World & Physical Geography MCQs

Notes:
Geography is studied majorly by using two approaches
1. Systematic approach
2. Regional approach
Systematic geography approach was introduced by German Geographer Alexander Von Humboldt where as regional geography approach was introduced by another German geographer Karl Ritter .

Notes:
Kepler proposed Laws of planetary motion. These three laws describes the behavior of planets in the heliocentric model;
The three laws of Kepler can be stated as follows:
1. Law of orbits: All planets move in elliptical orbits with the Sun situated at one of the foci of the ellipse
2. Law of areas: The line that joins any planet to the sun sweeps equal areas in equal intervals of time.
3. Law of periods: The Square of the time period of revolution of a planet is proportional to the cube of the semi-major axis of the ellipse traced out by the planet. The law of areas can be understood as a consequence of conservation of angular momentum which is valid for any central force.

Notes:
Sedimentary rocks are types of rock that are formed by the accumulation or deposition of small particles and subsequent cementation of mineral or organic particles on the floor of oceans or other bodies of water at the Earth’s surface. Gypsum, Chalk & Limestone are the examples of sedimentary rocks.

Notes:
Eskimos live in the tundra climate. The tundra is part of the polar region, which is characterized by a frigid climate. The polar region includes the Arctic and the Antarctic. Eskimos are indigenous people who have traditionally lived in the northern circumpolar region. This region includes eastern Siberia, Alaska, Canada, and Greenland. Eskimos live in igloos during the winter and portable huts in the summer. The word “igloo” is the Eskimo word for “house”. Eskimos have developed unique skills and adaptations to survive in the extreme cold climates.

Notes:
Marble is a metamorphic rock composed of recrystallized carbonate minerals, most commonly calcite or dolomite. Marble is typically not foliated, although there are exceptions.

Notes:
Sunlight travels at the speed of light. Photons emitted from the surface of the Sun need to travel across the vacuum of space to reach our eyes. The short answer is that it takes sunlight an average of 8 minutes and 20 seconds to travel from the Sun to the Earth.

Notes:
The Archipelago Sea is a part of the Baltic Sea and it is the second largest archipelago in the world comprising around 40,000 islands, islets and reefs. It is located between The Gulf of Bothnia, the Gulf of Finland and the Sea of Aland.

Notes:
The Archipelago Sea is a part of the Baltic Sea, located within the boundaries of Finnish territorial water. It is of roughly triangular shape and the tips of the triangles are Finnish cities.

Notes:
The Gulf of Guinea is the northeastern most part of the tropical Atlantic Ocean. In this Gulf, there happens the intersection of the Equator and the Prime Meridian (zero degree latitude and longitude).

Notes:
Bahrain is the smallest gulf country in the world. It is a sovereign state in the Persian Gulf. It comprise 33 natural islands of which only three are inhabited. It also consists of 51 artificial islands.
