Chicken skin appears as red or white bumps that usually start to appear on the buttock, upper arms, legs or cheeks. These will often be rough and the skin that is covered in the bumps may be itchy. Because it is less humid during this time, the rash will often appear more frequently in the winter.
The principle of faunal succession is based on the four assumptions of (1) the validity of the principle of superposition; (2) the sequence of fossils are the same everywhere (3) rock layers of different ages will contain different types of fossils; and (4) the validity of the principle of original horizontality. î î î.
Establishment of organisms where no soil previously exsisted. Explain how primary succession can lead to soil formation on a newly formed volcanic landscape. Organisms decompose organic matter to create soil and the rock is physically weathered to become soil over time. Explain how a tsunami is generated along a subduction zone. An underwater earthquake causes rapid water displacement that turns into a tsunami.
