Boundary & Crust
convergent boundary
What is when two tectonic plates collide?
Volcanos are formed.
what is An oceanic crust goes under a continental crust (continental is thicker) it forms a subduction zone, and the land gets pushed up. Then the magma pushes up when it’s ready and makes an eruption?
Plate tectonics
What is the theory that describes how certain parts of Earth that are divided(Plates) interact with each other?
heat moves from one object to another object through direct touch
What is Conduction
Superposition
What is the theory that in layers of rock, the oldest rock is the bottom layer and the youngest layer is the top layer?
The oceanic crust goes under a continental crust.
What is the Subduction Zone?
two continental plates collide and the land pushes up
What is Mountain Ranges?
The theory of Plate tectonics is made by
Who is Alferd Wegner?
Something that transfers heat through waves.
What is Radiation?
fossil evidence
What is the preserved traces/remains of animals and plants?
Transform boundaries
What is when two plates slide past each other?
when two tectonic plates pull away from each other
What is Ocean Basin formation/Seafloor spreading.
Our Earth was in a super continent.
What is Pangea?
he movement of particles through a substance, transporting their heat energy from hotter areas to cooler areas.
what is Convection?
Why are the fossils of the same organisms in different continents/far away
What is the theory of continental drift. There was once a supercontinent called Pangea, but Pangea slowly drifted apart over time, and separated species. This created the 7 continents we now know today?
Divergent Boundaries
What is When two tectonic plates separate from each other?
Tectonic plates are always moving. But when they get stuck and can’t move anymore, and then suddenly move they form.
what is Earthquakes?
The Nazca plate is located
What is near South America?
the energy contained within a system that is responsible for its temperature
what is Thermal energy?
here is a rock with 3 layers. The bottom layer consists of fern fossils and mammoth bones. The 2nd layer is made of metamorphic rock. The top layer is made of crystalline limestone. Which layer was formed last?
What is the crystalline limestone?
The Earth’s outer layer is hard, and rocky
What is Lithosphere?
This is most common at transform boundaries. Tectonic plates are always moving. But when they get stuck and can’t move anymore, and then suddenly move, it forms
What is Earthquakes?
San Andreas Fault is the border between 2 plates
What is the Pacific Plate and the North American Plate?
the energy transfer if an ice cube melts from the sun
what is Radiation?
Some fern fossils and remains are found in South America. The same traces of fern were also found in North America. What explains this cause?
What is The continents drifted apart over time.
