Geography Mixed Quiz: Set 114

Lithification is the name for turning loose sediment into solid rock. Fragments produced by weathering and erosion are carried by rivers, wind, glaciers or waves and laid down in layers.

Where water is abundant and flooding is a danger, people avoid the low wet land and build on the levee, the terrace or any patch of higher dry ground, and such a site is called a dry point.

The Richter scale measures the magnitude of an earthquake, which reflects the energy released at its source, not its intensity.

The Strait of Hormuz lies between Iran on the north and Oman and the United Arab Emirates on the south, and is the only sea passage from the Persian Gulf to the Gulf of Oman and so to the Arabian Sea; a very large share of the crude oil traded…

The Agulhas current flows in the Indian Ocean, down the south-east coast of Africa, so it is not a Pacific current.

The Pampas spread over the plains of Argentina and extend into Uruguay, and they are the home of wheat and alfalfa farming, of large cattle ranches called estancias and of the herdsmen known as gauchos; the grassland owes its growth to moderate rainfall and the cool season of the mid…

Pressure of water breaks rock mechanically without changing its minerals, so it is a physical process. Weathering is the breaking down of rocks where they lie.

The Ganga flows from west to east across the northern plains, so the cities follow the order in which the river reaches them.

Relative humidity compares the moisture in the air with what the air could hold, and that capacity rises with temperature.

A cyclone is a low pressure system, so air flows inwards towards the centre, and the Coriolis force deflects moving air to the left in the Southern Hemisphere, which turns that inflow into a clockwise spiral.

The Amsterdam-St. Paul Plateau is a raised area of the ocean floor in the southern Indian Ocean, named after the French islands of Amsterdam and Saint-Paul that rise from it.

The Greek bathos means depth, so isobaths are the depth contours of a bathymetric chart; the 200 metre isobath is conventionally taken as the outer edge of the continental shelf.

The Irrigation Commission of 1972 treated an area as drought-prone when less than 30 per cent of its gross cropped area was irrigated, so an area with 30 per cent or more is left out.

It lies in a rift valley in southern Siberia, reaches a depth of about 1,642 metres and holds more fresh water by volume than any other lake, roughly a fifth of the unfrozen surface fresh water of the earth.

The Panama Canal cuts across the narrow Isthmus of Panama in Central America and joins the Caribbean Sea, an arm of the Atlantic, with the Gulf of Panama on the Pacific.

The Zemu glacier lies in North Sikkim at the eastern base of Kangchenjunga, the highest peak in India, and its meltwater reaches the Teesta river.

Detroit stands on the Detroit River, which links Lake St. Clair to Lake Erie, and is far from Lake Superior.

Valley glaciers scour away soil, regolith and loose sediment and deepen their valleys into U-shaped glacial troughs, but a fiord forms only when the trough floor lies below sea level, not above it.

Dryland farming is practised where annual rainfall is below about 75 cm. Indian agriculture is grouped by the source of moisture into irrigated and rainfed farming, and rainfed farming is further divided into dryland and wetland farming.

Both statements describe standard facts about how air temperature is measured and how it changes with height.
