Mutation. this happens when a cell copies its DNA to divide. its more common than you may think, a "typo" occurs every 100, 000 or so nucleotides, thats about 120, 000 "typos" every time a cell divides.
Transform boundary – this type of fault is found where two tectonic plates are moving alongside and parallel to each other mostly in opposite directions. This type of fault is also responsible for the rift valley and block mountains. No crust is destroyed nor new crust formed.
Convergent boundary – At this point, two tectonic plates are colliding because they are moving in opposite directions at each other. The pressure and stress of the collision force causes the plates to begin crumpling and folding at the boundary forming features such as fold mountains (an example is the Himalayas).
Convergent boundary – At this boundary , the denser of the two colliding tectonic plates (usually the oceanic plate) is subsided by the less dense one (usually the continental plate). The plate being subsided begins to melt as it does down into the mantle and becomes liquid rock. This magma rises through the fissures formed at the boundary and erupts into volcanic islands along the boundary.

<span>Water is considered an abiotic factor in the ecosystem because it is a non-living part of the ecosystem. Although water is abiotic, it has great impacts on both living and non-living things. Water is very important to al living things and no living organism can survive without it. Other abiotic factors in the ecosystem are soil, rocks, sunlight, oxygen, etc.</span>
