the Evolution of the Earth's Crust

Introduction Crustal formation begins with Hadean eon shortly after core formation and magma solidification (Allegre et al., 2008; Elkins-Tanton, 2008; Rudge et al., 2010). This process begins with the difference between the crust-mantle region and bulk silicate earth (BSE) reservoir. It is believed that it formed the first continuous crust (Allegre et al., 2008). However, the properties of the whole rock of the original Hadian crust are not conserved in known geological records and can only be estimated by isotopic analysis (Tessalina et al., 2010; Rizo et al., 2012).

2 The circle of the earth is part of the Earth at our feet. It is the Earth's crust and mantle. The Earth's crust is the outer layer of the Earth. We are standing at the top of the Earth's crust. The mantle is the layer under the Earth's crust. The inside of the earth is very hot. Scientists learned about the internal state of our planet from earthquakes and volcanoes. When a volcano erupts, it sends lava and rock to the ground. There is also heat and pressure inside the earth. A mountain is formed by this heat and pressure. 3 Our water ring contains all the water on the earth. Seas, rivers, lakes, streams and ponds are part of the water ring. Glaciers and ice caps on the earth are made of water. We depend on the earth's water to survive. All living things need to absorb fresh water. Animals living in the sea will provide food. Water can also be used to generate electricity. Part of our electricity comes from the power of water

An earthquake occurred in the Earth's crust. Earth's crust contains the level of the ocean floor to the surface of the earth, the ocean floor. The interior of the earth contains enormous energy. Some of this energy escapes through cracks and other volcanic activities, but most of it is stored inside the Earth's crust and is contained in the Earth's crust. An earthquake occurred at this time. In the form of seismic waves (such as ripples of water), the escape energy spreads radially from the fault in all directions. Seismic waves cause the Earth to vibrate as it passes through the Earth. When the waves reach the surface of the earth, they shake the ground and something above it, ripping houses and buildings.

The earthquake meant that the Earth's crust suddenly vibrated. An earthquake occurs when the surface of the earth and the crust begin to vibrate. A very large plate forms the crust. Pressures on these plates come from beneath the surface of the earth. The accumulation of pressure over the years can ultimately cause movement of the crust and cause an earthquake. Not all earthquakes can cause injury or injury. Most are very calm. About 1.5 million earthquakes occur each year, but destructive damage is only about 100 cases. There are earthquakes all over the world, but in most places they are not strong. For example, in the northeastern United States, strong earthquakes hardly occur. When marking on the world map where earthquakes occur frequently, our markers form two large bands, the Pacific belt and the Mediterranean belt.
