Explanation:
When the magnet is placed on the glass, it is attracted to the iron filings. The pattern of the iron filings shows that the lines of force that make up the magnetic field of the magnet. Also, The lines of force of north and south poles attract each other whereas those of two north poles fend off each other.

Answer:
The answer is B. composition
Explanation:
- The speed of a seismic wave is governed by three interrelated factors, viz. the composition of the rock, pressure, and temperature.
- Seismic waves travel at different speeds in different mediums.
- This property of the seismic waves tends it to change the speed where the concentration of minerals in the rocks varies.
- Other than that, the increasing temperature beneath the Earth's surface decreases the speed of the seismic waves, and the speed increases with increasing pressure as the waves go penetrating deep down into the Earth's interiors.
