Carbon dioxide mainly comes from the burning of various fossil feels of power generated and transport use.
The reason the socks stick together, is because electrons from one fabric rub off onto another fabric by friction.
Answer:
There are four stages in the water cycle
1. Evaporation
Evaporation is the process by which water changes from a liquid to a gas or vapor. Evaporation is the primary pathway that water moves from the liquid state back into the water cycle as atmospheric water vapor.
2. Condensation
Condensation is the process by which water vapor in the air is changed into liquid water. ... The phase change that accompanies water as it moves between its vapor, liquid, and solid form is exhibited in the arrangement of water molecules. Water molecules in the vapor form are arranged more randomly than in liquid water.
3. Precipitation
When we talk about precipitation, we are talking about water that is falling out of the sky, this could be rain, drizzle, snow, sleet, hail or something rarer!
4. Collection
When water falls back to earth as precipitation, it may fall back in the oceans, lakes or rivers or may end up on land.
Answer:
False
Explanation:
When scientists speak of evolution as a theory they do not mean that it is a mere speculation. It is a theory in the same sense as the propositions that the earth is round rather than flat or that our bodies are made of atoms are theories. Most people would consider such fundamental theories to be sufficiently tested by empirical evidence to conclude that they are indeed facts. As a result of the massive amount of evidence for biological evolution accumulated over the last two centuries, we can safely conclude that evolution has occurred and continues to occur. All life forms, including humans, evolved from earlier species, and all still living species of organisms continue to evolve today. They are not unchanging end-products.
Evolution by natural selection is one of the best substantiated theories in the history of science, supported by evidence from a wide variety of scientific disciplines, including paleontology, geology, genetics and developmental biology.
