Study Notes
Transform Boundaries
- Occur where tectonic plates slide past each other, leading to a horizontal motion.
- No addition or destruction of material occurs at these boundaries.
Tectonic Plates
- Composed of the Earth's crust; these masses shift and create surface changes.
Lithosphere
- The Earth's outermost rocky layer, consisting of both oceanic and continental crust.
Crust
- Divided into two main sections: Oceanic Crust and Continental Crust.
Oceanic Crust
- Thinner and denser type of crust, made primarily of liquid.
Continental Crust
- Thicker and less dense than oceanic crust, composed of solid material.
Asthenosphere
- A soft layer in the mantle that allows tectonic plates to move.
Mantle
- Located beneath the crust, includes portions of both the lithosphere and the asthenosphere.
Abrasion
- Refers to the buildup of energy that can be released suddenly, leading to large earthquakes.
Shear Force (Stress)
- A force that causes deformation through slippage along parallel planes, crucial for landslides and earthquakes.
Earthquakes and Tsunamis
- Natural disasters resulting from shear stress and abrasion at transform boundaries, impacting both the Earth and its inhabitants.
Fault
- A fracture in the lithosphere where blocks of rock (plates) move past each other.
Strike-Slip Fault
- A fault type involving two plates shifting sideways in opposite directions.
Reverse Fault
- Formed by two plates shifting towards each other at angles, leading to overlapping edges.
Normal Fault
- Occurs when overlapping plates move apart, causing a drop in elevation.
