All Flashcards
What geological features are associated with oceanic-oceanic convergent boundaries?
Island arcs, oceanic trenches, and volcanoes.
What geological features are associated with oceanic-continental convergent boundaries?
Mountains and volcanoes.
What is the primary feature of a transform boundary?
Earthquakes.
How does plate tectonics contribute to the formation of volcanoes?
Subduction at convergent boundaries and magma rising at divergent boundaries.
How does plate tectonics contribute to the formation of earthquakes?
Friction and energy release at transform boundaries.
Why is the Ring of Fire significant?
It's a hotbed of volcanic and seismic activity due to the many plate boundaries.
What drives the movement of tectonic plates?
Convection currents in the Earth's mantle.
What is the role of density in subduction?
The denser plate subducts beneath the less dense plate.
How does seafloor spreading support the theory of plate tectonics?
It provides evidence of new crust formation at divergent boundaries, demonstrating plate movement.
What is the relationship between plate tectonics and mountain building?
Collision at convergent boundaries can cause folding and uplift, forming mountain ranges.
What is the effect of plate convergence?
Mountains, volcanoes, subduction zones, and oceanic trenches.
What is the effect of plate divergence?
Rift valleys, seafloor spreading, and volcanic activity.
What is the effect of plates sliding past each other?
Earthquakes.
What causes the Ring of Fire's activity?
Subduction zones around the Pacific Ocean cause frequent volcanic eruptions and earthquakes.
What is the effect of subduction on the mantle?
Introduces water, lowering the melting point and creating magma.
What is the effect of seafloor spreading on the ocean?
Creates new oceanic crust and widens the ocean basin.
What is the effect of friction at transform boundaries?
Builds up stress, which is released as earthquakes.
How does plate tectonics affect climate?
Volcanic eruptions release gases that can temporarily cool the planet, and mountain ranges influence weather patterns.
What is the effect of tectonic plate movement on the distribution of species?
Separation of landmasses leads to the evolution of unique species on different continents.
What is the effect of understanding plate tectonics on disaster preparedness?
Allows for better prediction and mitigation of earthquakes and volcanic eruptions.
What is the effect of transform boundaries?
Earthquakes due to friction and sudden release of energy.
What is the effect of convergent boundaries?
Formation of mountains, volcanoes, and trenches.
What is the effect of divergent boundaries?
Seafloor spreading, rift valleys, and volcanic activity.
What is the cause of the Ring of Fire's intense geological activity?
Numerous convergent plate boundaries and subduction zones.
What is a consequence of building structures on or near fault lines?
Increased risk of damage or collapse during earthquakes.
What is the effect of increased volcanic activity due to plate tectonics on the atmosphere?
Release of gases and ash, potentially affecting climate and air quality.
What is the cause of tsunamis in coastal regions?
Undersea earthquakes caused by tectonic plate movement.
What is the effect of the collision of the Indian and Eurasian plates?
Formation of the Himalayan mountain range.
What is the cause of the formation of the Mariana Trench?
Subduction of the Pacific Plate under the Mariana Plate at a convergent boundary.
What is the effect of plate tectonics on the distribution of natural resources?
Concentration of minerals and fossil fuels in specific geological formations.
