The result is that the air is dry and it rarely rains. This explains why places like the eastern sub-Andean region of south America and the sonoran and Mojave Deserts of the western united states are extremely dry. Rain-shadow deserts tend to be mountainous because of the way they form, and they are associated with a number of mass wasting hazards such as landslides, debris flows, and avalanches. Warm air rises, and cool air comes in to take its place.
This movement creates different pressures in the atmosphere which creates the winds around the globe. Since the Earth spins, Condensation Condensation is the process by which water changes its state from a vapor or gas to a liquid.
Condensation is responsible for the formation of clouds. Common examples of condensation are: dew forming on How Clouds Form A cloud is composed of tiny water droplets or ice crystals that are suspended in the air.
A series of processes have to happen in order for these water droplets or ice crystals to form into clouds in the Virga is rain that evaporates before reaching the ground. Raindrops form The Atacama is in the country of Chile in South America. In an average year, much of this desert gets less than 1 millimeter 0. Regional Climate The climate at a given location on Earth is the regional climate.

Places around the Equator experience warm weather all year round, but experience alternate periods of rainy and dry seasons.
Places near lakes may experience more snow in the winter, whereas places on continental plains may be more prone to hail, thunderstorms, and tornados in the summer. Learn more about regional climates with this curated resource collection. Weather is the state of the atmosphere, including temperature, atmospheric pressure, wind, humidity, precipitation, and cloud cover.
It differs from climate, which is all weather conditions for a particular location averaged over about 30 years. Weather is influenced by latitude, altitude, and local and regional geography.
It impacts the way people dress each day and the types of structures built. Explore weather and its impacts with this curated collection of classroom resources.
Rain is liquid precipitation: water falling from the sky. If the prevailing wind passes through a mountain range, warm, moist air is forced upwards. As it rises, it expands and cools. As colder air is not able to carry as much moisture, the water condenses out, falling as rain or snow.
