World & Physical Geography MCQs

Notes:
The (Northern) Sporades are an archipelago along the east coast of Greece, northeast of the island of Euboea, in the Aegean Sea. They consist of 24 islands, four of which are permanently inhabited: Alonnisos, Skiathos, Skopelos and Skyros. They may also be referred to as the Thessalian Sporades.

Notes:
Grenada is a sovereign country in the West Indies in the Caribbean Sea at the southern end of the Grenadines island chain. Grenada consists of the island of Grenada itself, two smaller islands, Carriacou and Petite Martinique, and several small islands which lie to the north of the main island and are a part of the Grenadines. It is located northwest of Trinidad and Tobago, northeast of Venezuela and southwest of Saint Vincent and the Grenadines.

Notes:
The Atlantic Ocean forms the coastline of the “Bissagos Islands”. The Bissagos Islands are a group of about 88 islands and islets located in the Atlantic Ocean off the coast of the African nation of Guinea-Bissau. The archipelago was formed from the ancient delta of the Rio Geba and the Rio Grande. There is a high diversity of ecosystems: mangroves with intertidal zones, palm forests, dry and semi-dry forests, secondary and degraded forests, coastal savanna, sandbanks and aquatic zones. The archipelago was declared in 1996 a UNESCO Biosphere Reserve—Bolama Bissagos Biosphere Reserve, known for animals including marine turtles, hippopotamus and the southern islands are today a nature reserve.

Notes:
The Acarai Mountains are a wet, forested highland region of low mountains located in the southern part of Guyana. This range lies along the common border between Guyana and Brazil. The Acarai Mountains is one of four mountain ranges in Guyana, the others being the Imataka, Kanuku and Pakaraima mountains.

Notes:
The Republic of the Niger is a landlocked country situated in west Africa. It shares the largest border with Nigeria which is about 1497 km long.

Notes:
Stars twinkle because they are point light sources. Passing through the atmosphere, the small beam of light constantly shifts by bouncing off particles in the air. The much closer planets appear instead as tiny disks in the sky. Their apparent sizes are usually larger than the pockets of air that would distort their light, so the effects of scintillation are negligible. Being closer, planets appear as discs, with the shifting of light from one side cancelling out the other.

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:
The troposphere is the lowest portion of Earth’s atmosphere. It contains approximately 80% of the atmosphere’s mass and 99% of its water vapor and aerosols. The average depth of the troposphere is approximately 17 km in the middle latitudes. It is deeper in the tropics, up to 20 km, and shallower near the Polar Regions, at 7 km in summer, and indistinct in winter. Most of the phenomena we associate with day-to-day weather occur in the troposphere..

Notes:
A desert is a barren area of land where little precipitation occurs and consequently living conditions are hostile for plant and animal life. Lack of or insufficient precipitation is the main reason behind the lack of vegetation.

Notes:
The mid-latitude grasslands are called the world’s bread baskets regions of grain and l ivestock production. They are found in the middle latitudes of South America, North America, Africa and Asia.
