Study Guide for Rocks and Fossils Assessment Test will be Tuesday, October 20th

Rocks and Fossils Study Guide

Assessment is on Tuesday, October 20^th

On the assessment, the students will be asked to:

·        label a diagram of the 4 parts of the Earth

·        “fill in the blank” questions

·        true and false statements

·        matching

·        knowing examples of the different rocks will be extra credit

            All of the below information comes directly from work that has been completed in class either independently, with a partner, or through discussions. 

v   There are 3 types of rocks.

v   Igneous rock is formed when melted rock from deep in the Earth cools and becomes hard.

v   Igneous comes from a word that means “fire.”

v   Some examples of Igneous rock are Pumice, Obsidian, and Basalt.

v   Sedimentary rock is formed when sediment is buried under ground.  There, they are pressed together into layers.

v   Sedimentary comes from a word that means “to settle.”

v   Some examples of Sedimentary rock are Shale, Limestone, Sandstone, and Conglomerate.

v   Metamorphic rock can be formed when one type of rock changes into another type of rock under lots of heat + pressure + time.

v   Metamorphic comes from a word that means “to change.”

v   Some examples of Metamorphic rock are Slate, Marble, and Gneiss.

v   Under the ocean, there are large plates, but not the kind you eat off of.

v   If these plates collide, there could be an earthquake or a volcanic eruption.

v   A fossil is made up of plant or animal remains that lived long ago.

v   It takes at least 10,000 years for something to become a fossil.

v   Fossils are found mostly in Sedimentary rock. 

v   Fossils give us clues to what the Earth was like long ago.

v   Sea creature fossils have been found in deserts, which means that there was once water there.

v   Layers of sediment build up over the dead plant or animal and eventually it turns into a fossil.

v   A paleontologist is a scientist who studies fossils.

v   Scientists have found groups of fossil footprints which means that these animals might have traveled in groups. 

v   Fossils can be found at the beach, in a new road that is being dug, or even on a mountaintop.

v   When a fossil forms, the soft part rots away and the hard part remains.

Good luck and let me know if there is anything you have a question about!!
