What is a sediment? A rock fragment

What is weathering? The break down of rocks and minerals

What are the two types of weathering? Physical and chemical

What is physical weathering What is physical weathering? When rocks are broken apart but not chemically altered.

What is Chemical weathering What is Chemical weathering? When rocks are broken down by being chemically altered (dissolved)

What is the difference between Breccia and Conglomerate What is the difference between Breccia and Conglomerate? Breccia has angular fragments and conglomerate has rounded fragments

What are the three main ingredients for all inorganic land-derived sedimentary rocks? Quartz, feldspar and clay minerals

What is the size range for a particle of sand? 0.006-0.2 cm

Which rock is formed from plant remains? Coal

Which rock can form as either a process of cementation or as a precipitate? Limestone

What type of sedimentary rock is Breccia? Clastic

What type of sedimentary rock is Coal? Organic

What type of sedimentary rock is Rock Salt Chemically formed (Evaporate)

What type of sedimentary rock is Sandstone? Clastic

What type of sedimentary rock is Limestone What type of sedimentary rock is Limestone? Bio clastic or Chemically formed (precipitate)

Define Lithification The process of turning sediments to stone

Define Bedding The way in which sediments are deposited in layers

Define Graded Bedding The largest sediments are on the bottom and the smallest ones are on top.

Define cementation The “gluing” together of sediments through natural means such as calcite build up.

Define evaporates Rocks that form as a result of the water that they are in evaporating (ex: salt water leaves behind the salty crust)

Which rock is made of particles that are 0.006 to 0.2? Sandstone

Which rock is made of particles that are 0.0004 to 0.006? Silt stone

Which rock is made of particles that are smaller than 0.0004? Shale

Which rock is made of pebbles and cobbles that are rounded Which rock is made of pebbles and cobbles that are rounded? Conglomerate

Which rock is made of pebbles and cobbles that are angular? Breccia

Which rock is made of Gypsum? Rock gypsum

Which rock is made of Halite? Rock salt

Define Foliated When due to pressure a rock exhibits shininess due to mica crystals or wavy bands as a result of realigning crystals

Define Contact Metamorphism When a rock is changed due to coming into contact with magma or lava.

Define Regional Metamorphism The rock changes due to the pressure from large regions of land smashing into each other.

Define Hydrothermal Metamorphism Rocks chemically changing due to an exchange of minerals (some new coming in, some old going out) caused by hot water and a chemical change.

What causes metamorphism? Heat and pressure

Which rock shows bands? Gneiss

What is a Gneiss geology joke What is a Gneiss geology joke? I might be gneiss but don’t take me for granite!

Which metamorphic rock will fizz in acid? Marble

Which rock is only fine grained and has regional metamorphism Which rock is only fine grained and has regional metamorphism? Slate or Anthracite coal

Which rock has a platy mica surface? Schist

Which rock has a microscopic mica crystals on its surface? Phylite

Which rock is a low grade metamorphism of shale? Slate

Which rock is the metamorphosed version of bituminous coal Which rock is the metamorphosed version of bituminous coal? Anthracite coal

Which rock is formed from contact or regional metamorphism and is made from limestone or dolostone? Marble

Which rock is formed from contact metamorphism and can be made from a variety of rocks? Hornfels

Which rock is formed from contact or regional and is made from quartz sand stone? Quartzite

Which rock is formed from contact or regional metamorphism is made from conglomerates? Metaconglomerate

Why would limestone dissolve in acid rain Why would limestone dissolve in acid rain? It is made of calcite which dissolves in acid.

Why would marble dissolve in acid rain Why would marble dissolve in acid rain? It is made of limestone which is made of calcite which dissolves in acid.

What does the rock cycle show you What does the rock cycle show you? Over time, any rock can become any other rock.

How do igneous rocks form How do igneous rocks form? The cooling (solidification) of magma or lava

How do clastic sedimentary rocks form How do clastic sedimentary rocks form? The cementation of deposited rock fragments

How do chemically formed sedimentary rocks form How do chemically formed sedimentary rocks form? They are either precipitate out of solution or are left as evaporates when the solution evaporates.

How do bioclastic sedimentary rocks form How do bioclastic sedimentary rocks form? Compacted organic materials such as plants or shell fragments.

How do metamorphic rocks form? Heat and/or pressure
