Round 1 Round 2

Layer Up! – 10 points • Earth’s thickest layer • Mantle Next Question

Layer Up! – 20 points • The layer of Earth composed of molten metal • Outer core Next Question

Layer Up! – 30 points • List Earth’s layers in order from the center out. • Inner core, outer core, mantle, crust Next Question

Layer Up! – 40 points • The part of Earth that is composed of the tectonic plates • Lithosphere (made of the crust and part of the mantle) Next Question

Layer Up! – 50 points • From where do scientists get their (1) DIRECT evidence and (2) INDIRECT evidence that shows that Earth is composed of layers… • (1) Direct evidence comes from actual rock samples taken from Earth (2) Indirect evidence comes from measuring seismic waves Next Question

Stay Classy! – 10 points • Igneous rock that cools inside Earth is called ___________, while igneous rock that cools outside Earth’s surface is called _____________. • Intrusive; extrusive Next Question

Stay Classy! – 20 points • When all the grains of a rock are large and easy to see, we say the rock has a _______ _______ texture. • Coarse grained Next Question

Stay Classy! – 30 points • You are observing a rock that was formed under great heat and pressure deep within Earth. Its minerals appear to be arranged in parallel bands. What type of rock is it? • Foliated metamorphic Next Question

Stay Classy! – 40 points • Extrusive igneous rock is most likely to have a ________-grained texture. WHY? • Fine; because it cools outside Earth’s surface and therefore cools so quickly that there is not time for large grains to form Next Question

Stay Classy! – 50 points • Intrusive igneous rock is most likely to have a ________-grained texture. WHY? • Coarse; because it cools inside Earth’s surface and therefore cools more slowly, giving time for larger crystals to form Next Question

You Sed It! – 10 points • When a rock fragment separates from the “mother rock” due to atmospheric conditions, we call it ___________. • Weathering Next Question

You Sed It! – 20 points • A piece of sediment has just gone through the process of deposition. What did it do? • It came to rest in a new place after eroding. Next Question

You Sed It! – 30 points • You are observing a rock that appears to have shell fragments cemented together. What type of rock is it? How do you know? • Organic sedimentary; made from cementation of remains of once-living things Next Question

You Sed It! – 40 points • State the 5 things (in order) that occur as a sedimentary rock is formed. • Weathering, erosion, deposition, compaction, cementation Next Question

You Sed It! – 50 points • You are observing a rock that has very large chunks of sediment compacted together. Classify this rock using at least 3 vocabulary terms. • coarse grained, clastic, sedimentary rock Next Question

Moh Knows Best – 10 points • The hardest known mineral is ___________ and it is given a value of ___ on Moh’s hardness scale. • Diamond; 10 Next Question

Moh Knows Best – 20 points • Which minerals on the table will scratch topaz? • Diamond & corundum Next Question

Moh Knows Best – 30 points • What will happen if you rub apatatie against a sample of fluorite? • Apatite will scratch fluorite Next Question

Moh Knows Best – 40 points • What will happen if you rub a mineral with hardness 4.5 against a sample of orthoclase? • The orthoclase will scratch the other mineral. Next Question

Moh Knows Best – 50 points • What minerals from the table could a penny scratch? • Calcite, gypsum, and talc Next Question

Round and Round We Go – 10 points • Rock that forms when another rock changes due to heat and/or pressure is called _________ rock. • Metamorphic Next Question

Round and Round We Go – 20 points • Weathering is a rock cycle process that takes place on the outermost layer of the earth, which is called the _______. • Crust Next Question

Round and Round We Go – 30 points • A typical sedimentary rock that forms when sediment such as sand cements together is called a ________ sedimentary rock. • Clastic Next Question

Round and Round We Go – 40 points • Convection currents occur in the ________ of the earth and result in hot/less dense rock ______ while cooler/more dense rock ______. • Mantle; rising; sinking Next Question

Round and Round We Go – 50 points • The part of the mantle in which convection is believed to occur is the ________. • Asthenosphere Next Question
