Rock Test Review! Igneou s Rocks! Sedimentary Rocks! Metamor phic Rocks! Hodge Podge! Name that Rock!

100 - Q This glassy rock is made from lava that rapidly cooled in water.

100 - A Obsidian!

200 - Q These TWO rocks indicate that an explosive volcano once erupted there.

200 - A Pumice & Rhyolite!

300 - Q Granite & rhyolite are made of the same mixture of minerals, so… why do they have a different appearance?

300 - A Granite has larger crystals because it cooled slowly underground (intrusive). Rhyolite cooled quickly after a volcano erupted violently, it has smaller crystals. (extrusive)

400 - Q This igneous rock is formed from lava flows, and it dark, dense, and has more iron and less silica than some rocks. It forms the basement of the ocean floor. It has been found on the moon, other planets, and asteroids. What is it?

400 - A Basalt!

500 - Q List as many igneous rocks as you can!

500 - A 1.Granite 2.Basalt 3.Obsidian 4.Pumice 5.Rhyolite 6.Gabbro

100 -Q Many sedimentary rocks contain evidence of life called _________. These items are (OFTEN, RARELY) found in igneous or metamorphic rocks.

100 - A Many sedimentary rocks contain evidence of life called FOSSILS. These items are (OFTEN, RARELY) found in igneous or metamorphic rocks.

200 - Q This sedimentary rock comes from swamp plants and is an important source of energy.

200 - A Bituminous coal!

300 - Q This rock is made from mud or clay deposited in calm muddy waters of bays, shores, lakes, and marshes. It often smells earthy when wet. It may contain fossils. It can be light beige, reddish, brown, gray, or greenish, depending on the color of the mud!

300 - A Shale!

400 - Q Rocks like limestone, granite, and marble are mined in a ___________

400 - A Rocks like limestone, granite, and marble are mined in a QUARRY!

500 - Q List as many sedimentary rocks as you can!

500 - A Sandstone Limestone Gypsum Shale Bituminous coal Conglomerate Halite!

100 - Q Describe how metamorphic rocks form.

100 - A Extreme crushing and heating of rocks (incredible heat & pressure). Usually found in mountain building areas, near faults, or near magma or lava. Tectonic activity like folding, faulting, or compression of rock layers, & intrusion of molten rock causes orginal rock to get harder and with bigger crystals or bands.

200 - Q Metamorphic rocks form in areas of __________, ____________ and ______________ of magma.

200 - A Metamorphic rocks forms in areas of folding, faulting and intrusion of magma.

300 - Q Most fossils are found in rocks that are: SEDIMENTARY IGNEOUS METAMORPHIC

300 - A SEDIMENTARY!

400 - Q Where are metamorphic rocks found?

400 - A Metamorphic rocks are often found in areas of mountain building!

500 - Q List as many metamorphic rocks as you can and their originating rock!

500 - A Metamorphic Rock (Original Rock) Marble (limestone) Schist (slate) Slate (shale) Gneiss (granite) Quartzite (sandstone) Anthracite coal (bituminous coal)

100 - Q Which of these statements are true, and which are false? Use the legend to interpret the rock layers. Layer A was once a clear tropical sea. T / F Layer B is the location of granite. T / F Layer C was sandy, then buried, than magma flowed into it. T / F

100 - A Layer A was once a clear tropical sea. T / F Layer B is the location of granite. T / F Layer C was sandy, then buried, than magma flowed into it. T / F

200 - Q These are the cons of mining.

200 - A Environmental damage (loss of habitat, more erosion, causes soil, water, and air pollution). Health hazards (respiratory diseases, toxic chemicals in air and water, danger of falls and mine collapses). Violence/wars (fights over resources and to pay for guns/ammunition.) Easier to remove and use resources (more waste & rapid use of non-renewable resources.)

300 - Q This rock forms in warm shallow clear tropical seas and oceans.

300 - A Limestone!

400 - Q This rock forms from jumbled up rock that resulted from rapid burial in landslides and rockslides.

400 - A Conglomerate!

500 - Q These two rocks fizz when HCL is applied to them:

500 - A Limestone and Marble!

100 - Q Obsidian and anthracite coal are both shiny black rocks. How will you tell them apart?

100 - A Obsidian is harder and has conchoidal fracture! (Look at the edges.)

200 - Q Which word means you have enough of a mineral in a rock to make it profitable to mine? VEIN SMELTING ORE ALLOY

200 - A ORE !

300 - Q Marble and quartzite are both glassy and pretty. They come in similar colors. How will you tell them apart?

300 - A Marble is softer than quartzite and marble will fizz in acid.

400 - Q A rock is dark and dense, it has big crystals and a glassy appearance.

400 - A Gabbro!

500 - Q The most common category of rock found on the Earth’s SURFACE (where you stand) is sedimentary, and the most common category of rock found when you look at the ENTIRE Earth, is ____________________

500 - A The most common category of rock found on the Earth’s SURFACE (where you stand) is sedimentary, and the most common category of rock found when you look at the ENTIRE Earth, is IGNEOUS.
