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
