Answer: b. comparing the arrival times of the P-and S-waves.

Explanation: The epicenter of earthquakes is the location where the earthquake starts in the earth crust. To calculate the distance to the epicenter of an earthquake, you need to compare the arrival times of the P waves and the S waves. On a seismograph, a line is equivalent to 1 minute but it depends on the scale used.

Determine the magnitude of the earthquake by plotting the distance and amplitude on a chart and joining the two points.

Triangulation is then used to locate the epicenter. Three circles with a radius of the magnitude are drawn around the affected parts. The epicenter is the point where these circles meet.

Mariulka [41]

Answer:

The wall acts as a dissipator for the energy of the ocean waves.

That is why on some coasts to reduce the force with which the waves collide on the shore, breakwaters are made to stop said maritime energy.

Explanation:

That is why this wall, if it is well built, acts as a barrier and stops the waves dissipating it with less energy on the maritime coast.

Anit [1.1K]

Answer:

The star is a member of an eclipsing binary star system

Explanation:

  • A careful explanation about the measurement reveals that the star maintains a steady and apparent shape of brightness and at most of the time remains brighter.
  • With and usual intervals of about the 73 hours and then the star becomes contestant dimmer for about every toe hours and is due to the fact that the star is a member of the eclipsing system.

Diano4ka-milaya [45]

Answer:

Clear Cutting

Pro: Financial Reasons. Clearcutting advocates argue that the method is the most efficient for both harvesting and replanting trees.

Pro: Increased Water Flow.

Con: Effects on Plant and Wildlife.

Con: Loss of Recreation Land.

Pro: Increased Farmland.

Selective Cutting

Pro: Supports more wildlife by keeping their ecosystems intact

Pro: They build up tolerance and resistance to disease and pests

Pro: Carbon dioxide that is stored by the trees will regenerate (regrow)

faster

Pro: Helps the forest grow back faster

Con: Expensive and time-consuming

Con: Some species will not regenerate (regrow) as fast

Con: More exposure to weather damage such as ice, storms, and fires

Con: Lots of stumps and other tree debris left behind

These are some things I could come up with while learning some info about this.
