How Does Earth Form?
Earth is the only surviving astronomical object with continents, oceans and atmosphere, which also supports and harbors life. Only the Sun can produce light that will reach the planet Earth. The planet’s average surface temperature is around minus 0.56 degrees Celsius or cold, but it varies between minus zero degrees, with a cold minimum and cold maximum. It is a world with continents, seas, oceans, forests and deserts. Some of its most important geographic features are equator, orbit of earth, satellites and atmosphere.
The planet earth orbits the Sun within a gas and dust atmosphere, revolving around it at an average distance of about 4.6 Astronomical Units (au). It is the outermost planet in the solar system and has been in existence for at least four billion years. It is one of the oldest known planets in the solar system and was probably created in its current form by solar-system debris. The composition of this planet is remarkably similar to that of its older and larger counterparts like comets and asteroids. It is composed mainly of rock, along with some water and organic molecules.
The composition of the earth consists mainly of rock, including sandstone, granite, Marble, and Limestone. Some igneous minerals, like gold and silver, occur as fine grains in the soil, while gypsum, an igneous rock, occurs as liquid. The earth crust is tectonically active, moving north and south poles and bringing continents together to form oceans and landmasses. At present, about four percent of the earth’s surface area is covered by water, with about another four percent being covered by either ocean beds or solid sediments. Volcanoes and other geothermal sources also contribute to the volume of earth crust.
There is a great deal of debate between creationists and evolutionists over whether or not the earth was created in its present form or, more importantly, how it was formed. Many creationists believe that there is evidence that the earth was created in its current state, with all its current features, at least a few million years ago. They argue that all of the earth’s continents are considered to be old, since no signs of erosion have been found, as compared to the lack of evidence for a recent rapid climate change on earth. Furthermore, they claim that there is enough evidence to suggest that there has been a great amount of global warming in the past century, though the evidence is somewhat disputed.
Evolutionists’ answer to how the earth formed is that it is, in fact, made up of several different pieces. The first piece, the core, is composed mainly of solid rock, with only a little water and organic compounds, such as nitrogen and carbon dioxide, existing. Evidence of the Earth’s hydrosphere can be seen throughout the world. Hydrospheres act as ponds holding melted rock, while hydrothermal vents create gases that rise to the earth’s surface.
The Earth’s upper mantle also acts as a stage for the formation of the lithosphere, which consists primarily of rock. The Earth’s outer layer, referred to as the stratosphere, holds a great amount of dust, as well as many pollutants. The thinning of the Earth’s crust, caused by plate tectonics, can be seen by the decline in the number of volcanoes over time. The stratosphere and the lithosphere, which hold two-thirds of the earth’s total weight, continue to circulate air and water around the earth, causing convection and heating effects, among other natural processes, to affect the Earth’s environment.
