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.
