There are many different layers within the Earth. The core is at center of the Earth. The Earth’s core takes up sixteen percent of Earth’s volume‚ containing thirty-three percent of its Mass ..Pressure rises steadily inside the earth because of the weight of overlying rock. Therefore ‚the Pressure at the outer boundary of the core reaches 1.37 million atmospheres‚ 3.7 million Atmospheres. The core is made mostly of iron and nickel and possibly smaller amounts of lighter elements including sulfur

1. What transitions has Earth gone through and why? The young earth was anything but habitable. Radioactive elements decaying within its mass and impacts from debris raining down form space generated intense heat. There was no life during this era. Is called the Hadean era and was formed about 4.5 billion years ago. Hadean comes from the Greek word Hades which means “Hell”. That’s how hot the Earth’s temperature was. The next phase in the Earth’s history was the Archean era. It existed

The atmosphere of Earth is a layer of gases surrounding the planet Earth that is retained by Earth’s gravity. The atmosphere protects life on Earth by absorbing ultraviolet solar radiation‚ warming the surface through heat retention (greenhouse effect)‚ and reducing temperature extremes between day and night (the diurnal temperature variation).The common name given to the atmospheric gases used in breathing and photosynthesis is air. Dry air contains roughly (by volume) 78.09% nitrogen‚ 20.95% oxygen

begins to increase with altitude‚ and this trend continues in the thermosphere. Because the atmosphere in the thermosphere is so thin‚ a thermometer cannot be used to measure the temperature accurately and special instruments are needed. The Earth interior is divided into 4 layers. The properties of the Earth’s interior have been inferred primarily from earthquake waves. Distinct characteristics are found within each layer such as density‚ temperature‚ and pressure. OBJECTIVE: In this
