Flashcards

What type of rock is best for containing nuclear waste?

Granite is the most suitable rock for storing nuclear waste because it is very dense and impermeable, preventing leaks.

Where do earthquakes and volcanoes occur?

Earthquakes and volcanoes typically occur at plate boundaries, specifically where two plates interact.

What causes an aquifer to form?

Aquifers form when groundwater flows through spaces between soil grains, usually sand or gravel, due to gravity.

What is a divergent plate boundary?

A divergent plate boundary occurs when two tectonic plates move apart, creating new lithosphere.

What is the theory of plate tectonics?

Plate tectonics is the theory that explains the Earth's lithosphere is divided into large plates that move and interact, causing earthquakes, volcanoes, and mountain formation.

Study Notes

Rock Properties for Nuclear Waste Containment

  • Granite is a suitable rock type for containing nuclear waste due to its durability and ability to prevent leaks.

Earthquake Mitigation Strategies

  • Strengthening building codes and installing seismometers can reduce earthquake damage.
  • Evacuating mountainous regions can help save lives during earthquakes or landslides.

Landslides and Water Flow

  • Water flows through soil due to gravity, filling spaces between soil grains.
  • Aquifers are often found between layers of gravel or sand.
  • Sandstone is a suitable rock for aquifers.

Plate Tectonics and Geological Phenomena

  • Earthquakes are a primary phenomenon at transform plate boundaries.
  • New lithosphere forms mainly at divergent plate boundaries.
  • The Earth's crust is composed of rock.
  • Temperature differences are needed for convection currents to occur.
  • Divergent boundaries occur when plates move apart.
  • Convergent boundaries occur when plates collide.
  • Transform boundaries occur when plates slide past each other.
  • Continental drift describes the movement of continents from a unified landmass (Pangaea).
  • Plate tectonics theory suggests that plates are mobile, supported by the fitting of continents like puzzle pieces.
