Canyon is a big mystery. What we can say‚ is that its rock layers give us clues of how tectonic erosion occurred in the Grand Canyon. Some of those rocks can be age determined‚ but some can’t. Some of the rocks that can be age determined are the igneous rocks‚ and those rocks that can’t be age determined are the metamorphic rocks. The igneous rocks are one of the three main rocks. The metamorphic rocks arise from the transformation of existing rock types‚ which make changes due to heat and pressure

Lucky Koritela #23 The Rock Cycle The rock cycle begins when Earth’s plates shift around leaving gaps in between them making a volcano. The magma under Earth’s crust come through the gap and spill out of the volcano. Then the magma (lava) cools down and hardens into igneous rock. As time passes the igneous rock weathers (using substances such as water) away into little chips. After getting smaller‚ erosion (using elements such as wind) transports the little rocks to different places. The deposition

start with the origin of universe. it has been stated in The Big Bang theory. Over 13.5 billions years ago‚ a gigantic explosion produce energy and fundamental particle that created the universe. This mean that all the things that we see today such as rock‚ animal‚ plant‚ water was created during that time. First‚ quark is formed which is proton‚ neutron or electron. When all the quark was combined‚ it formed atom. Atom is then will form molecule and will produce solid‚ liquid and gases. Some quark are

Two general processes used to figure out the age of rocks is relative dating and radiometric dating. We will compare and contrast the strengths and weaknesses of both methods. According to Lutgens and Tarbuck‚ Relative dating is the process in putting events in their proper sequence. Relative dating is based on assumption‚ not able to give an accurate date but an estimated time period where the rock originated from. A Danish scientist‚ Nicolaus Steno is accredited for the Law of Superposition.

Metamorphic and Igneous Rocks of the Hudson Highlands 3rd Field Report Abstract The entire region of the Hudson Highlands underwent high-grade metamorphism‚ and at a series of locations different intrusions occurred during the Grenville Orogeny. Certain evidences to help back up this claim are the presence of gneissic rock and index minerals such as Siliminite and Garnet. Since the mineral composition indicates granulite facies‚ then its protolithic content is pelitic‚ meaning shale/mudrock. Also
