World & Physical Geography MCQs

Notes:
Second statement is incorrect because Venus is the second brightest object in our night sky after Moon.

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:
Intrusive igneous rocks are formed from magma that cools and solidifies within the crust of a planet, surrounded by pre-existing rock (called country rock); the magma cools slowly and, as a result, these rocks are coarse-grained. Granite is the example of Intrusive Igneous rock.

Notes:
The nations with the largest mangrove areas include Indonesia (with 21% of global mangroves), Brazil (9%), Australia (7%), Mexico (5%), and Nigeria (5%).

Notes:
The distance between two consecutive longitudes(91 degree E and 92 degree E) at the Poles is 0 km. The distance between two consecutive meridians of longitude is equal to 111 km only at equator. The distance between two consecutive parallels of latitude is equal to about 111 km.

Notes:
Paleoclimatology is the study of ancient climates, prior to the widespread availability of instrumental records. Scientists can use those environmental recorders to estimate past conditions, extending our understanding of climate back hundreds to millions of years.

Notes:
The Gulf of Ob is the world’s longest estuary. It’s located in the Arctic Ocean at the mouth of the Ob River in northern Russia. The Gulf of Ob is roughly 1,000 km long and 50–80 km wide. It’s also the migration ground for Beluga whales.  The Ob River is one of three great Siberian rivers that flow into the Arctic Ocean. The other two are the Yenisei River and the Lena River. The Ob River forms 25 km (16 mi) southwest of Biysk in Altai Krai at the confluence of the Biya and Katun rivers. The main city on its banks is Novosibirsk, the largest city in Siberia, and the third-largest city in Russia.

Notes:
Mount Kilimanjaro is located in [C] Tanzania. It is the highest mountain in Africa and is known for its distinctive volcanic cones and snow-capped peaks.

Notes:
The Himalayan Rivers are perennial rivers because they originate in snow covered Himalayan Mountains. They start from the glaciers that seem to melt all over the year. During summers, the snow melts and the rivers get continuous supply of water. On the contrary, the peninsular rivers depend mostly on rainfall for its supply of water and thus become dry during the summer season.
