlantic ocean.

Notes:
Mercator projection is the standard map projection for nautical purposes. It was created in 1569 by Gerardus Mercator for navigational purposes. The Mercator projection is widely used for navigation charts because any straight line on a Mercator projection map is a line of constant true bearing. This enables a navigator to plot a straight-line course.  The Mercator projection is uniquely suited to marine navigation because it maps trajectories of constant bearing (called rhumb lines or loxodromes) to straight lines. Courses and bearings are measured using a compass rose or protractor, and the corresponding directions are easily transferred from point to point.  The Mercator projection became popular because it shows relative sizes accurately and is useful for navigation.

Notes:
Tundra vegetation is composed of dwarf shrubs, sedges and grasses, mosses, and lichens. Scattered trees grow in some tundra regions.

Notes:
The four seasons happen because of the tilt of the Earth’s axis. At different times of the year, the sun’s rays hit different parts of the globe more directly. The angle of the Earth’s axis tilts the Northern Hemisphere towards the sun during the summer.

Notes:
Andros island in the Bahamas has the largest collection of the blue holes. Andros is the largest island in the Bahamas and it more than 200 Blue Holes. Blue Holes are usually sink holes or underwater caves in shape of a circle.

Notes:
Juhu Beach is a west coat beach in India. It is the longest beach in Mumbai. It stretches for nearly 6 km along the shores of the Arabian Sea. The beach features short, rocky formations unlike other sandy beaches.

Notes:
The colour of the star reflects its temperature. Since wavelength of blue is minimum, its temperature is maximum ( Wein’s displacement law).

Notes:
Light takes 8 minutes 19 seconds to reach from the surface of the sun to the surface of the Earth.
