When the ground position of a front moves so that warm air occupies territory that was previously held by cold air, <u>It is knows a </u><u>warm front.</u>

<u></u>

  • The area where a warm air mass is replacing a cold air mass is known as a warm front.
  • The air behind a warm front is warmer and more humid than the air in front of it. Warm fronts typically migrate from the southwest to the northeast.
  • A warm front is a density discontinuity that is usually seen on the margin of an isotherm gradient that faces the equator and is situated at the leading edge of a homogenous warm air mass.
  • Since warm air is thicker and more difficult to remove from the surface of the Earth than cold air, warm fronts move more slowly than the cold fronts that typically follow them.

When Darwin got back from his voyage what did he do?
riadik2000 [5.3K]

Answer:

Charles Darwin spent almost 5 years in the voyage name  HMS Beagle. This voyage made him famous as after returning, he formulated the "Theory of natural selection" as he was amazed by the geographical distribution of the wildlife and also collected fossils that helped him to formulate his theory.

Explanation:

Charles Darwin was the main contributor to the theory of evolution. Besides, he was a geologist, naturalist, and biologist. He first demonstrated the branching pattern of evolution on the basis of natural selection. 18 February 1809 was his birth date and he died in 1882. He explained the theory of natural selection with the help of finches residing in the Galapagos island. The change in the beak structure of the finches according to the availability of food illustrates the process of natural selection and hence the process of evolution.
