The Importance of Ocean Exploration. As soon as humanity existed‚ people were tempted to explore and discover everything around them. This invincible desire has led humanity on its way of discovering Earth. And it seems that our planet is totally explored‚ everything is revealed and there is no place where any man has not gone before (or any robot hasn’t recorded). The next step is outside Earth. After the first space flight humankind concentrated its attention on exploring the galaxy‚ searching

eventually formed limestone and other similar carbonate rocks. Preservation of marine invertebrate fossils provides evidence for a marine setting for the Paleozoic. Starting around 250 million years ago‚ the Mesozoic era‚ the earths crust rose due to tectonic shifts. This forced water out of the area leaving behind rock formations of salt and gypsum‚ this lead to the exposure of the former sea bed causing the rock to oxidize to the now characteristic red-orange color. The Paleozoic carbonates are dominantly

A metamorphic Rock can be formed by simply being under the earth’s surface‚ being exposed to extremely high temperatures and a huge amount of pressure from the layers of rock above. These rocks can be formed by tectonic processes‚ some which include‚ continental collisions (this is a process that causes friction‚ distortion and horizontal pressure). These rocks can also be formed when rock becomes heated rapidly by the intrusion of a hot molten rock‚ (called magma) and it comes from the earth’s interior

crust is made up of seven major plates and a number of minor plates. The plates move because of the convection currents in the mantle caused by temperature differences within the mantle‚ leading to volcanoes and earthquakes‚ the world’s major geophysical hazards. The movement of plates due to convection currents results in a variety of types of plate boundary‚ each of which gives rise to particular types of hazards. Constructive boundaries occur where two plates are moving apart. Basalt rises
