This a branch of science that relates to everything having to do with the earth and its atmosphere. It is the study of the physical characteristics for both inside and outside of the earth and everything that surrounds the earth as atmosphere, as well as hydrosphere and biosphere.
Every action and reaction involving the earth is part of earth science.
Earth science is the study of almost everything on earth that affect our lives. From meteorologists studying and predicting the weather to seismologists letting us know about earthquakes, we expand our knowledge about the earth that is our home.
The study of earth science is a fascinating trip through a number of fields. A few that are most notable include: geology, the study of rocks and minerals; paleontology, the study of fossils and dinosaurs; meteorology, the study of the weather and our atmosphere; and oceanography, the study of earth’s oceans.
Iron and nickel. The earth’s core is made up of a complex set of layers with the center made of nickel and iron and then extending 1,400 miles. There are other elements found in smaller amounts such as platinum, uranium, and gold.
The Pacific Ocean. It is 62.46 million square miles. At 13,000 feet/4,000 meters, tt is also considered to be the deepest ocean in the world and takes up 30% of earth’s surface space.
Scientists have developed new ways to measure heat and have found out that the core of the earth is around 1,000 degrees hotter than the sun. The sun’s surface is 5,500 degrees C/10,000 degrees F.
Magma. Once the molten rock has come to the surface in an eruption it is called lava.
Australia. The Great Barrier Reef is the world’s largest coral reef system. It consists of over 900 islands and 2,900 individual reefs extending over 344,400 square km/133,000 sq mi. It is off of the coast of Queensland, Australia and is so large that it can be clearly seen from space.
Found in America’s state of Arizona, the Grand Canyon is often thought of as one of the 7 natural wonders of the world. It is 277 mi/446 km long and stretches to 29 km/18 miles in length.
A geologist studies all forms of matter that make up the earth including solid, liquid, and gaseous substances. While they are known for studying rocks, they must also have extensive backgrounds in biology, chemistry, physics, and other sciences.
Diamonds. Over a long period of time, graphite and other carbonate rocks that are found in earth’s mantle can be changed into diamonds.
Known as Mount Everest, in Nepali it is called Sagarmatha and the Tibetans call it Chomolungma. Located on the international border of China and Tibet, it is 29,029 feet above sea level.
