Continental drift is the theory which proposes that the world was originally made up of a single continent. With the passage of time, this continent was broken up, and it drifted apart to form the seven continents that are present today. It was proposed by Alfred Wegener whose hypothesis stands that the continents are made up of rocks that rest on the heavier weighing rocks on the crust, and this is a movement that is mimicked by icebergs on water. The continents move rigidly. Plate tectonics theory proposes that the Earth’s surface is actually broken up into a ...

Hawai'i was the 50th state to join the USA. It comprises 132 islands and is said to be the home of volcanic islands. These islands reside in the Central Pacific Ocean. Moana Loa is one of the top most active volcanoes that had formed the island of Hawaii in the ocean (Networks, 2016). The movement of plate tectonics has resulted in the volcanic eruption and, however, the volcano towering and presence of valleys had a significant impact on the economic value.

The continental plate in the eastern part of Asia is composed of various volcanoes and tectonic movements. Most of the volcanic rocks in this region are composed of alkali basalts with signs of continental contamination. There are various models that explain the region’s magmatic evolution. The two most common models used to explain the movements refers to the surficial processes and the other one refers to the deeper processes associated with the Pacific ocean plate. These two processes are antithetic and may hay happen subsequently. The volcanism can be traced by tomographic imaging that can be directly associated ...
1. Find a rock and a mineral each
Found Rock – Limestone
Found Mineral – Diamond
2. a. What type of rock is it?
Limestone is a sedimentary rock (“Limestone” 1).
b. What kind of mineral is it?
Diamond is an elemental, crystalline carbon mineral (Putnis 121).
c. Categorize the rock and mineral and try to find the names of the rock and mineral using the internet. The rock is a carbonate sedimentary rock (“Limestone” 1). The particular stone that I found is called a Coquina. Since diamond is made up of copper, it can be classified as a native metal element (Putnis 121). The ...
