10 Questions
In which type of seismic waves is the displacement of the particle practically horizontal?
Love Waves
How are earthquakes classified based on various factors?
Depth of focus, cause of origin, intensity, and magnitude
What is the direction of displacement of particles in Love Waves?
Horizontal
What are some criteria used to classify earthquakes?
Depth, cause, intensity, and magnitude
Which type of seismic waves propagate with practically horizontal displacement?
Love Waves
Marine water erodes rocks at the shore and elsewhere in a manner different from stream water hydraulic action.
True
The rate of river erosion is typically slower than the erosion caused by marine water.
False
Hydraulic action plays a minimal role in the erosion caused by marine water.
False
The erosion caused by marine water is unrelated to the erosional processes of stream water.
False
Marine water erodes rocks solely through chemical weathering processes.
False
Study Notes
- Physical geology studies the origin, development, and fate of Earth's surface features and internal structure.
- Stream water can flow in two types of flow: laminar or turbulent, depending on the section of its channel.
- Gullies are early stages of valleys, which deepen and widen with erosion to accommodate larger water volumes.
- Streams widen valleys by cutting down channels, removing loose soil and rocks from banks.
- Earthquakes are classified based on depth of focus, cause of origin, intensity, and magnitude, such as Love Waves with horizontal particle displacement.
- River erosion methods include hydraulic action for material removal and cavitation as a rare type of hydraulic action.
- Marine water erodes rocks similarly to stream water through hydraulic action at the shore and other contact areas.
Learn about the formation of gullies through erosion, as they develop from incipient valleys to accommodate larger volumes of water causing further erosion.
