World & Physical Geography MCQs

Notes:
The correct answer is Western Disturbances. These are weather systems originating in the Mediterranean region that bring moisture-laden winds to the Indian subcontinent, particularly affecting northern India, including Bihar, Uttar Pradesh, and West Bengal. They typically occur during winter and early spring, contributing to rainfall and influencing the agricultural patterns in these regions. Eastern Disturbances are less common and do not importantly impact these areas.

Notes:
Planetary or permanent winds blow from high pressure belts to low pressure belts in the same direction throughout the year. They never change the direction. They blow over vast area of continents and oceans. They are easterly and westerlies and polar easterlies.

Notes:
Arete,Cirque, Groove, Moraines, Flood planes are the landforms associated with the erosion acitivity. It means weathering mainly.

Notes:
The Strait of Magellan located at the southern tip of South America. It is a 350-mile (570 km) channel. It connects the Atlantic Ocean and the Pacific Ocean.

Notes:
Heliopose is the theoretical boundary beyond which Solar Winds can not reach. The heliosphere is the vast, bubble-like region of space which surrounds and is created by the Sun.

Notes:
A rift valley is a long, narrow valley that forms where the Earth’s crust is being pulled apart and is typically associated with the process of continental rifting. Rift valleys are often found along the boundary between two tectonic plates, and they are typically steep-sided and bounded by faults. As the plates move apart, the ground between them sinks, forming a depression that eventually becomes a valley. This process can take millions of years, and over time, the rift valley can become filled with sediment and other materials, forming a lowland area.

Notes:
Stars seem to twinkle or change their brightness all the time. In fact, most stars shine with a steady light. The movement of air (sometimes called turbulence) in the Earth`s atmosphere causes the starlight to get slightly bent as it travels from the distant star through the atmosphere to us on the ground. Some of the light reaches us directly but some gets bent slightly. This gives the illusion of twinkling. Stars closer to the horizon appear to twinkle more than others. This is because the atmosphere is a lot denser near the horizon than between the Earth and a star higher in the sky.

Notes:
The Tephra is all the volcanic material such as Ash, Plumes, Volcanic Bombs, Volcanic Blocks, lapilli etc

Notes:
Gulfs with narrow fronts and wider rears would expect highest tides among all the four configurations. One example is Gulf of Mexico. The Gulf of Mexico has high tides because all the water must get in and out of the Gulf through the narrow Florida Straits.

Notes:
Over the western North Pacific and the South China Sea, tropical cyclones having maximum sustained winds reaching 118 km/h or more are known as ‘typhoons’.
