How do winds affect climate?
Wind carries moisture into an atmosphere, as well as hot or cold air into a climate which affects weather patterns. Therefore, a change in wind results in a change of weather. Wind travels from areas of high pressure to areas of low pressure. Additionally, heat and pressure cause the wind to shift direction.
What are the two advantages of northern mountains?
They save our country from the cold and dry winds of Central Asia, It also prevents the rain-laden monsoon winds of Indian Ocean from crossing over to Northern countries and causes heavy rain-fall in the Northern India.

What are the 3 factors that affect climate?
Introduction: Climate is determined by the temperature and precipitation characteristics of a region over time. The temperature characteristics of a region are influenced by natural factors such as latitude, elevation, and the presence of ocean currents.
What are the crops grown in hilly region?

How do mountains affect weather?
Mountains as rain makers and rain takers The mountains create a barrier to air moving eastward off the Pacific Ocean. The rising air cools as it moves up and over the mountains, and much of its moisture condenses, forming clouds and precipitation.
How do human activities affect the environment PPT?

What is importance of northern mountains?
By virtue of their high altitude, length and direction, they effectively intercept the summer monsoons coming from the Bay of Bengal and Arabian Sea and cause precipitation in the form of rain or snow. ADVERTISEMENTS: Besides, they prevent the cold continental air masses of central Asia from entering into India.
What is the climate of hilly region?
Describe the Climate of Hilly region. The Climate is moderate in Hilly region. It is hot in summer and cold in winter. Plently of rainfall takes place in monsoon season. Uttis, Salla, rhodendendron, etc are the natural vegetations.
Why there is more rainfall in hilly region?
They receive more rainfall than low lying areas because the temperature on top of mountains is lower than the temperature at sea level. Winds carry moist air over the land. As the air rises, it cools, and because cool air can carry less moisture than warm air, there is usually precipitation (rain).
Why do the northern mountains cause rainfall in our country?
Answer. The northern mountain ranges ( Himalayan Range) blocks the moisture bearing winds than crossing over and get into China , causing rainfall in our country.
What are the features of northern mountains?

Which human activity causes the maximum impact on the environment?
Global warming is arguably the greatest cause of impact on the environment. The largest of causes emanating through CO₂ levels from respiration to more detrimental causes like burning fossil fuels and deforestation.
How do mountains affect rainfall?
Mountains can have a significant effect on rainfall. When air reaches the mountains, it is forced to rise over this barrier. As the air moves up the windward side of a mountain, it cools, and the volume decreases. As a result, humidity increases and orographic clouds and precipitation can develop.
What are some examples of human activities?
- Martial arts.
- Underwater diving.
What are the two characteristics of climate?
The most familiar features of a region’s climate are probably average temperature and precipitation.
How are the northern mountains important for us?
The Himalayas also protect us from the cold winds blowing from the north. The Himalayas check the rain bearing monsoon wind and cause rainfall in various parts of our country. Many dams have been built in the Himalayan Rivers which provide electricity and irrigate agricultural lands.
