World & Physical Geography MCQs

Notes:
The Rhodopes are a mountain range in Southeastern Europe, with over 83% of its area in southern Bulgaria and the remainder in Greece. Golyam Perelik is its highest peak at 2,191 meters. The mountain range gives its name to the terrestrial ecoregion Rhodope montane mixed forests that belongs in the temperate broadleaf and mixed forests biome and the Palearctic realm. The region is particularly notable for its karst areas with their deep river gorges, large caves and specific sculptured forms, such as the Trigrad Gorge.

Notes:
Iceland houses the “Gullfoss Waterfalls”. Gullfoss is a waterfall located in the canyon of the Hvita river in southwest Iceland. Gullfoss is one of the most popular tourist attractions in Iceland. Together with Thingvellir and the geysers of Haukadalur, Gullfoss forms part of the Golden Circle, a popular day excursion for tourists in Iceland.

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:
Sideways form of erosion is called lateral erosion. In lateral erosion, the river erodes away at its banks and widens the river channel. Together, vertical and lateral erosion create the distinctive V-shaped valley that is found in rivers in their upper course. As the river gets closer to the sea, there is more lateral erosion than vertical erosion and the V flattens out into a much wider shape.

Notes:
Ursa Major, also known as Great Bear, is a constellation in the northern sky. In antiquity, it was one of the original 48 constellations listed by Ptolemy, and is now the third largest constellation of the 88 modern constellations. It is visible throughout the year from most of the northern hemisphere, and appears circumpolar above the mid-northern latitudes.

Notes:
The youthful stage of the river is when water flow is the quickest. Because of steep slope and steep channel gradient in this stage, rivers actively deepen their valleys through vertical erosion. The valley becomes deep and narrow characterized by steep valley side slopes of convex plan. Waterfalls, V-shaped valleys and interlocking spurs are features of this stage.

Notes:
A river delta is a landform created by deposition of sediment that is carried by a river as the flow leaves its mouth and enters slower-moving or stagnant water. This occurs where a river enters an ocean, sea, estuary, lake, reservoir, or (more rarely) another river that cannot carry away the supplied sediment.

Notes:
The rubber plant grows wild in the equatorial regions of the world which are marked by rainfall of around 250 cm evenly distributed without any marked dry season and with at least 100 rainy days per year; temperature range of about 20°C to 34°C with a monthly mean of 25°C to 28°C; and high atmospheric humidity of around 80%.The three largest producing countries, Thailand, Indonesia and Malaysia, together account for around 72% of all natural rubber production.

Notes:
The Mahaweli River is a 335 km long river, ranking as the longest river in Sri Lanka. It has a drainage basin of 10,448 km2 covering almost one-fifth of the total area of the island.

Notes:
Border countries on Caspian sea are Kazakhstan, Iran, Azerbaijan, Russia and Turkmenistan.
