Summary:        This week in science we finished our Geologic Time Project where each student researched a certain era on the Geologic Time Scale and created an interactive poster about that era. The era that I chose to create a poster about was the Cenozoic Era. This project was very research intensive as almost half the project was spent on research. The types of things that we researched about our era's were the climate in the era, the geologic events of that era, the position of continents during that era, and much more. The climate in the Tertiary period of the Cenozoic Era was mainly warm. In the Quaternary period however, there was a change in the environment as the climate of the Earth began to cool. In result of this, there was a series of ice ages during the Quaternary Period. Although eventually the climate began to warm up and become what it is today. The main geologic events that occurred throughout this era are the formation of the Himalaya Mountains and the Tibeta

Homo Sapiens: 15,000 Years Ago by Neil R Summary:        "The geologic time scale uses events, or huge things that have happened, instead of years to refer to different sections of Earth's history." as said in the article titled "Tic-Toc-Time" by Rocketlit. Geologic time is split into three types of measures of time, those measures being eons, eras, and periods. One era in the geologic time scale is the Cenozoic Era. One important thing to note about the Cenozoic Era is that it is the current era that we (humans) are living in. This era is split into two different periods, the Tertiary period and the Quaternary period. The Tertiary period lasted from 66 million years ago to 1.8 million years ago. The Quaternary period has lasted from 1.8 million years ago to present time. The major events that occured in the Cenozoic Era is the rise of the homo sapiens (humans) which occurred and is still occuring in the Quaternary Period. Other major events are the afte

Rockcycle by Woudloper/Woodwalker Summary:        The rock cycle is the process in which rocks are broken down and transformed into other rocks. These rocks are igneous rocks, sedimentary rocks, and metamorphic rocks. Igneous rocks form when molten material from beneath the Earth's surface cools and hardens.  Sedimentary rock is made of sediments that have been deposited and then pressed together to form solid rock. Lastly, metamorphic rock forms when an existing rock is changed by heat, pressure, or chemical reactions.  One interesting fact about the rock cycle is that one of the stages of the rock cycle, magma is around 1000 degrees celsius. Magma is the result of when rock melts deep underground. Also, the type of rock that is formed from underground crystallization of magma is an intrusive igneous rock. At the same time, extrusive igneous rock forms when magma crystallizes above ground. Lastly, sedimentary rocks are formed form when sediment goes through lithification a
