Igneous Rocks/ Rocks
metamorphic rock
Sedimentary Rocks
100
true or false : minerals are made of materials that were never alive.
What is True
100
One of the easiest way to identify minerals is by its: cleavage or color
What is color , but this is not the best way because just a small amount of a certain mineral can greatly change the color of a rock.
100
The creation and breakdown of rocks or recycling of rocks is called: erosion or the rock cycle
What is the rock cycle : The energy from the sun, the heat of the earth, and natural forces such as wind and water make enough power to create and change rock .
100
What are the rocks made up or igneous and sedimentary rocks that are changed: metamorphic, igneous-sedimentary
What are metamorphic rocks
100
What do you call pieces of earth or rock that have been deposited by water, wind or ice : sediments, magma, minerals
What are sediments
200
Most minerals are formed by what found inside the Earth : gas, magma, or lava
What is magma, the hot liquid rock inside the EArth
200
What refers to the color of the powder produced when a mineral is rubbed across white, unglazed porcelain(tile ) : streak, color or hardness
What is streak . The color of the streak is a better clue to the identity of the mineral than the color of the mineral itself.
200
How do scientist classify rocks : by how they were formed, or their color
What is how they were formed. : Three types Igneous , Metamorphic and sedimentary
200
Metamorphic means: many rocks or change of form
What is change of form
200
what is formed from many layers of sediment piled on top of each other : metamorphic, igneous , or sedimentary rock
What is sedimentary rock
300
The atoms of a mineral are arranged in regular patterns and form shapes called : rocks, crystals, natural gas
What are crystals
300
What is the term that refers to a mineral's shine: streak, luster, cleavage
What is what is luster: Luster is how shiny a mineral is when light hits it . The opposite of shiny is dull. Metallic or non metallic luster
300
How do igneous rock form : liquid magma, from sediments, or from coral shells
What is liquid magma
300
what are the two things needed for metamorphic rocks to change: sediments and lava, or heat and pressure
What is heat and pressure.
300
What layers of sedimentary rock are the oldest: top or lowest layers
What is lowest layers : the top are the newest
400
When magma cools quickly , minerals with what kind of crystals form: large or small
What is small, and when magma cools slowly large crystals form.
400
What is being measured by how easily it is to scratch the mineral using a fingernail, coin, or harder mineral: cleavage or hardness:
What is hardness; Scientist use the Mohs scale with a ranking of 1to 10 , 10 being the hardest. 1 being the softest.
400
The two types of igneous rocks are called: magma and molten or intrusive and extrusive
What is intrusive and extrusive : extrusive rocks form after they are ejected from a volcano, intrusive igneous rocks forms and cools more slowly because it does not reach the earth's surface.
400
pressure come from movement of the Earth's ; core, crust or mantle
What is crust : this often happens during the formation of a mountains
400
What is the process by which older rocks are broken down into small pieces: weathering or erosion
What is weathering .
500
What are the building blocks of rocks called: crystals, or minerals
What is minerals : the building blocks of minerals are crystals
500
What do you call the description of how a rock breaks: hardness or cleavage and fracture
What is cleavage and fracture. some rocks break easily into several pieces, other split into sheets, while others form cubes or split into right angles. The way a rock breaks is a clue to the minerals it contains.
500
One of the most common types of igneous rocks used in building and bridges is called: granite, malachite, pumice
What is granite it is an intrusive igneous rock
500
pressure can change shale to : emeralds, slate, granite
What is slate
500
Sediments are deposited Where: lakes and oceans, garbage dumps and rock piles ;
What are lakes and oceans: some sedimentary rocks are formed when remains of living things are deposited in layers(strata) . chalk is formed from small sea animals and shells, or when water evaporates rock salt and gypsum are formed.
