Physical Geography Quiz 3

Tundra ecosystems are treeless regions found in the Arctic and on the tops of mountains, where the climate is cold and windy (extreme), and rainfall is scant. Tundra lands are covered with snow for much of the year, but summer brings bursts of wild-flowers. Resident animals have to change what they are hunting and eating as the seasons change (nomadic hoarders).

Iron and Steel, Aluminium and Cement industries maximise savings on transport costs by being located near the sources of materials.

A falling air pressure generally means there is an approaching storm that will arrive within the next 12 to 24 hours.

Groundwater recharge depends on several factors such as infiltration capacity, stochastic characteristics of rainfall, and climate factors. The spatial and temporal distribution of the rainfall mainly controls the natural groundwater recharge.

Colourado, a western USA state, has a diverse landscape of arid desert, river canyons and snow-covered Rocky Mountains, which are partly protected by Rocky Mountain National Park. The Grand Canyon is a steep-sided canyon carved by the Colourado River.

The sphere of living matter together with water, air and soil on the surface of the earth is known as Biosphere. The biosphere, also known as the ecosphere, is the worldwide sum of all ecosystems.

Anthracite is the highest rank of coal. It contains a high percentage of fixed carbon and a low percentage of volatile matter. It is the most metamorphosed type of coal (but still represents low-grade metamorphism), in which the carbon content is between 86% and 98%.

Global warming is the long-term heating of Earth's climate system observed since the pre-industrial period (between 1850 and 1900) due to human activities, primarily fossil fuel burning, which increases heat-trapping greenhouse gas levels in Earth's atmosphere.

Humidity is inversely proportional to temperature. If temperature increases it will lead to a decrease in relative humidity, thus the air will become drier whereas when temperature decreases, the air will become wet means the relative humidity will increase.

Epicentre, point on the surface of the Earth that is directly above the underground point (called the focus) where fault rupture commences, producing an earthquake.
