Continental Movement Flashcard

Front

What is the primary method used by GPS to measure tectonic plate movement?

Back

GPS measures tectonic plate movement by tracking the precise location changes of ground-based receivers over time.

Front

What geological process creates new oceanic crust at mid-ocean ridges?

Back

Sea Floor Spreading.

Front

How does SONAR function in mapping the ocean floor?

Back

SONAR maps the ocean floor by emitting sound waves and analyzing the returning echoes to determine depth and topography.

Back

Alfred Wegener.

Front

What is the significance of mid-ocean ridges in plate tectonics?

Back

Mid-ocean ridges are sites of sea floor spreading where new oceanic crust is formed.

Front

Define tectonic plates.

Back

Tectonic plates are large sections of the Earth's lithosphere that move and interact with one another.

Front

What is the role of subduction zones in plate tectonics?

Back

Subduction zones are areas where one tectonic plate is being forced under another, leading to recycling of crust and geological activity.

Explain the concept of continental drift.

Back

Continental drift is the theory that continents have moved over geological time and were once joined together in a supercontinent.

What is the relationship between earthquakes and tectonic plate movement?

Back

Earthquakes often occur at the boundaries of tectonic plates due to their movement and interaction.
