World & Physical Geography MCQs

Notes:
The Odaesan National Park is situated in Gangwon city of South Korea. It was designated as national park in the year 1975.

Notes:
Earthquake is a sudden and violent movement, or fracture, within the earth followed by the series of shocks resulting from this fracture. Earthquake is more likely to be of Tectonic origin and probably because of existence of a Fault.

Notes:
One of today’s prevalent water issues is the rise in sea level. It is mainly caused by two phenomena: global warming and ozone depletion. Polar ice caps in Antarctica and other places are melting fast. This has led to increase in sea level over the years.

Notes:
Lateral or sideways erosion widens the river valley; while, Vertical or downward erosion deepens the river valley. Due to continued lateral erosion, the river valley increasingly becomes broader and shallower. The valley slopes are also eroded by weathering and mass wasting and by the development of tributary valleys.

Notes:
Hachures are short disconnected lines drawn on the map to depict the slope of the ground surface. They are drawn in rows; each row being disconnected from the other. They are short and closely spaced for steep slopes and relatively long and widely spaced for gentler slopes. Hachures are not drawn for leveled areas, such as flat valley or a plateau top.

Notes:
A ford is a shallow place with good footing where a river or stream may be crossed by wading or inside a vehicle. A ford is mostly a natural phenomenon, in contrast to a low water crossing, which is an artificial bridge that allows crossing a river or stream when water is low.

Notes:
Winter solstice is an astronomical phenomenon marking the shortest day and the longest night of the year. In the Northern Hemisphere this is the 21st December solstice and in the Southern Hemisphere this is the 21st June solstice. Solstices are opposite on either side of the equator, so the winter solstice in the northern hemisphere is the summer solstice in the southern hemisphere and vice versa.

Notes:
The stratosphere defines a layer in which temperatures rises with increasing altitude. At the top of the stratosphere the thin air may attain temperatures close to 0oC. This rise in temperature is caused by the absorption of ultraviolet (UV) radiation from the Sun by the ozone layer. Such a temperature profile creates very stable atmospheric conditions. Consequently, the stratosphere is almost completely free of clouds or other forms of weather.

Notes:
Estuaries and their surrounding wetlands are bodies of water usually found where rivers meet the sea. Estuaries are home to unique plant and animal communities that have adapted to brackish water—a mixture of fresh water draining from the land and salty seawater.

Notes:
Pygmies are nomadic hunter-gatherers who live in the equatorial rainforests of central Africa as well as parts of southeast Asia. They are nomadic, and obtain their food through a mix of foraging, hunting, fishing, and trading with inhabitants of neighboring villages. Their cultural identity is very closely tied to the rainforest, as are their spiritual and religious views.
