The Rock Cycle for 100 Define rock. Mixture of one or more minerals, rock fragments, volcanic glass, organic matter, or other natural materials. Push the Space Bar to check your answer.

The Rock Cycle for 200 Explain how rocks differ from minerals. Minerals are naturally occurring crystalline solids with definite chemical compositions. Rocks most often are mixtures of more than one mineral or other natural materials. Push the Space Bar to check your answer.

The Rock Cycle for 300 In the mini-lab using glue and coarse sand to represent rock formation, what did the glue represent? The glue represented minerals. Push the Space Bar to check your answer.

The Rock Cycle for 400 Compare and contrast igneous and metamorphic rock formation. Both form at relatively high temperatures. Igneous rocks solidify from melted rock material; metamorphic rocks begin and remain in the solid state as they form. Push the Space Bar to check your answer.

The Rock Cycle for 500 Verbally develop a poem that explains what can happen to a sedimentary rock as it changes throughout the rock cycle. Story must include a logical pathway through the rock cycle. Push the Space Bar to check your answer.

Igneous Rocks for 100 Explain the difference between magma and lava. Magma is molten rock below the Earth’s surface, lava is molten rock on the Earth’s surface. Push the Space Bar to check your answer.

Igneous Rocks for 200 Explain the difference between intrusive and extrusive igneous rock. Intrusive igneous rock is rock that forms from magma below the Earth’s surface. Extrusive rock is rock that forms from lava at the Earth’s surface. Push the Space Bar to check your answer.

Igneous Rocks for 300 The texture of obsidian is best described as glassy. Why does obsidian contain few or no mineral grains? Obsidian solidifies so quickly that there is no time for mineral grains to form. Push the Space Bar to check your answer.

Igneous Rocks for 400 Identify the property of magma that causes it to be forced upward toward the Earth’s surface. Magma is less dense than the surrounding rocks and is forced upward. Push the Space Bar to check your answer.

Igneous Rocks for 500 Granite, pumice, and scoria are igneous rocks. Why doesn’t granite have air holes like the other two? Because granite is an intrusive rock. Pumice and scoria form above ground where escaping gases can form bubbles in lava. Push the Space Bar to check your answer.

Metamorphic and Sedimentary Rocks for 100 What is foliation? How does it form? TUESDAY TRIPLE!! Foliation is the planar layering caused by the orientation and distribution of mineral grains in a metamorphic rock. Foliation is caused by pressure -induced deformation within Earth. Push the Space Bar to check your answer.

Metamorphic and Sedimentary Rocks for 200 During which process do minerals precipitate in the spaces between sediment grains? A. Compaction B. Weathering C. Cementation D. Conglomerate C. cementation Push the Space Bar to check your answer.

Metamorphic and Sedimentary Rocks for 300 What is a rock? How is rock different from a mineral? A rock is a mixture minerals, volcanic glass, organic matter, or other materials. A is a mixture; minerals are not. Push the Space Bar to check your answer.

Metamorphic and Sedimentary Rocks for 400 Explain how pieces of granite and slate could both be found in the same pieces of conglomerate. How would granite and slate pieces be held together? Granite and slate could be weathered in separate locations, then transported and deposited in the same location. Mineral cements would hold grains together. Push the Space Bar to check your answer.

Metamorphic and Sedimentary Rocks for 500 Marble is a common material used to make sculptures, but not just because it’s a beautiful stone. What properties of marble make it useful for this purpose? Marble is soft enough that it is easy to shape. It is composed of mainly calcite, which has a hardness of only 3 on the Mohs Hardness Scale. Push the Space Bar to check your answer.

Minerals #1 for 100 Define mineral. It is a naturally occurring, inorganic solid with a definite chemical composition and an orderly arrangement of atoms. Push the Space Bar to check your answer.

Minerals #1 for 200 Are diamonds made in a laboratory considered a mineral? Why or why not? No; because the diamonds are made in the lab, they are NOT naturally occurring. Push the Space Bar to check your answer.

Minerals #1 for 300 All minerals share the following characteristics EXCEPT that of… a. being formed by natural processes b. being formed from living organisms c. being solids d. having the atoms within the mineral arranged in a pattern b. Push the Space Bar to check your answer.

Minerals #1 for 400 Muscovite mica will peel off in flat sheets. This is an example of the physical characteristic called… cleavage Push the Space Bar to check your answer.

Minerals #1 for 500 If the cost of separating a mineral from waste rock becomes too great, the mineral may no longer be classified as an ore. This happens because… The mineral can no longer be mined for a profit. Push the Space Bar to check your answer.

Minerals #2 for 100 Define hardness. A measure of how easily a mineral can be scratched. Push the Space Bar to check your answer.

Minerals #2 for 200 A mineral is classified as an ore as long as… a. it is rare and beautiful b. it can be used as jewelry c. it is profitable and useful d. it is solid and natural 1. c. it is profitable and useful Push the Space Bar to check your answer.

Minerals #2 for 300 Describe how vein minerals form. Vein minerals form when minerals precipitate from fluids moving along faults or fractures. Push the Space Bar to check your answer.

Minerals #2 for 400 Describe how streak is used to distinguish between gold and pyrite. Rub the samples across a ceramic tile streak plate. Pyrite shows a greenish-black streak. Gold leaves a yellow streak. Push the Space Bar to check your answer.

Minerals #2 for 500 How would a collector of minerals determine the hardness of an unknown mineral specimen? A collector would use the Mohs scale of hardness and would use scratch tests against known minerals. Push the Space Bar to check your answer.
