3.1 1. Minerals have a few distinguishing characteristics that differ them from other materials. One of the biggest characteristic that minerals poses is they are naturally occurring, inorganic element or compound. Another is the hardness of the mineral. Minerals also have the characteristics of very different cleavage shapes. This is because minerals are easy to fracture. They also poses a crystalline structure. Rocks are a mixture of minerals, whereas minerals are their own purest form. Rocks also do not have crystalline structure. Rocks also can include fossils where minerals cannot. Minerals colors are generally the same. Rocks vary in color. 2 .The most significant difference between ingenious, sedimentary and metamorphic. Ingenious rocks are fire or …show more content…

There is one big reason rocks are not found on the sea floor that could be attributed to the dynamics of nature. One of them is because the sea floor is constantly changing thanks to seafloor spreading. So, the seafloor now is not the same as it was years ago. Seafloor spreading happens because of the earth’s plates constantly moving meaning the rocks on the seafloor will soon be shifted inward toward the mantel or shifted to another side. 2. The three types of plate convergences are convergent, divergent and transformative. Each has something different happen. In convergent, the two plates converge. In divergent, the two plates move apart. In transformative, the two plates slide across one another. 3. The dynamic nature of Earth basically means that the Earth is constantly changing and growing. This is majorly involved in the Earth’s ongoing recycling process. The process has been going on for billions of years. The crust basically acts in a cycle. Rocks are heated underneath the crust then pushed out through a volcano or the oceanic plate. The rock substance that becomes the crust will deposit back underneath the crust. All of the process can be credited to the dynamic nature of Earth.

The idea of catastrophism or “consecutive creations”, is the theory that changes earth’s crust geological history from sudden violent and unusual events. Catastrophism is the idea that Earth has been affected in the past by sudden, short-lived, violent events, possibly worldwide in space. This view holds that the present is the key to the past, and that all things continue as they were from the beginning of the

Explain How New Material Is Erupting Along Mid-Ocean Floor In The 1960's

457 Words | 2 Pages

In the 1960s, scientists found evidence that new material is erupting along mid-ocean ridges. The scientists dived to the ocean floor in Alvin, a small submarine that was built to withstand the pressures from four kilometres down in the ocean. In a ridge’s central valley, Alvin’s crew found strange rocks shaped like pillows. This rock can only form when molten hardens quickly after erupting under water. This is evidence that molten material has erupted over and over along the mid-ocean ridge.

How Did The Movement Of Plates Affect The Geological Features Of The United States?

273 Words | 2 Pages

The movement of plates affected the geological features of the United States via convection currents, plate boundaries, and natural disasters. Convection currents, or currents within a fluid (magma) that rise from convection (the rising of hot air and the falling of cool air) affected the geological features of the United States by moving the plates. The plates, rested just above the mantle, rely on convection currents below them to move them and form boundaries. This is where plate boundaries come into play. Plate boundaries are where plates either collide, separate, or bash against each other in opposite directions.

Explain How The Continents Moved To Drift Theory

622 Words | 3 Pages

However, this supercontinent didn’t stay as one for too long. Gondwana began to separate 170-180 million years ago. This was caused by continental drift which meant that the crustal plates of the earth were being dragged because of the movement in the deeper layer of rock in the mantle. Evidently volcanoes and earthquakes were two major factors in the movement of the continents. Black volcanic rocks known as Basalt excreted from the volcanic eruptions onto the sea floor in ocean areas which was called mid oceanic ridges.

How Does The Convection Drive Tectonic Plates

141 Words | 1 Pages

Plate tectonics is the theory that Earth's outer shell is divided into several plates that glides over the mantle. The tectonic plates acts like a hard shell, Which is the lithosphere. Plate tectonics’ theory was first proposed by a scientist named Alfred Wegener in 1912. He didn’t know how to explain that the continents could move around the planet, but the researchers can now. So why do the tectonic plates move?

Gondwan The Controversy Of The Continental Drift Theory

Such evidence as the jigsaw puzzle, glacial deposits, similar igneous rocks found on continents once connected and flora and fauna. But as technology evolved scientists were able to discover with seismometers and other technological devices that vibrations travelled through the tectonic plates causing Pangea to spilt and form Laurasia which drifted North and Gondwana which drifted to the South. Over the years these continents further spilt into even smaller continents slowly forming the continents we now recognise today which are still slowly drifting each year, hence ‘continental

Low Quality Marble

610 Words | 3 Pages

Simply put, marble is just limestone that has been exposed to heat and pressure for an extended amount of time. Because it is formed by applying heat and pressure over time, it is considered a metamorphic rock. Complexities arise when impurities are introduced to the limestone undergoing crystallization. Many things can change the mineral composition of marble, such as silica. When silica is present then carbonate minerals form masses of quartz or chert crystals, but only at lower temperatures of formation.
