World & Physical Geography MCQs

Notes:
Cartography is the study and practice of making maps.
Study of mountains- Orology
Study of land forms -Geomorphology
Study of oceans- Oceanography

Notes:
The Andromeda is a Galaxy. It is also known as Messier 31, M31, or NGC 224 and originally the Andromeda Nebula. It is approximately 2.5 million light-years from Earth and the nearest major galaxy to the Milky Way.

Notes:
While going towards the centre of the earth, the weight of a body shall decrease. This is because the distance from the centre of the earth reduces.

Notes:
Andes is the world’s longest above-water mountain range, spanning over 4,300 miles. It’s located on the South American continent and crosses the borders of seven countries:
Venezuela, Bolivia, Chile, Colombia, Ecuador, Peru, Argentina.
The Andes stretches from Tierra del Fuego in the south to the continent’s northernmost coast on the Caribbean Sea. It’s also known for its volcanoes.
The longest mountain range on Earth is the mid-sea edge, which spans over 40,389 miles. Around 90% of the mid-sea edge framework is under the sea. The mid-ocean ridge system is part of every ocean in the world and marks the boundaries of the oceanic plates. It rises to 6,600 feet above the deepest part of the ocean basin.

Notes:
An Isochrone is defined as “a line drawn on a map connecting points at which something occurs or arrives at the same time".

Notes:
The difference between highest and lowest temperature in a day at given point is known as diurnal or daily range of temperature. The highest diurnal range of temperature is recorded in the hot deserts of the world. The daily range of temperature near poles is almost zero. The daily range of temperature over oceans is also very low.

Notes:
The three main types of rock are sedimentary, metamorphic, and igneous. Every rock has characteristics that reflect its process of formation; these are used to determine whether the rock is igneous, sedimentary or metamorphic. For example, a rock with rounded grains cemented together is sedimentary, while one with a strong banding and orientation of minerals is metamorphic.

Notes:
Most eskers are argued to have formed within ice-walled tunnels by streams which flowed within and under glaciers. They tended to form around the time of the glacial maximum when the glacier was slow and sluggish. After the retaining ice walls melted away, stream deposits remained as long winding ridges.
Drumlin, oval or elongated hill believed to have been formed by the streamlined movement of glacial ice sheets across rock debris, or till. Drumlins are commonly found in clusters numbering in the thousands. Often arranged in belts, they disrupt drainage so that small lakes and swamps may form between them.

Notes:
The C layer lies immediately above the R layer (bottom most layer). It consists of broken rock fragments and it is devoid of any organic content. C layer is also called as Saprolite.

Notes:
The Thirty Thousands Islands is the world’s largest freshwater archipelago and it is located along the east side of Georgian Bay which is the part of the Great Lakes, in Ontario, Canada.
