Rock Characteristics
This can cool, harden and form igneous rock.
What is magma or lava?
These rocks have little pieces of rocks, pebbles, mineral grains, and shell fragments.
What are sedimentary rocks?
True or False. Minerals are pure substances.
What is true? Minerals do not have anything mixed in.
Name the three types of rock groups.
What is Sedimentary, Igneous and Metamorphic?
Name two ways people use rocks.
What is buildings, walls, roads, jewelry, decoration, countertops?
This type of rock can have fossils in it.
What is a sedimentary rock?
These rocks can be formed by a volcano.
What are igneous rocks?
Name a way minerals can be grouped.
What is color, hardness or luster?
Igneous rocks sometimes have small holes in them. This is usually the cause of the holes.
What is trapped gas bubbles?
This can happen if igneous rocks cool slowly.
What is have a rough or bumpy texture?
This type of rock could have been a sedimentary or igneous rock before it changed.
What is a metamorphic rock?
These 2 things cause metamorphic rocks to form.
What are heat and pressure?
True or False. Minerals can have fossils in them.
What is false? Minerals are pure substance.
This is a solid that is pure (nothing is mixed in).
What is a mineral?
This can happen if igneous rocks cool fast.
What is have a smooth texture?
Explain a characteristic of a sedimentary rock.
What is made up of sediments from extreme pressure?
Explain the process for igneous rocks to form.
Igneous rocks are formed with extreme heat like from a volcano. The lava or magma will cool then harden.
Name a way minerals are different from rocks.
What is minerals are pure, minerals are inorganic..?
A hard substance composed of one or more minerals.
What is a rock?
The process of rocks changing from one kind of rock to another kind of rock over long periods of time.
What is the rock cycle?
Name a characteristic of an igneous rock.
What is formed from lava or magma, can have a rough texture, can be dark in color, can have small holes in it?
Explain the process by which sedimentary rocks form.
Sedimentary rocks are formed with extreme pressure. Over time, sediments like fossils, rocks or shells press together to form layers.
Minerals are inorganic. What does this mean?
What is minerals are NOT made from living things?
This can happen if an igneous rock cools VERY quickly.
What is look glassy?
What happens if an igneous rock weathers? What rock does it turn into?
