Answer:
The heat equation can be written as. ∂ u ∂ t = α ∇ 2 u. where u(x, y, t) is the temperature field that varies in space and time, and α is the thermal diffusivity constant.
If the air temperature at sea level is 20 degrees Celsius, the temperature at 3000 meters will be approximately 7 degrees C.
Answer:
Areas or regions with low sea level or at sea level are called lowlands.
Lowlands are formed by deposition of lava through water, wind, or soil erosion and it has been said that such plains are more fertile for farming as compared to other high sea-level plains.
At Lowlands, people get opportunities for employment and the economy of the nation can be boosted.
For example, Lowlands of Scotland.
Farmers growing paddy or rice are getting the main benefits of Lowlands.
Lowlands have a suitable environment for many agricultural products.
Farmers can develop dairy farms and mountain farms.
