Seismic Waves and the Earth | GCSE Physics Practice
Earthquakes produce waves that travel through the Earth, revealing its internal structure.
Which seismic wave can travel through the liquid outer core?
What is Seismic Waves and the Earth | Practice?
"Waves of energy that travel through the Earth's layers, often as a result of earthquakes."
Which of these is an example of a longitudinal wave?
If an object absorbs more radiation than it emits, its temperature will ____.
Arrange these EM waves in order of INCREASING energy: Radio, Visible, UV, Gamma.
The distance between the same point on two adjacent waves is called the ____.
Earth Structure
P-waves: Longitudinal, faster, travel through solids and liquids.
S-waves: Transverse, slower, ONLY travel through solids.
S-wave shadow zones prove the Earth has a liquid outer core.
P-wave refraction shows the density changes at boundaries.
Memory Trick: "P" for Primary (first to arrive) and Pressure (longitudinal). "S" for Secondary and Solid (only solids).

The fastest way to improve your grade is to practise exam-style questions, identify your gaps, and focus only on what you don't know.
