How do mountains affect the climate of a region?
(giving brainlist)
Answers
(Hope this helps!!!) Can I pls have a brainliest??
Answer:
As context, there are two sides of a mountain range:
A) The windward side
B) The leeward side
As mountains are tall, they block clouds which are in the troposphere. All the moisture thus falls onto the windward side, while almost none of the moisture from the rain gets to the leeward side.
In a nutshell, mountain ranges create barriers for precipitation which blocks off moisture to the leeward side, creating deserts.
This is why you see mountain ranges near deserts.
Give an example of the law of conservation of mass.
If ur correct i'll give brainliest.

Answer:
In a chemical reaction mass is neither created nor destroyed

Evolution means change in the physical features of an organism.
Explanation:
Evolution means change in the physical features of an organism. Evolution occurs in the population of an organisms due to various factors such as mutation, non-random mating and natural selection. Nonrandom mating occurs when an organism prefer mating with particular superior organisms or with the similar organism. Mutation in the genetic makeup of an organism is also responsible evolution. this mutation occurs when an organism experience ultraviolet radiation from the sun, or also occur if an error in DNA during cell division. Gene flow is also known as gene migration is the transfer of genetic material or traits from one population to another when the organism is migrated to another environment. Some organisms are selected naturally because they have the potential to survive in that environment so they survive and that doesn't adopt itself to the environment, it will extinct from the environment.
