The Earth is one of eight major planets and a host of minor planets that circle a fairly average‚ middle-aged‚ main-sequence star. It formed from the accretion of residual material from the gravitational collapse of the solar nebula that produced the Sun. Based on their specific distances from the Sun‚ the planets formed into groups of similar chemical compositions‚ sizes‚ and densities. The four smaller inner planets are of higher density and are composed of a mixture of rock and metal. In contrast

something survives and flourishes throughout time. The movie encourages change to make the Earth sustainable again. The depletion of natural resources‚ the lack of attentivness‚ and the lack motivation in the human race are ways that have made the Earth unsustainable for humans. If the human race does not change and solve their problems effectively‚ it is a great possiblity that the world will turn into the barren planet from the film‚ and be forced to live on a cold ship in space. The depletion of the

What are the origins of life on Earth? This question has been highly debated by scientists for a long time. Scientists are trying to determine what makes Earth so unique that life thrives here but in no other planets that we are aware of. There are several theories that scientists have proposed in trying to determine the origins of life on Earth. Some theorize that life derived from an extraterrestrial source‚ others believe autotrophs were the source‚ and other groups hypothesizes that heterotrophs

MANKIND KILLING OUR PLANET. Our planet contains a variety of landscapes‚ forests and different climates. Over the years it has gone through many changes in its climate and the species that live on it. Now it seems that our planet is being detrimentally transformed‚ not by natural events‚ but by the actions of one species-mankind. Are we as humans changing planet earth? The facts certainly show that there has been a change in climate and that it is Human induced. It has become noticeably hotter

Paper C: Reaction to article How I (Almost) Saved the Earth By: S. Adams Richard R. Powers Environment & Society 21432 M-W 12:00PM There are a lot of factors when considering building a “green” home. In Adams’ article “How I Almost Saved the Earth‚” he states that the greenest house any one could ever build is a house that is never built. This is true‚ but to most people this will not be a reasonable way to spend their lives. Therefore‚ if one wanted to build a house with the least

How we can protect marine life from extinction Extinction means that the loss of species or other taxonomic unit occurring when there are no surviving individuals elsewhere. Every species however small may have an important role in maintaining a well-balanced ecosystem. Recent surveys suggest that the number of species in an area may enhance ecosystem productivity and stability; hence the loss of any species could be detrimental to the ecosystem. Direct effects and indirect effects as a result
