World & Physical Geography MCQs

Notes:
The longest river of Ireland is River Shannon which is about 360 Km long. Shannon river separates midlands of Ireland from west of the island.

Notes:
The Razna National Park is situated in the Latgale region of Latvia. It was designated in the year 2007 and it covers an area of about 596 sq. km.

Notes:
The solar mass is used to indicate the masses of other stars, as well as clusters, nebulae and galaxies. It is equal to the mass of the Sun, about two nonillion (two quintillion in the long scale) kilograms. It is equal to approximately 1.99 × 1030 kilograms.

Notes:
A natural celestial object is visible in the sky such as a star, planet, natural satellite, asteroid, comet, the Moon or the Sun. A constellation is a group of stars that appears to form a pattern or picture. For example: Orion the Great Hunter, Leo the Lion, or Taurus the Bull. Asteroids are small, rocky objects that orbit the sun. A meteoroid is a small rocky or metallic body in outer space.

Notes:
In physical geography, tundra is a biome where the tree growth is hindered by low temperatures and short growing seasons. There are three types of tundra: Arctic tundra, alpine tundra, and Antarctic tundra where the subsoil is permafrost, or permanently frozen soil. Rainfall and snowfall are generally slight due to the low vapor pressure of water in the chilly atmosphere, but as a rule potential evapotranspiration is extremely low, allowing soggy terrain of swamps and bogs even in places that get precipitation typical of deserts of lower and middle latitudes.

Notes:
During the Rainy Season in India (Mid-June to the end of September), the intense heat that prevails in the Indian subcontinent causes a low pressure region over the Northern Plains in the Northwestern parts of the country. It is intense enough to attract the moisture- bearing winds from the Indian Ocean. Thus, the south-east trade winds from the Southern Hemisphere are attracted towards India. On crossing the equator, they are deflected to their right and blow over the Indian subcontinent as the south-west monsoon winds.

Notes:
The Ocean Currents consists of horizontal and vertical components of the circulation system of ocean waters that is produced by gravity, wind friction, and water density variation in different parts of the ocean. Warm ocean currents originate near the equator and move towards the poles or higher latitudes while cold currents originate near the poles or higher latitudes and move towards the tropics or lower latitude.

• Gulf Stream: Warm Current
• Agulhas Current: Warm Current
• Labrador Current: Cold Current
• Alaskan Current: Warm Current

Notes:
Soil salinity is the salt content in the soil; the process of increasing the salt content is known as salinization. Excess irrigation leads to increase in soli salinity since water is absorbed by plants and salts are left behind in the soil and eventually begin to accumulate. Salination from irrigation water is also greatly increased by poor drainage and use of saline water for irrigating agricultural crops.

Notes:
It is due to the North Atlantic Drift which is a warm water ocean current, an extension of the Gulf Stream. This current keep the ports along the coasts warm enough to stay open year around.

Notes:
Pakistan is known as country of Canals due to its extensive network of canals from Indus and its tributaries. Most of Pakistan’s canals are in Punjab province that are result of India’s partition which saw most of the canals going to the former. During India’s partition, Punjab was divided into West Punjab which came to be part of Pakistan and East Punjab which remained with India. East Punjab in India was relatively underdeveloped in irrigation works, while West Punjab in Pakistan included most of the canal systems of the pre-partition Indus basin.
