Plate Tectonics Concepts
Plate tectonics is a scientific theory that describes the large-scale movement of Earth’s lithosphere. The lithosphere is the rigid outermost layer of Earth, which is composed of the crust and the uppermost mantle.
The lithosphere is divided into a number of tectonic plates, which are constantly moving relative to each other. The movement of the plates is driven by convection currents in the Earth’s mantle.
There are three main types of plate boundaries: convergent boundaries, divergent boundaries, and transform boundaries.
Convergent Boundaries
- Convergent boundaries are where two plates collide with each other.
- When two oceanic plates collide, one plate is usually subducted beneath the other, forming a volcanic arc.
- When an oceanic plate and a continental plate collide, the oceanic plate is usually subducted beneath the continental plate, forming a mountain range.
Divergent Boundaries, Plate tectonics lab report 3 answer key
- Divergent boundaries are where two plates move away from each other.
- When two oceanic plates diverge, new oceanic crust is formed in the gap between the plates.
- When an oceanic plate and a continental plate diverge, the continental plate is stretched and thinned, forming a rift valley.
Transform Boundaries
- Transform boundaries are where two plates slide past each other.
- Transform boundaries are often associated with earthquakes.
FAQ: Plate Tectonics Lab Report 3 Answer Key
What is the significance of plate tectonics?
Plate tectonics plays a crucial role in shaping Earth’s surface, driving continental drift, mountain formation, and the distribution of natural resources.
How do different types of plate boundaries affect Earth’s crust?
Plate boundaries are zones where tectonic plates interact, leading to diverse processes such as subduction, collision, and spreading, which shape the Earth’s crust.
