The process of cooling and crystallization is when a molten rock is cooled and the minerals from the other rocks (like sand) plus weathering and/or erosion causes the rock to form shapes and create different minerals. <span />
1)Evaporation is a classification of vaporization that emerges on the surface of a fluid(liquid) as it shifts into the vapour phase. The surrounding gas must not be saturated with the evaporating material. When the molecules of the fluid(liquid) collide, they switch energy to each other based on how they collide with each other.
2)Condensation is the alteration of the physical state of matter from the vapour phase(gas) into the fluid(liquid) phase and is the reverse of vaporization.
3)Time perception.
4)A
5)B & D
6)Human activities provide to climate change by effecting modifications in Earth's atmosphere in the percentages of greenhouse gases, aerosols (small particles), and pollution(fog). The vastest known contribution comes from the burning of fossil fuels, which sends packing carbon dioxide gas to the atmosphere.
