Question

On Darwin’s voyage, he observed ostriches and rheas living on grasslands on separate continents. These two types of birds are similar, but not identical. How did Darwin apply these observations?

Answer 1

• Heat energy is the result of the movement of tiny particles called atoms, molecules or ions in solids, liquids and gases. Heat energy can be transferred from one object to another. The transfer or flow due to the difference in temperature between the two objects is called heat.
