Convection occurs over a very very long time in the earth's mantle. Rock slowly gets melted down from the core, then shoots back up from volcanoes. The new rocks get buried by sand and sediments, and the process resets.
Answer:
Frameshift mutation is caused by the addition or deletion of a base pair in the DNA of a gene.
Explanation:
Frameshift mutation also known as a framing error or a reading frame shift.
Frameshift mutations are due to either insertions or deletions of nucleotides. This causes the entire DNA strand to elongate or to shrink in size.
There are two types of frameshift mutations.They are insertions and deletions. Insertions involve the insertion of one of more extra nucleotides into a DNA chain.
Several diseases have frameshift mutations like HIV, Crohn's disease, cystic fibrosis etc.

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.
