Q8. What type of vegetation is found in the regions which have extremely low temperature? Explain.
Answers
Answer:
Tundra is an area where tree growth is difficult because of cold temperatures and short seasons. Vegetation in tundra is limited to a few shrubs, grasses, and mosses. Scientists estimate roughly 1,700 different species live in the tundra, which isn't much compared to forests and grasslands.

Answer:
Vegetation covers a considerable portion of the earth and has an effect on weather and climate. Vegetation influences both albedo of the earth and the amount of water vapor and carbon dioxide in the air.
Why do I care? Humans are altering the vegetation on earth, and it is impacting weather and climate. Farmers and other community professionals might find it interesting to learn about the role of vegetation in weather and climate.
I should already be familiar with: Evapotranspiration and Evaporation, Earth's Energy Balance, Albedo, The Water Cycle
Vegetation includes all plants from evergreen forests to grassy meadows and cropland. All types of plants play a role in both the water cycle and the earth’s energy balance. They affect weather and climate mostly through evapotranspiration and albedo.
Effects on Weather and Climate
With vegetation covering about 20% of our planet, it’s no surprise that plants affect climate. However, it is surprising how much plants affect weather. Plants process and release water vapor (necessary for cloud formation) and absorb and emit energy used to drive weather. Plants also produce their own micro-weather by controlling the humidity and temperature immediately surrounding their leaves through transpiration. Most plants and forest soils have a very low albedo, (about .03 to .20) and absorb a large amount of energy. However, plants don’t contribute to overall warming because the excess warmth is offset by evaporative cooling from transpiration.
