displays a warning message
What is the point inside the Earth where the energy is released during an earthquake called?
The epicenter (کانون زمین لرزه).
The crust (پوسته زمین).
The mantle (گوشته زمین).
The surface (سطح زمین).
What are the waves called that travel from the point of energy release to the surface during an earthquake?
Seismic waves (امواج لرزهای).
Tidal waves (امواج جزر و مدی).
Sound waves (امواج صوتی).
Light waves (امواج نوری).
Seismic waves can travel through different types of rocks inside the Earth and complete their real journey because:
they can pass through solids, liquids, and gases inside the Earth.
they only move through air inside the Earth.
they stop when they hit a new type of rock.
they are reflected back to the surface immediately.
When you tap one end of a table and your classmate feels the vibrations on the other side, and you repeat this with wooden and plastic tables, what do you observe?

Vibrations travel better through the plastic table than the wooden table.
Vibrations cannot be felt in either table.
Vibrations are equally strong in both tables.
