World & Physical Geography MCQs

Notes:
Consumption of practically the entire produce in the area of production is the chief characteristic of subsistence farming. It is the dominant type of agricultural activity in the densely settled regions of Asia. The chief crops under the subsistence agriculture are the food grains.

Notes:
Mining is the activity of obtaining minerals from the surface of the earth or from the rocks from below the surface. 
Minerals obtained from under the ground by means of making large dug out hollows is called open-cast mining.

Notes:
The transport, communications and services sector plays an important role in the economic development today in spite of the fact that this sector does not produce any goods. Means of transport and communication are today called lifelines of an economy.

Notes:
Strait of Bonifacio is a navigable waterway located in the Mediterranean Sea which separates Corsica Island of France and Sardinia Island of Italy. Thereby, France and Italy form the basin countries of the Strait of Bonifacio. This strait divides the Tyrrhenian Sea from the western Mediterranean Sea. This strait is notorious among sailors for its weather, currents, shoals, and other obstacles. Strait of Bonifacio houses the Lavezzi Archipelago, administrated by France, which is a collection of small granite islands and reefs. France-Italy Maritime Boundary Agreement was signed in 1986 between France and Italy to delimit the maritime boundary between the two countries in the Strait of Bonifacio.

Notes:
The Saronic Islands or Argo-Saronic Islands is an archipelago in Greece, named after the Saronic Gulf in which they are located, just off the Greek mainland. The islands of Hydra and Dokos, which lie off the northeast tip of the Peloponnese (technically between the Saronic Gulf and the Argolic Gulf), are sometimes included as part of the Saronic Islands.

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:
The Carrauntoohil is the highest peak of Ireland which is about 1041 meters high above the mean sea level. It is located in the Iveragh peninsula in Reeks district.

Notes:
Mercury is the innermost planet (nearest to the Sun) in the Solar System. It is also the smallest, and its orbit is the most eccentric (that is, the least perfectly circular) of the eight planets. It orbits the Sun once in about 88 Earth days, completing three rotations about its axis for every two orbits.

Notes:
Igneous rocks are formed through the cooling and solidification of magma (or lava). As hot, molten rock rises to the surface, it undergoes changes in temperature and pressure that cause it to cool, solidify, and crystallize. There are over 700 known types of igneous rock, the majority of which are formed beneath the surface of the Earth’s crust. However, some are also formed on the surface as a result of volcanic activity.

Notes:
A land cyclone is a rare weather system with a low-pressure center that forms over land, occurring only 14 times since 1891. A mesocyclone is an air vortex within a convective storm, with a diameter of 3.2 to 9.7 km. A subtropical cyclone combines features of tropical and extratropical cyclones and forms at lower sea surface temperatures than tropical cyclones. Wave cyclones, or extratropical cyclones, are low-pressure areas that develop in middle and high latitudes, primarily between 30° and 60° latitude.
