The WeatherOnline version Read the second part of the text The Weather. by My Project 1 The Weather In higher altitude places, the air pressure decreases because the air is less dense here. However, in lower altitude places, the air pressure increases because the air is denser at lower sea levels.Wind is caused by air flowing from high pressure areas to low pressure areas. The differences in the pressure is caused by the uneven heating of the Earth's surface by the sun. Some areas of the Earth receive more heat from the sun than other areas. This also results in various wind speeds. A difference between high and low pressure will cause wind, but the greater the difference the stronger the wind.The rotation of the Earth also has an effect on the direction of the wind. If the Earth did not rotate, the wind would blow in a straight direction. Since the Earth rotates, the wind is deflected from the straight path. 2 The Weather Local winds are created as a result of mountains, vegetation, bodies of water, and other similar natural bodies. This is why local winds may change often, from mild breezes to strong winds in just hours. Local winds cover short distances.There are several variables that affect the type of weather on the Earth, one is location. Coastal areas may have different weather patterns than mountainous areas. Weather also depends on a place's distance from the equator.In summary, the Earth's weather can be warm, cold, windy, dry, rainy, snowy, and different combinations of each. Temperature affects air pressure, wind has an effect on temperatures, and there are other variables affecting the type of weather occurring throughout the world.
