What is the main method of heat transfer from the core to the crust of Earth?A) conduction
B) convection
C) insulation
Eliminate
D) radiation

Answers

Answer 1

Answer: The answer to this question is letter B. Convection.

>Mantle's convection is thought to make up about eighty percent of the internal heat flow to the surface, while the remainder originates in the crust.
>The main means of heat transfer is convection. This process requires that the substance can behave like a "fluid", and the earth's mantle does.

Answer 2

Answer:

The answer is

B

Convection currents raise the less dense hot material from the center to the cool crust and material from the cool (dense) crust settles down to the core to be heated again.

The correct answer would be option B

Natural Selection is a phenomenon in which the the traits that is advantageous for the population is common in a population.

These changes evolve over a period of time. The organisms having some change in the characters due to mutation survives and the organism lacking these features die.

These characters are then transferred from one generation to another and becomes common in a population.

The correct answer is B. Natural selection occurs through generations and is in which organisms best suited to their environment survive.
