Name:_______________________________________ Period:__________ Date:____________________ Earth Science in Action: Rocks Video Questions Word Bank fire rock cycle minerals organic intrusive igneous chemical density erosion extrusive sedimentary pressure weathering heat change sedimentary magma clastic metamorphic Video Time (1:49) 1) Rocks are composed of substances called ____________________. These come in different colors so rocks come in different colors. (2:28) 2) Rocks are continuously being created and destroyed; only to be turned into new rocks again. This is called the ____________ ____________. The three major types of rocks are _______________ rocks, ____________________ rocks, and ____________________ rocks. (2:52) 3) The word igneous comes from the Latin word “ignis” or _______________. Igneous rock starts out as _______________ inside the Earth. When it comes into contact with cooler surfaces it hardens into rock. ____________________ igneous rock is formed when magma exits the Earth in volcanoes, explosions, and lava flows. ____________________ igneous rocks form underground when magma cools and hardens slowly. (7:45) 4) Sand, mud, pebbles, and shells are brought together by wind and rain and over millions of years these sediments pile up on each other to make layers of _________________________ rock. When rushing sediments move they settle at different rates because of ____________________. (12:20) 5) There are different types of sedimentary rock. ____________________ rocks are rocks that are made of other rocks that are held together by a kind of natural cement. ____________________ rock is a sedimentary rock made up of things that were once living. ____________________ rocks form when large bodies of water evaporate and leave behind minerals in solid crystal form. (16:10) 6) Metamorphic sounds like the word metamorphosis, which means “_______________”. Metamorphic rocks are those formed by changes in existing rocks over time as a result of ____________________, _______________, and chemical reactions. (18:05) 7) Sedimentary and igneous rock can become metamorphic rock. Over time rain, wind, ice, and running water break down these rocks into smaller particles in the process of ____________________ and ____________________. These particles can become sedimentary rock again over millions of years. Metamorphic rock can become igneous rock again when it is reheated. This changing of rock continues to happen which is why we call it the rock cycle.
