World & Physical Geography MCQs

Notes:
Jupiter, Saturn, Uranus and Neptune are called as the outer planets or Jovian planets or Gas Giant. Most of them are much larger than the terrestrial planets and have thick atmosphere, mostly of helium and hydrogen.

Notes:
Sukkur Barrage or Lloyd Barrage is a barrage on the River Indus near the city of Sukkur in the Sindh province of Pakistan. It was built during the British Raj from 1923 to 1932.

Notes:
China is the world’s leading producer of synthetic industrial diamonds. Industrial diamonds can be used in cutting, drilling, grinding, and polishing.

Notes:
The term “cosmic rays” was coined by the Austrian physicist Victor Francis Hess in 1912. Hess was awarded the Nobel Prize in Physics in 1936 for his discovery of cosmic rays.

Cosmic rays are high-energy particles that travel through space and reach the Earth’s atmosphere. They are believed to be made up of protons, electrons, and atomic nuclei, and they can have energies that are millions or billions of times greater than those of particles produced by particle accelerators on Earth.

Hess discovered cosmic rays while conducting experiments in which he flew high-altitude balloon flights to measure the radiation levels at different altitudes. He found that the radiation levels increased with altitude, leading him to conclude that the radiation was coming from outer space and not from the Earth’s surface. He named these high-energy particles “cosmic rays” because they seemed to be coming from the cosmos.

Notes:
The Float at Marina Bay in Singapore was built in 2007. It is the largest floating stage in the world. It is also as football stadium.

Notes:
The K2 Peak, the second-highest mountain in the world at 8,611 meters (28,251 feet), is located in the Karakoram range. This range spans the borders of Pakistan, India, and China and is known for its challenging climbing conditions. K2 is often referred to as “Savage Mountain” due to its high fatality rate among climbers. The Karakoram range also includes other notable peaks, such as Gasherbrum I and Broad Peak.

Notes:
The Cocos Ridge, also called the Galapagos hotspot, is an underwater volcanic ridge in the East Pacific Ocean. It is formed by the Galapagos hotspot, which created the Galapagos Islands and major ridges like Carnegie, Cocos, and Malpelo.

Notes:
Cirrostratus is the only clouds which is responsible for the formation of haloes. A halo is an optical phenomena produced by light interacting with ice crystals suspended in the atmosphere. It leads to formation of colored or white rings or arcs and spots in the sky.

Notes:
Siderite is a mineral composed of iron(II) carbonate (FeCO3). It takes its name from the Greek word ‘sideros’, “iron”. It is a valuable iron mineral, since it is 48% iron and contains no sulfur or phosphorus.

Notes:
Conditions favourable for the formation of the Deltas:
• Active vertical and lateral erosion in the upper course of the river to provide extensive sediments to be eventually deposited as deltas.
• The sea adjoining the delta should be shallow or else the load will disappear in the deep waters.
Conditions not favourable for Delta formation:
• Tides
• Strong and regular currents
