Answer:
For example, air with a large amount of water vapor is less dense than dry air because the water molecule has less mass than either an individual nitrogen or oxygen molecule. Also as elevation or altitude increases, air becomes less dense. Unequal heating of the Earth's surface also forms large global wind patterns
Explanation:
Yes, fish can sleep! Fish do not have eyelids to close, so they sleep with their eyes open. Depending on the species, fish can sit on the floor of a bowl, for example, to sleep. Others drift close to the bottom.
B because... Batteries are a source of chemical energy and chemical goes to electrical because the electrical energy goes through the circuits and then lastly, the electrical energy transforms into wind energy (mechanical energy)
The given statement is True.
In mineralogy, fracture refers to the shape and texture of the surface of the rock produced when a mineral is fractured. Minerals generally exhibit a highly distinguishing fracture, making it the main character used in their determination.
Fracture varies from cleavage, in cleavage clean splitting along the plane of cleavage takes place in the mineral's crystal structure, which is in contrast to more usual breakage.
