ACTIVITY 2: Describe Me? Describe Me Not? Write VOLCANO if the statement is TRUE. Write MOUNTAIN if the statement is FALSE 1. Most earthquakes occur in the boundaries of lithospheric plates. 2. Tsunamis are caused by underwater earthquakes. 3. Active volcanoes will form anywhere in the lithosphere. -4. Formation of mountain ranges and volcanoes is not related to Plate Tectonics. 5. Tectonic plates movement caused the occurrence of earthquakes on land and underwater.
Most earthquakes occur at the boundaries where the plates meet. In fact, the locations of earthquakes and the kinds of ruptures they produce help scientists define the plate boundaries. There are three types of plate boundaries: spreading zones, transform faults, and subduction zones
What Causes a Tsunami? These awe-inspiring waves are typically caused by large, undersea earthquakes at tectonic plate boundaries. When the ocean floor at a plate boundary rises or falls suddenly, it displaces the water above it and launches the rolling waves that will become a tsunami
Tectonic activity is responsible for some of Earth's most dramatic geologic events: earthquakes, volcanoes, orogeny (mountain-building), and deep ocean trenches can all be formed by tectonic activity in the lithosphere.
Movements of tectonic plates create volcanoes along the plate boundaries, which erupt and form mountains. A volcanic arc system is a series of volcanoes that form near a subduction zone where the crust of a sinking oceanic plate melts.
Earthquakes occur along fault lines, cracks in Earth's crust where tectonic plates meet. They occur where plates are subducting, spreading, slipping, or colliding. As the plates grind together, they get stuck and pressure builds up. Finally, the pressure between the plates is so great that they break loose.
