Answer:

Will u give me brainliest

white

In its pure form, it is silvery white, and relatively soft. It burns in air with a brilliant white light, and for this reason is often used in flares and fireworks. Magnesium is used in disposable flash bulbs to generate light for photography, but this use has been largely supplanted by other sources of illumination

A. They are the most destructive earthquake waves.

D. They can move in a rolling pattern through rock, like an ocean  wave.

Explanation:

Surface waves are seismic waves that cause the most destruction during an earthquake.

Rayleigh waves are known to cause rolling pattern of rocks just like an ocean waves.

  • Seismic waves are elastic waves that notably transmits energy.
  • They usually accompany earthquakes.
  • There are two broad categories of these waves.
  • Surface and body waves.
  • Seismic surface waves are low frequency and long wavelength waves.
  • They travel very close to the surface.
  • They are made up of Love and Rayleigh waves.
  • Love waves travels laterally in a horizontal fashion.
  • Rayleigh waves rolls like ocean waves in the ground.
  • The bulk of the destruction caused during an earthquakes is due to these waves.
  • They are the last waves to arrive a seismic station

Why is the use of inquiry process a practical way to approach science?
just olya [345]

Answer:

Explanation:

Inquiry making is one of the methodical approaches to scientific investigation. Inquiry basically deals with asking question and querying a certain procedure or observation. In almost all the phases of a scientific investigation, the scientist will not cease to keep on asking questions that are connected to the observations and how this can help to further broaden the scope of the experiment. In fact, every investigation in science is an inquiry into a phenomenon and this generates series of questions that need to be satisfied.
