General Geographical Features Test - 2

Cloudy nights are less likely to experience dew formation at the Earth's surface because radiation cooling is reduced. Wind will also reduce the chance of dew formation as it reduces the humidity (and therefore the dew point) of the air in contact with the ground.

Hygrometer, instrument used in meteorological science to measure the humidity, or amount of water vapour in the air. Several major types of hygrometers are used to measure humidity.

The five main types of precipitation are rain, snow, hail, sleet, and freezing rain. So, Snow, Dew and Hail are the forms of precipitation.

Meteorologically, a drop in barometric reading means atmospheric pressure is falling.A barometer that is falling indicates that a low pressure system is moving in, and you can expect poorer weather i.e a storm . A storm is any disturbed state of an environment It may be marked by significant disruptions to normal conditions such as strong wind, tornadoes, hail, thunder and lightning , heavy precipitation etc.

Water vapor normally begins to condense on condensation nuclei such as dust, ice, and salt in order to form clouds. Fog, like its elevated cousin stratus, is a stable cloud deck which tends to form when a cool, stable air mass is trapped underneath a warm air mass. Fog normally occurs at a relative humidity near 100%.

Hail is a type of precipitation, or water in the atmosphere. Hail is formed when drops of water freeze together in the cold upper regions of thunderstorm clouds or Cumulonimbus clouds. Cumulonimbus is a dense, towering vertical cloud, forming from water vapor carried by powerful upward air currents.

Fog is a visible aerosol consisting of tiny water droplets or ice crystals suspended in the air at or near the Earth's surface. Fog can be considered a type of low-lying cloud, usually resembling stratus, and is heavily influenced by nearby bodies of water, topography, and wind conditions.

Dew points indicate the amount moisture in the air. The higher the dew points, the higher the moisture content of the air at a given temperature. Dew point temperature is defined as the temperature to which the air would have to cool (at constant pressure and constant water vapor content) in order to reach saturation.

In meteorology, leeward and windward are technical names for the directional sides of a mountain. The windward side is that side which faces the prevailing wind (upwind), whereas the leeward, or "lee" side, is the side sheltered from the wind by the mountain's very elevation (downwind).
Orographic rainfall leads to the formation of the windward and the leeward side. It is a rain that is produced from the lifting of moist air over a mountain.

Rocks are composed of grains of minerals, which are homogeneous solids formed from a chemical compound arranged in an orderly manner.Rocks are formed when magma cools in the Earth's crust, or lava cools on the ground surface or the seabed.
