EARTH SCIENCE 1.1

The parent rock of metamorphic rock is called:

• Matrix

• Protolith

• Sediment

• Magma

Igneous rocks are most abundant in:

• Continental interiors

• Oceanic crust
  

• Deserts

• River deltas

Sedimentary rocks are especially important because:

• They make up most of Earth’s crust
  

• They preserve Earth’s history and fossils
  

• They are the hardest rocks
  

• They cannot erode

44. Which rock type is most likely to form petroleum reservoirs?

• 44. Volcanic glass

• 44. Igneous

• 44. Metamorphic

• 44. Sedimentary

45. Which igneous rock forms oceanic crust?

• 45. Basalt

• 45. Rhyolite

• 45. Gabbro

• 45. Granite

46. Which rock is often used as a building stone because of its durability?

• 46. Shale

• 46. Basalt

• 46. Granite

• 46. Coal

48. Metamorphic rocks with aligned platy minerals are:

• 48. Vesicular

• 48. Glassy

• 48. Foliated

• 48. Non-foliated

49. Rocks that cool so quickly they form volcanic glass are:

• 49. Basalt

• 49. Diorite

• 49. Granite

• 49. Obsidian

50. The rock cycle demonstrates that:

• 50. Rocks only form once

• 50. Rocks never change

• 50. Rocks form only from magma

• 50. Rocks can transform between types endlessly

3. Which internal process creates new crust at mid-ocean ridges?

• 3. Subduction

• 3. Seafloor spreading

• 3. Weathering

• 3. Folding
