warm air/water both rise, produce convection currents, etc. The intense sunlight at the equator is absorbed by the earth’s surface, causing it to give off heat and warm the air above it. The air expands as it warms – becoming less dense – and rises, cooling as it does so. … This dry air produces a rain shadow.
Which landform creates the rain shadow effect?
Rain shadow deserts are formed because tall mountain ranges prevent moisture-rich clouds from reaching areas on the lee, or protected side, of the range. As air rises over the mountain, water is precipitated and the air loses its moisture content. A desert is formed in the leeside “shadow” of the range.
What determines the size of a rain shadow?
If the landforms are tall and wide enough to block or sufficiently delay the passage of these rain-producing weather fronts, most (if not all) of the humidity will be lost to precipitation over the windward side (also known as the rainward side) before ever making it past the top, and the air also forms foehn winds on …
What produces the rain shadow effect quizlet?
? An area having relatively little precipitation due to the effect of a topographic barrier, especially a mountain range, that causes the prevailing winds to lose their moisture on the windward side, causing the leeward side to be dry.
What is called the rain shadow area?
Hint: Rain shadow area is also called the leeward side of a mountain. It is the type of rainfall most common in mountainous areas. It is caused due to the physical structure of the area. Complete Answer: Rain is the precipitation in liquid form.
Where is a rain shadow effect most likely to occur?
Rain shadows are common on the western coast of the United States, where mountain ranges run parallel to the coast and perpendicular to the prevailing winds coming off the Pacific Ocean. The Great Basin of Nevada and Utah is in the rain shadow of the Sierra Nevada Mountains.
Which factor affects climate and creates a rain shadow?
The factors that shape weather and climate include the sun, location on Earth, wind, water, and mountains. Most of the moisture in the ocean air falls on the mountainside facing the wind. Little moisture remains to fall on the other side, creating a rain shadow.
What is a rain shadow area Class 9?
A rain shadow area is an area of dry land that lies on the leeward(or downwind) side of a mountain. High mountains act as barriers for cold or hot winds; they may also cause precipitation if they are high enough and lie in the path of rain-bearing winds. The leeward side of the mountains remains dry.
How do rain shadow areas receive water?
Rain shadow deserts are created when mountain ranges lie parallel to moist, coastal areas. Prevailing winds moving inland cool as air is forced to rise over the mountains. Carried moisture falls on slopes facing the winds. When the winds move over the crest and down the far side, they are very dry.
