Question
*Name three different abiotic factors that greatly influence vegetation patterns on Earth.
*As you travel across the United States from west to east along particular latitude during a particular time of the year, the majority of changes in vegetation patterns are due primarily to ____________ (Choose either temperature or precipitation) changes.
* Which side of a tall mountain is wetter – the windward or leeward side?
* Briefly explain why this is so, and state the name given to this effect
Explanation / Answer
Q1) Abiotic factors are the non-living Physical and chemical factors that affect the living organisms and vegetation on earth for growth, maintenance and reproduction. There are three main types of abiotic factors which influence vegetation they are-Temperature, light and moisture. The presence of light greatly affects the vegetation, as it helps in food production, temperature is related to light, water or moisture is also essential for growth of a plant, they help in preparing food material and maintain the growth of plant.
Q2)
When a person travels across the United States from west to east along particular latitude during a particular time of the year, the majority of changes in vegetation patterns are primarily due to ____________?
Answer- Precipitation.
Explanation:- The western part of USA is arid region, that is dry land it is the leeward side, where due to precipitation in windward side moisture is less, the root cause of aridness is due to less moisture in air, so there is less rain. But in east, it is moist land having adequate vegetation, as it falls in the windward side of the mountain, as air contains more moisture, more precipitation occurs this side, when the air reaches the top of the mountain the moisture label decreases or it has very less moisture content in it, so due to rain shadow effect there is very less rain in western region of USA. Which is a windward side.
Q 3) a)The wind-ward side of the mountain is wetter.
Q3) b)
The windward side of the mountain is wetter, because the mountain ranges acts as barriers to the flow of air across the surface of the earth. When warm air passes from a low valley area to the foothills of a mountain range. It rises along the slope of the mountain, due to higher terrain. When air is moving up the mountain slope, it keeps cooling when it rises by adiabatic cooling. This cooling results the formation of clouds, and gradually the, precipitation, which falls on the windward slope and as a result the windward side of the mountain is wetter. The windward side of the mountain is moist and filled with vegetation, this is due to earth's natural green-house effect. After that air moves downwards the slope, now the air is dry because when the air was rising in windward side the air had already shade most of its moisture, so now the moisture content of this air is very less, as a result the leeward side of mountain usually remains dry, this is called "rain-shadow effect"
