The basic idea of star formation is gravitational collapse – the contraction of a region of gas under the influence of gravity. This is a simple process that would be expected to occur in any region of material dense enough for collisions between atoms to radiate away energy. However‚ the gas must be dense enough for collisions to occur and the temperature must be low enough for the atomic velocities not to be able to escape the system’s gravity‚ so star formation only occurs in a few areas.

Soil formation‚ or pedogenesis‚ is the combined effect of physical‚ chemical‚ biological and anthropogenic processes on soil parent material. Soil is said to be formed when organic matter has accumulated and colloids washed downward‚ leaving deposits of clay‚ humus‚ iron oxide‚ carbonate‚ and gypsum. As a result‚ horizons form in the soil profile. These constituents are moved (translocated) from one level to another by water and animal activity. The alteration and movement of materials within a soil

A. Definition of Back-Formation In etymology‚ back-formation is the process of creating a new lexeme‚ usually by removing actual or supposed affixes. The resulting neologism is called a back-formation‚ a term coined by James Murray in 1889. Back-formation is different from clipping – back-formation may change the part of speech or the word ’s meaning‚ whereas clipping creates shortened words from longer words‚ but does not change the part of speech or the meaning of the word. For example‚ the

The intent of this experiment is to demonstrate the formations of the world oceans and why they are salty. I hope to learn more about the formations of the world oceans and what causes the oceans to be salty. Based on my research‚ I know that if salty water was put on black paper and left outside in the sun‚ the water would evaporate but the salt crystals would stay. The salt would not evaporate because it is a solid. Knowing this I formed a hypothesis‚ being‚ if salty water was poured on black paper

theories then another scientists proves it wrong. I believe that the moon was formed from the big impact. The first theory is the co-formation theory. The co-formation theory also know as the condensation theory‚ says that the moon was formed at the same time as the earth. The theory states that the solar system was formed out of the solar nebula. The co formation theory explains why the moon appears to be in the location it is in. The weakness of this theory is because if the moon and the earth

People learn to hate‚ they can be taught to love‚ for love comes more naturally to the human heart than its opposite.” -Nelson Mandela.

Peat Formation Peat is a partially decayed organic matter laid down in anaerobic‚ or lacking oxygen‚ conditions in wetlands. Peat forms when plant material‚ usually in marshy areas‚ is inhibited from decaying fully by acidic conditions. It is composed mainly of peat moss or sphagnum‚ but also includes trees‚ grasses‚ and other marshland vegetation. It also includes many other types of organic remains such as fungi‚ insects‚ pollen‚ and on occasion dead animals. Peat formed in very wet conditions
