Physical Geography Quiz 3

A geosynchronous orbit is located at 35,786 km above Earth's equator. This position is a valuable spot for monitoring weather, communications and surveillance. Geosynchronous orbit is an Earth-centered orbit with an orbital period that matches Earth's rotation on its axis, 23 hours, 56 minutes, and 4 seconds.

About 2.1% of all of Earth's water is frozen in glaciers. About 70% of Earth's freshwater is stored in glaciers.

A nebula is an interstellar cloud of dust, hydrogen, helium and other ionized gases. It does not belong to the solar system.

An equinox is one of the two times of the year (21 March and 22 September) when the amount of daylight and night time hours are just about equal duration.

Pluto is farthest from the Earth. Our Solar System has eight planets which orbit the sun. In order of distance from the sun they are; Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune. Pluto, which until recently was considered to be the farthest planet, is now classified as a dwarf planet.

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.

Isobars are lines on a weather map that join places that have the same air pressure at a particular time.

The air above the land warms up and rises and the cool air over the sea moves in to take its place, resulting in the sea breeze in the daytime. At night, as the sea maintains its temperature better and is warmer than the land, the roles of land and sea reverse and convection of air results in the land breeze.

Venus is the brightest planet in our Solar System. It can be seen with the unaided eye from Earth.

Isoneph is a line on a map connecting points that have the same average percentage of cloudiness.
