Rocks
The 3 main types of rocks
Igneous, Sedimentary and Metamorphic
What is the rock cycle
the process that describes how rocks change from one type to another
What is a mineral
A mineral is created by nature and forms the Earth’s rocks, and soils. They are inorganic
Which type of rock do we use to write in the classroom
chalk
What is a fossil
a preserved remain or trace of a plant or animal
How is Igneous rock formed
Through the cooling and hardening of Lava and Magma
What kind of rock forms from cooled magma
Igneous rock
Is a pearl a mineral
No. Pearls are made from Oysters, which means they are organic. Minerals are inorganic
What mineral do we use to flavor our food
Salt
Where are fossils most often found
Sedimentary rocks
How is sedimentary rock formed
Through the compression of mud, sand and pebbles pushed into layers
What happens to a rock that undergoes heat and pressure
It becomes metamorphic rock
What is the hardest mineral on the Mohs scale
A diamond
What do people use granite for in their kitchens
Countertops
What is paleontology
The study of Earth’s history through fossils.
How is metamorphic rock formed
Through heat and pressure applied to existing rocks
What is weathering and erosion
the processes that break down rocks into sediments.
Give 3 examples of minerals
quartz, diamond, Mica
What type of rock is used to build roads and sidewalks
concrete from limestone
What is fossilization
where the remains of an organism are preserved in sedimentary rock.
Which type of rock often contains fossils, and why?
Sedimentary rock because it forms in layers that can trap remains of living things
How can metamorphic rock become igneous rock again
It melts into magma and cools.
How many known minerals exist on Earth
3500
Look around the classroom—name one object that might be made from a rock or mineral
pencil tip (graphite), wall (gypsum/drywall), sink (granite)
Why is it important to study fossils
It is important to study fossils because it teaches us about what the Earth was like in the past.
