Rock Cycle
This type of rock forms when liquid rock cools and becomes solid.
What is igneous rock?
This energy source drives many processes that happen at Earth’s surface
What is the Sun?
Earth’s rocky outer layer is broken into large moving pieces called these.
What are tectonic plates?
This is the thin, outermost layer of Earth where we live.
What is the crust?
Which comes first when igneous rock eventually becomes sedimentary rock: melting or weathering?
What is weathering?
This type of rock can form when small pieces of rock are compacted and cemented together.
What is sedimentary rock?
This energy source drives processes deep inside Earth.
What is energy from Earth’s interior/mantle?
Plates can move toward each other, away from each other, or ________.
What is slide past each other?
This thick layer is located directly below Earth’s crust.
What is the mantle?
The name of the ancient supercontinent when most of Earth's landmasses joined together.
What is Pangaea?
Two rocks can be different types because they formed through different ________
What are processes?
This process must occur for solid rock to become liquid rock.
What is melting?
At this type of boundary, two plates move away from each other.
What is a divergent boundary?
This is the innermost layer of Earth.
What is the core?
A rock turns into liquid rock and then becomes solid. What two rock-cycle processes occurred?
What are melting and cooling?
When sedimentary rock melts, it becomes this material?
What is magma?
This process breaks rock into smaller pieces.
What is weathering?
At this type of boundary, two plates move toward each other.
What is a convergent boundary?
Put the layers in order from the outside of Earth to the inside
What is crust → mantle → core?
Rock is broken into smaller pieces that can be moved to another location. Name the rock-cycle processes involved.
What are weathering and erosion?
Name a possible sequence (steps) that could change igneous rock into sedimentary rock.
What is weathering/erosion → sediments → compaction and cementation
The three main types of rocks that are created because of constant movement through the cycle.
What are igneous, sedimentary and metamorphic rock?
This occurs when one tectonic plate moves underneath another plate.
What is subduction?
Tectonic plates are pieces of Earth’s outer layer that move slowly over material below them. Which two Earth layers are involved?
What are the crust and mantle?
Scientists find the same fossil on continents now separated by an ocean. What is the best explanation?
What is the continents were once connected and later moved apart?
