Rock Cycle
Name the 3 types of rocks
sedimentary, metamorphic, igneous
What are we standing on?
A tectonic plate
Are earthquakes predictable (similar to rain)?
No
Where are the most volcanoes found?
Ring of Fire
What is erosion?
rocks + landscapes crumbling and moving
magma or lava cooling forms...
igneous rock
When two plates push together, the boundary is called
a convergent boundary
At what type of boundaries do earthquakes happen?
All!
What are the two types of volcanoes?
Shield + cone
What is the difference between mechanical erosion and chemical erosion?
Mechanical is wind/water/air breaking apart rocks. Chemical is acids or water changing the composition of the rocks
heat and pressure changes one type of rock into
metamorphic rock
When two plates pull apart, the boundary is called a
divergent boundary
What causes an earthquake?
Convection currents build up pressure and eventually some rock breaks, allowing a plate to shift against another plate.
Or, Magma finally blows through a volcano, shaking the ground around it.
Are there active volcanoes near Brattleboro?
No
Our rock tumbler is an example of
mechanical erosion
deposition of small rocks, compaction, and cementation creates
sedimentary rock
When two plates slide past one another, it is a
transform boundary
What Greek myth explained earthquakes?
Minotaur
What type of viscosity of lava forms cone volcanoes?
High viscosity
What is the vocab word for land slides or other fast erosion events?
mass wasting
Intrusive rocks form when
magma cools and hardens inside the earth
yes
What is the center of an earthquake called?
An epicenter
What happened in Pompeii, Italy?
A volcano blew unexpectedly and the lava moved so fast that it covered an entire town
What is the difference between a rock and a mineral?
Minerals are 1 type of mineral/substance with a set formula and crystal formation. Rocks are a mix of minerals and aren't all identical.
