The inferred pressure and interior temperature at the boundary between Earth's outer core and inner core are 3.1 million atmospheres pressure and an interior temperature of 6300.

As we know, the crust and mantle are rich in minerals. However, the Earth's core is mostly composed of iron and nickel metals. We also found iron-soluble materials called siderophils. These elements are completely uncommon in the earth's crust and, therefore, are called noble metals. In these precious metals we find cobalt, gold and platinum.

Another key element found in the atomic nucleus is sulfur. 90% of all the sulfur on Earth is in the core. The core is known as the hottest part of the entire planet. The internal structure increases temperature with increasing depth. However, given the distance of more than 6,000 kilometers that separates us from the surface of the Earth to the Earth's core, it is quite difficult to know at what temperature this center of molten iron and nickel is located. The temperature is not always the same. They fluctuate depending on pressure, Earth's rotation and the composition of the elements that make up the atomic nucleus.

Because convection currents cause materials to move, some material enters "new" into the core while others exits again and no longer melts. This is due to the proximity or distance of the materials from the center and their very high melting points.

General research says that the temperature of the earth's core From 4000 degrees Celsius to 6000 degrees, approx.

The formation of the Grand Canyon defies the explanations offered by evolutionary geologists. the have argued that fossil-bearing rocks were largely laid down in local floods by rivers dumping sediments into waters.

The Grand Canyon, also known as Gran Caón del Colorado or Gran Caón de Hopi (Hopi: ngtupqa, Yavapai: Wi:kai:la, Navajo: Bidáá Haazti Tsékooh, Southern Paiute language: Paxa'uipi), is a steep-sided canyon cut by the Colorado River in Arizona, United States.

The Grand Canyon stretches for 277 miles, can be up to 18 miles wide, and can be more than a mile deep.

Grand Canyon National Park, Kaibab National Forest, Grand Canyon-Parashant National Monument, Hualapai Indian Reservation, Havasupai Indian Reservation, and Navajo Nation all encompass the canyon and surrounding rim.

Theodore Roosevelt frequently travelled to the Grand Canyon region to go hunting and take in the grandeur. He was a strong supporter of its preservation.

Uplift of the Colorado Plateau used to be a key step in the eventual formation of Grand Canyon.

The motion of plate tectonics lifted the rocks high and flat, creating a plateau thru which the Colorado River may want to cut down.

The sedimentary rocks uncovered for the duration of the canyon are prosperous with marine fossils such as crinoids, brachiopods, and sponges with various layers containing terrestrial fossils such as leaf and dragonfly wing impressions, and footprints of scorpions, centipedes, and reptiles.

The oldest rocks exposed in the canyon are ancient, 1,840 million years old.

1) Due to the war, this soldier knows of despair, death, fear, and fatuous superficiality cast over an abyss of sorrow.

2) The war has caused this soldier to experience physical and emotional trauma and to witness the senseless violence and destruction of war.

3) It is likely that this soldier’s experiences will make him less likely to want to become involved in any future wars, as he has seen firsthand the devastating effects of war and the emotional trauma it causes.

4) The two sentences of parts or sentences that I believe to be most powerful are: “What would our fathers do if we suddenly stood up and came before them and proffered our account?” and “Our knowledge of life is limited to death.” These sentences speak to the reality of war and the devastating effect it has on soldiers and their families. They capture the feelings of helplessness and sorrow that come with war, and the idea that war can take away the innocence of youth.

When lava reaches the Earth's surface via volcanoes or large cracks, the rocks that develop when the lava cools and hardens are known as extrusive igneous rocks. Some of the more frequent types of extrusive igneous rocks are lava rocks, cinders, pumice, obsidian, and volcanic ash and dust.

The most frequent form of volcano is a cinder cone. A cinder cone is shaped like a cone, however it is significantly smaller than a composite volcano. Cinder cones are seldom 300 meters tall, although they have steep edges.
