Vocabulary
Hot liquid rock under the Earth's surface.
What is Magma?
When sediment is buried pressed together.
What is compaction?
Igneous rock is formed when magma ______.
What is cools and hardens.
They type of rock formed from heat and pressure
what is metamorphic rock?
The energy that melts rock under the Earth's surface comes from this source.
What is Earth's Interior?
During a convergent boundary, this is when one plate goes under the other, into the mantle.
What is subduction?
Geologists have evidence of an igneous rock formation under Earth’s outer layer. Is it possible that material from this rock formation could ever form sedimentary rock on Earth’s surface?
What is Yes, if igneous rock is moved to Earth’s surface and exposed to energy from the sun, it could weather into small rock pieces that could form sedimentary rock.
Giovanni and his family go on a trip and they drive over a mountain range. Giovanni wonders how the rock they see as they drive over the mountain range might be different when they drive back home next week. What would you tell Giovanni about how the rock will change?
What is the rock is not likely to change very much. Most rock transformation processes happen very slowly.
The type of rocks that can be weathered and transformed into sediment.
The energy for weathering comes from this source.
What is the sun?
The movement of sediment from one place to another often caused by wind or flowing water.
What is erosion?
When sediment is glued together.
What is cementation?
Igneous rock is formed on the surface because of this geologic event.
What is a volcano?
On the island of Hawaii, Keanu notices that the sand on the beach is black, the same color as the rock formations on the island. Keanu realizes the sand used to be part of the rock formations. How did material from the rock formations turn into sand?
What is wind and rain interacted with the rock, breaking it into small pieces.
Hank passes by a building every day on his way to school. He notices that the rock used to build the walls of the building is a different type than the rock used to build the steps. How could energy have played a role in the different rock types forming?
What is energy from different sources leads to different types of rock. Energy inside Earth melts rock into liquid rock, but energy from the sun causes rock to weather into small pieces of rock.
The process of rock breaking down into smaller pieces.
What is weathering?
The type of rock formed after compaction and cementation.
What is Sedimentary Rock?
There are __________ types of rocks. (a number)
What is three?
the type rock formed from the energy from the sun
What is sedimentary rock?
Energy from ______________ forms sediment and energy from ____________ forms magma.
What is the Sun and Earth's Interior?
The process of rock being pushed up by plate motion.
What is uplift?
A geology student describes a rock sample she is studying in class. The rock sample is igneous rock, but the student wonders if the material that it formed from was part of a sedimentary rock formation millions of years ago. Could this be correct? Could the material for igneous rock come from sedimentary rock?
What is Yes, if sedimentary rock is moved below Earth’s outer layer and exposed to energy from Earth’s interior, it can melt into liquid rock and form igneous rock.
A rock formation made of metamorphic rock was once deep underground. This process brought the rock formation to the surface.
What is uplift?
How could materials of an igneous rock come from a sedimentary rock formed millions of years earlier?
What is when a sedimentary rock moves below Earth's surface is melted, then cooled?
How can sedimentary or igneous rock become metamorphic rock?
What is subduction or heat and pressure?
