I need to know what physical weathering and chemical weathering is for a science project!
Oksana_A [137]
Ok ok no fret im here to help as best as i can :)
Weathering is a process that breaks down or changes rocks into smaller pieces. Various atmospheric aspects are responsible for weathering processes. Weathering is different from erosion. Erosion is the movement of rock pieces and sediment from one area to another. Weathering is the breaking down of rocks and erosion is a wearing away of rocks. There are two main types of weathering: physical (or mechanical) weathering and chemical weathering. Quite often, both forms of weathering will occur together

Physical weathering is also known as mechanical weathering. This type of weathering occurs when rocks and other landforms are broken down by physical factors in the environment. These physical factors include wind, water, sun, ice and temperature changes

Consider the evidence that explains how physical separation of two populations of a species can cause speciation. What effect do
Tom [10]

Answer:

  • Interruption in the genetic flow between separated groups
  • The emergence of new mutations in each of the groups, and their accumulation in time. Slow and gradual differentiation between populations.
  • Genetic divergence by natural selection and reproductive isolation
  • Prezigotic isolation mechanisms

Explanation:

Allopatric speciation consists of the geographic separation of a continuous genetic background that can give place to two or more new geographically isolated populations. These separations might be due to migration, extinction of geographically intermediate populations, or geological events. In this speciation, some barriers impede genetic interchange, or genetic flux, as the two new groups that are separated can not get together and mate anymore. These barriers might be geographical or ecological.

The process of allopatric speciation involves different steps that affect organisms:

  • The emergence of the barrier.
  • Interruption in the genetic interchange
  • The occurrence of new mutations and their accumulation in time in each population. Slow and gradual differentiation.
  • Genetic divergence by natural selection and reproductive isolation makes it impossible for the two groups to mate even if the barrier disappears.
  • Prezigotic isolation mechanisms will be favored by selection if occurs a secondary contact between the new species in formation.
