What are the two type of sound?
Eg. in an earthquake, they are called the primary and the secondary sound waves. grrrrrr
Is the transformer's iron core called the primary?
No. the primary winding is called the primary; the secondary winding is called the secondary. These are both wrapped around the iron core of the transformer. The core helps magnetically link the primary and secondary, which causes the transformation of voltage and current from primary to secondary.
How do seismic waves affect us?
Seismic waves affect us because they are what causes the motion from an earthquake that destroy buildings and such. The three types of seismic waves are surface waves primary waves also called P-waves and secondary waves also called S-waves.
What is the difference between primary secondary and tertiary consumers?
Some consumers are called "primary consumers" and others are called "secondary consumers" because the primary consumer is the first consumer and a secondary is the second consumer.
What was the most powerful earthquake?
Surface waves (of which there are two - the Love and Rayleigh wave) cause the majority of damage during an earthquake.
What is the surface above an earthquake called?
epicenter
What wave is called the secondary wave?
primary
Underground center of an earthquake?
Earthquakes occur underground and are felt on the surface. The center of an earthquake on the surface is called the epicenter, and the center of the earthquake underground, where it occurs, is called the hypocenter or focus.
What is the center of an earthquake?
It is called the focus, and the point on Earth's surface located directly above the earthquake focus is called the epicenter of the earthquake.
What is an earthquake's source called?
The source of an earthquake is called the hypocenter, the point on the surface directly above it is the epicenter.
how do scientists determine earthquake location and how do they use this information?
Scientists use devices called Seismographs to determine the epicenter of an earthquake. If 3 or more seismographs detect an earthquake, seismic wave activity can be measured and quantified and then cross-referenced with other data (the primary and secondary seismic waves) to determine the earthquake's location.
What is the origin of an earthquake under the surface of earth called?
This is known as the focus or hypocentre of an earthquake.
