Answer. A. Elevation and prevailing winds.
Which two factors affect the growth of vegetation?
The two factors on which the growth of vegetation mostly depends are— temperature and moisture.
What affects the highland climate the most?
The climates in the highlands are mostly affected by the level of precipitation that it received on an annual basis. The highland climates are mainly controlled by the polar and the artic masses which provide and influence with a great diversion to its temperatures, subtypes, diversity in the landforms, and life.
What causes variation in the highland climate?
Unique climates based on their elevation. Highland climates occur in mountainous terrain where rapid elevation changes cause rapid climatic changes over short distances.
What two factors influence the climate of a highland area?
In mountainous regions, altitude and insolation play important roles in controlling temperature and precipitation.
What are two factors of vegetation?
Answer: The growth of vegetation depends on two factors: temperature and moisture.
What are the factors that affecting vegetation?
There are four major factors which influence the nature and growth of vegetation. These are: climate, soils, nature of the surface, and man. Where the factors are favourable, plants grow well, where they are not, plant growth is slowed down.
What is the vegetation in the Highlands?
The highland vegetation is remarkable for the absence of trees, large tree-like shrubs, lianas, climbers, etc. Shrubs are generally confined to elevations immediately above the timberline or grow only in certain specially favourable localities at higher elevations where also they tend to become greatly dwarfed.
What type of vegetation occurs in a highland climate zone?
The vegetation in the highlands also varies with elevation. Forests and alpine tundra are the typical vegetation. Vast tundras reach as far as the eye can see. Tundras have no trees, and the soil a few feet below the surface is permanently frozen.
What is the climate in the Highlands?
The amount of precipitation in Highland climate depends on the elevation. Sometimes the land around the base of a mountain is dry, but snow may cover the top of a mountain. This happens because high mountains force warm air to rise, where it cools and creates precipitation.
What are two factors that cause variation in climate?
Geological records show that there have been a number of large variations in the Earth’s climate. These have been caused by many natural factors, including changes in the sun, emissions from volcanoes, variations in Earth’s orbit and levels of carbon dioxide (CO2).
What are the geographical factors of highland?
From the human perspective, the highlands present a very severe environment. Most of its harshness can be traced to only two factors, atmospheric pressure and temperature. Both are much lower than in adjacent lowlands, and the pressure of the atmosphere is probably near the long-term low limit for the survival of men.
Why are highlands so cold?
As you go to higher altitudes, there are less air molecules pushing down on you (lower pressure). When the pressure of a gas decreases, the temperature also decreases (the reverse is also true – when the gas pressure increases, the temperature increases). Therefore, the air temperature is lower at higher altitudes.
Why does temperature in highlands colder than in lowlands?
This hot air can indeed rise. But as it does, the atmospheric pressure decreases, the air expands, and it cools. So, even though they’re closer to the sun, thin air in the mountains keeps them colder than the thicker air in the lowlands surrounding them.
What is the climate and vegetation of Scotland?
Vegetation in Scotland. Boreal Cold winters, hot summers, dry, es- pecially in summer. Birch and pine dominant with hazel, and first appearance of mixed oakwoods. Atlantic Mild rainy winters, hot and fairly moist summers, with fre- quent drought.
Why do highland areas rain the most?
Why does most rain fall in the west? Highland areas receive more rain – many of these are in the west. Prevailing winds come from the south west carrying moisture from the Atlantic Ocean.
What are the 2 main vegetation controls?
There are three methods of Vegetation Control: mowing, trimming (often with mechanical equipment) and chemical.
What are the 3 natural factors that affect vegetation?
Climate, soil, the ability of soil to hold water, and the slope, or angle, of the land all determine what types of plants will grow in a particular region.
What are the effects of vegetation on climate?
Vegetation growth enhances heat transfer and increases the height of the Earth’s boundary layer, the lowest part of the atmosphere that is highly responsive to surface radiation. This increase in turn affects cloudiness and surface radiation.
How does climate affect vegetation?
Climate Stressors
Unfortunately, the changing climate increases stressors that weaken plant resilience, disrupting forest structure and ecosystem services. Rising temperatures lead to more frequent droughts, wildfires, and invasive pest outbreaks, leading to the loss of plant species.
What 2 geographic features make up the Interior Highlands?
Its three major topographic divisions are the Ouachita Mountains, Arkansas Valley, and Ozark Uplift. The three major topographic divisions of the Interior Highlands: the Ouachita Mountains, Arkansas Valley, and Ozark Uplift.
