Vocab Tems

Amplitude

In both sound and electromagnet waves - this is a key factor in determining the energy of a wave; greater the height - means more energy

P waves

fast, weak, travel through solids, liquids, and gases

Frequency

refers to the number of occurrences of a repeating event per unit of time. In physics, it is often measured in hertz (Hz)

Longitudinal

P waves

sound waves in air

compression waves in a slinky

Transverse

Light Waves: electromagnetic waves that do not require a medium

Seismic S-waves: secondary waves that move through the Earth during an earthquake

epicenter

the point on the Earth's surface directly above the focus of an earthquake. It is where the seismic waves first reach the surface, often resulting in most intense shaking the location of the epicenter is typically determined using data from seismographs

Focus

the actual location within the Earth where an earthquake originates, also known as the hypocenter.

Seismologist

a scientist who studies earthquakes and the propagation of seismic waves through the Earth. They analyze data to understand seismic events and assess risk.

Seismo

a prefix related to earthquakes or seismic activity.

Seismometer

an instrument used to detect and record the vibrations caused by seismic waves as they travel through the Earth. It is valuable data for understanding the Earth's internal structure and behavior.

Seismogram

is a record produced by a seismograph which measures the motion of the ground during an earthquake or other seismic events it displays the amp platoon and frequency of the seismic waves allowing scientists to analyze the characteristics of the earthquake, such as it's magnitude and location Seismograms are crucial for understanding seismic activity and improving earthquake preparedness.

earthquake

shaking and trembling the results from the movement of rock beneath earth's surface

seismic waves

carries the energy of an earthquake away from the focus, through Earth's interior and across the surface

S waves

strong, slow, and can travel through solids only
