What determines the grouping of clastic sedimentary rocks?
Color
Size of the sediments
Mineral composition
Age
What is the main agent that causes erosion and removal of rock?
Fire
Water, wind, ice, or gravity
Earthquakes
Volcanic activity
What conditions are necessary for most metamorphic changes to occur?
Low temperatures and pressures
Elevated temperatures and pressures
High humidity and low pressure
Low temperatures and high pressure
What happens during contact metamorphism?
Rocks melt completely
Hot magma moves into rock
Rocks are eroded by water
Rocks are compressed by glaciers
Where are the conditions for metamorphic changes typically found?
On the Earth's surface
A few kilometers below Earth's surface
In the ocean
In the atmosphere
What usually results from contact metamorphism?
Major changes in rocks
Minor changes in rocks
Rocks melting into magma
Rocks being eroded by water
What is the role of hydrothermal solutions in metamorphism?
They cool the rocks
They provide heat and pressure
They are hot, water-based solutions that escape from magma
They erode the rocks
Which of the following is NOT one of the three major types of rocks?
Igneous
Sedimentary
Metamorphic
Volcanic
What type of rock forms when magma cools and hardens?
Sedimentary rock
Igneous rock
Metamorphic rock
Fossilized rock
What is lava?
Magma that cools beneath the Earth's surface
Magma that reaches the surface of Earth
A type of sedimentary rock
A mineral that forms under high pressure
What is the process in which rocks are broken down by water, air, and living things?
erosion
compaction
weathering
cementation
What is sediment?
Molten rock that forms beneath the Earth's surface
Weathered pieces of Earth materials
A type of metamorphic rock
The cooling liquid inside volcanoes
What type of rock forms when sediment is compacted and cemented?
Igneous rock
Sedimentary rock
Metamorphic rock
Basaltic rock
What happens to sedimentary rocks when subjected to high pressure and temperature?
They melt to form igneous rocks
They undergo weathering
They change into metamorphic rocks
They crystallize into new minerals
What is the result of slow cooling of magma?
Rocks with small, interconnected mineral grains
Large crystals forming in the rock
Rocks with a smooth, non-crystalline texture
A higher proportion of dark minerals
Which of the following would NOT be a major process in the formation of sedimentary rocks?
erosion
melting
deposition
compaction
The formation of igneous rocks is powered by
the sun
the rock cycle
erosion
Earth's internal heat
Metamorphic rocks that have a banded appearance due to the alignment of minerals are called
foliated
nonfoliated
clastic
glassy
