Pieces of solid material that have been deposited on Earth's surface by wind, water, ice, gravity, or chemical precipitation.

1

What is weathering?

1

What is deposition?

1

The process of weathering that causes weak minerals to break down and the strong minerals to separate from the weak.

1

The weathering process that causes rocks to break along fractures or boundaries.

1

A sedimentary rock and mineral fragment produced by weathering.

1

Erosion is the removal and movement of surface materials from place to place.

1

The main forms of erosion are:

1

Faster moving water affects deposition in what way?

1

Areas on the Earth where most sediments are deposited.

1

Lithification is the process when pressure and temperature from the bottom of a sedimentary basin began to compact sediments into sedimentary rock.

1

What substance maintains open spaces during lithification?

1

In Question 12, you were asked what mineral maintains open spaces during lithification. What can be found in these spaces?

1

Earth's crust's temperatures increase at about 30*C per kilometer.

1

What process forms sedimentary rock when mineral grains are stuck together into the rock?

1

What is type one cementation?

1

What is type 2 cementation?

1

The primary feature of sedimentary rocks.

1

Graded bedding is when inclined layers of sediment move forward across a horizontal.

1

Graded bedding is when the particles are gradually heavier and coarser towards the bottom.

1

The most well-known feature of sedimentary rock.

1

Parts of organisms cannot be replaced by minerals during lithification.

1

How are clastic sedimentary rocks formed?

1

What is porosity?

1

What rocks form from the minerals left behind after evaporation?

1

Evaporites are the layers of chemical sedimentary rocks that form as a result of precipitation from a supersaturated solution.

1

What are the 3 most common evaporites?

1

What rock is formed from the remains of dead organisms?

1

What are some primary uses of sedimentary rocks?

1

What changes occur when a rock becomes a metamorphic rock?

1

Where is the pressure for metamorphism found?

1

Temperature for metamorphism is derived from the sun

1

Grade is dependent on pressure, temperature, and depth.

1

Regional Metamorphism occurs when high temperature and pressure affect large regions of Earth's crust. What level grades can this include?

1

How are regional belts divided/classified?

1

Contact metamorphism is when molten rocks collide with a larger mass of molten rocks and come together.

1

Where are minerals that crystallize at high temperatures found [in relation to an intrusion]?

1

What metamorphism is the result of very hot water reacting with rock and altering its chemistry and mineralogy?

1

Minerals in wavy layers and bands that line up due to pressure are...

1

Minerals that form blocky crystal shapes are...

1

Porphyroblasts are

1

What might change a rock compositionally?

1

When water freezes in an open space in a rock and breaks it, what is the phenomenon called?

1

The biggest cause of erosion are glaciers.

1

How does lithification begin?

1

How can sedimentary rocks be energy sources?
