What are the factors affecting the movement of air

There are 5 major factors affecting global air circulation : – uneven heating of earth’s surface, seasonal changes in temperature and precipitation, rotating of earth on its axis, properties of air and water and long term variation in the amount of solar energy striking the earth.

What is the basic process that causes the movement of air

Answer. The movement of air through Earth’s or any planet’s atmosphere is called wind, and the main cause of Earth’s winds is uneven heating by the sun. This uneven heating causes changes of atmospheric pressure, and winds blow from regions with high pressure to those with low pressure.

What is wind What are the factors affecting movement of air

Sun is the ultimate force that drives winds. … Pressure differences force winds to flow from high pressure are to low pressure area. Pressure differences in turn are caused by unequal heating of the earth’s surface by solar radiation. The wind at the surface experiences friction.

How do you say up in the air

What is the word for air we breathe in

breathable. adjective. air that is breathable is clean enough or suitable for people to breathe.

What happens when two air masses meet

When two air masses meet together, the boundary between the two is called a weather front. At a front, the two air masses have different densities, based on temperature, and do not easily mix. One air mass is lifted above the other, creating a low pressure zone. … Fronts are the main cause of stormy weather.

What are the types of air

There are four categories for air masses: arctic, tropical, polar and equatorial. Arctic air masses form in the Arctic region and are very cold. Tropical air masses form in low-latitude areas and are moderately warm. Polar air masses take shape in high-latitude regions and are cold.

What causes the movement of air mention three reasons

Wind is the movement of air. … Three of the major factors that affect wind are pressure gradients, the rotation of the planet, and friction. … Wind travels from areas of high pressure to areas of low pressure.

What is the horizontal movement of air is called

Wind is the horizontal movement of air across Earth’s surface.

What does something is in the air mean

What is the description of air

Air is a mixture of many gases and tiny dust particles. It is the clear gas in which living things live and breathe. It has an indefinite shape and volume. It has mass and weight, because it is matter. The weight of air creates atmospheric pressure.

How does air movement affect weather

The way the air moves affects the weather, because winds move heat and cold temperatures as well as moisture from one place to another, transporting conditions from one geographical zone to another. The way winds pass each other, and the direction they move, also affects what weather a region will see on any given day.

How temperature differences result in the movement of air

Changes in the surface temperature heat or cool the air above, which leads to air movement (wind). … Solar heating of the Earth’s surface is uneven because land heats faster than water, and this causes air to warm, expand and rise over land while it cools and sinks over the cooler water surfaces.

What is the full meaning of air

How do you describe the movement of air

The Movement of Air. Movement of air caused by temperature or pressure differences is wind. Where there are differences of pressure between two places, a pressure gradient exists, across which air moves: from the high pressure region to the low pressure region.

Where does moisture in the air come from

Water vapour enters the atmosphere primarily by the evaporation of water from the Earth’s surface, both land and sea. The water-vapour content of the atmosphere varies from place to place and from time to time because the humidity capacity of air is determined by temperature.

Do we use the with air

Air is an uncountable noun. However, ‘the’ (the article) precedes the word ‘air’. For example: He hit a ball in the air.

What two factors affect the movements of air masses

Is hot air high or low pressure

Warm air rises, creating a low pressure zone; cool air sinks, creating a high pressure zone. Air that moves horizontally between high and low pressure zones makes wind. The greater the pressure difference between the pressure zones the faster the wind moves. Convection in the atmosphere creates the planet’s weather.

What causes air movement between the land and the ocean

A sea breeze occurs due to the difference in temperature between the ocean and the land. As land heats up during the afternoon, air above it begins to rise forming a low pressure area near the land. Then cool air, situated in high pressure areas, spreads across the water and moves in over land.

Do we say on the air or in the air
