| One factor that determines the size of crystals is the rate at which magma or lava ________. | cools
🗑
|
||||
| Large crystals form when magma cools ___________ deep below the surface. | slowly
🗑
|
||||
| When magma erupts to the surface, it is called ______. | lava
🗑
|
||||
| A solid mixture of 2 or more minerals and other materials | rock
🗑
|
||||
| This type of rock forms from the cooling of magma or lava (Latin for "fire"). | igneous
🗑
|
||||
| This type of rock forms when particles of other rocks or the remains of plants and animals are pressed and cemented together. | sedimentary
🗑
|
||||
| This type of rock forms when an existing rock is changed by heat and pressure. | metamorphic
🗑
|
||||
| type of igneous rock that forms from lava that erupted onto Earth's surface resulting in fine grain or small crystal rocks. | extrusive
🗑
|
||||
| This type of igneous rock forms when magma hardens beneath Earth's surface resulting in large grain or large crystals. | intrusive
🗑
|
||||
| movement of rock fragments or particles by wind, water, ice, or gravity | erosion
🗑
|
||||
| process that presses sediments together | compaction
🗑
|
||||
| process in which dissolved minerals crystallize and "glue" particles of sediment together | cementation
🗑
|
||||
| small, solid pieces of rocks or other materials | sediments
🗑
|
||||
| process that breaks down rock and other substances of Earth's surface | weathering
🗑
|
||||
| process in which particles or sediments are laid down | deposition
🗑
|
||||
| process by which sedimentary rocks are formed | lithification
🗑
|
||||
| how metamorphic rocks are formed | heat and pressure
🗑
|
||||
| how igneous rocks are formed | melt into magma and then cools into igneous
🗑
|
||||
| What is sedimentation? | Another word for deposition
🗑
|
||||
| Why can fossils only form in sedimentary rocks? | They would melt in igneous rocks and be crushed too much with metamorphic rocks. Sedimentary rocks allow layers to pile on top of the creature after it dies so that fossils can be made.
🗑
|
||||
| Where is the oldest layer of rock located? | at the bottom (or deeper in the earth)
🗑
|
||||
| metamorphic rocks with lines | foliated
🗑
|
||||
| metamorphic rocks without lines | non-foliated
🗑
