Unit 1 Test Review

Density

100

What is the formula to calculate density

Density = Mass/Volume

200

If the density of an object is 36 g/ml and the mass is 102g, what is the volume?

2.83 ml

300

What is the density of water?

1.0 g/ml

400

How does the size and shape of an object effect the density of an object?

No change/effect

Same Material = Same Density

500

What is the relationship between Temperature and Density?

Hotter Temp = Less Dense

Colder Temp = More Dense

Latitude/Longitude

100

What is the name of the 0 degree line of Latitude

Equator

200

The Prime Meridian breaks up the Earth into two hemispheres. What compass directions are the two hemispheres?

East and West

300

What is the highest degree of longitude?

180

400

What city is someone in if the angle of Polaris is 45 degrees

Massena 

500

What is the latitude and longitude of Niagara Falls to the nearest degree?

43^o N, 79^o W

Mineral ID

100

What property is the first property you need to know when using the Mineral Flowchart?

Luster

200

What minerals bubble with acid?

Calcite and Dolomite

300

What mineral will scratch a penny but not glass, has no cleavage and is metallic?

Chalcopyrite

400

What is the difference between cleavage and fracture?

Cleavage - clean breaks - cut with a knife

Fracture- breaks apart randomly

500

What are two properties that would help you to distinguish between Halite and Calcite

Directions of cleavage (90 vs not at 90), reaction to acid, hardness, taste

Rocks

100

What is required for a rock to undergo metamorphism?

Heat and Pressure

200

What is an example of an evaporite? 

Rock Salt or Gypsum

300

What is the difference between and Intrusive and Extrusive Igneous Rock

Intrusive - Formed underground by magma - big crystals

Extrusive - Formed near the surface by lava - small crystals

400

What is the difference between contact metamorphism and regional metamorphism?

Contact - Touching - From Igneous rocks

Regional - Large area - From Tectonic Plates

500

What minerals are the first to crystalize in Igneous Rocks

Olivine and Calcium-rich Plagioclase Feldspar

Challenge

100

If a rectangle has the measurements of 35 cm, 15 cm and 20 cm and a density of 27g/cm³ what is the mass?

283,500 g/cm³

200

When Shale undergoes metamorphism, what is the pattern of rocks it goes through as it goes from low-grade to high-grade metamorphism?

Shale -> Slate -> Phyllite -> Schist -> Gneiss

300

What are the 5 requirements for an object to be a mineral?

1. Solid

2. Inorganic

3. Definite Chemical Composition

4. Naturally Occurring

5. Crystalline Structure

400

Explain why ice floats on water.

Ice is less dense since it expands when it freezes.

500

Explain how Graphite and Diamond are both made from Carbon but have very different properties.

Internal Arrangement of Atoms are different
