How long does it take the seismic waves to pass directly through the Earth?

Answers

Answer 1

Answer:

It ranges from 2 to 13 km/s depends upon composition.

Explanation:

The velocity of seismic waves are different throughout the earth because of different composition of the layers inside the earth. Velocity of seismic waves increases with depth and it is approximately 2 to 8 km/s in the Earth's crust whereas, 13 km/s in the deep mantle so it means the velocity of seismic waves is higher in the mantle as compared to earth's crust due to different composition of layers between the mantle and earth crust.

Give the reason why the international date line is significant​

Answers

Answer:

The International date line serves as the line of demarcation between two consecutive calendar dates the International date line shown here as a yellow line define'd the boundary calendar dates when you cross the date line

The International date line is important because it helps tell what time it is across different time zones.

The International date line:

Divides the world into two such that one side is ahead of the other temporally. Located on the opposite side of the Prime Meridian

The Earth rotates around the sun which means that some areas will see the sun before others and therefore would be ahead during the day.

There is therefore a need to know the time it is in an area based on when the sun hits that area. This is the purpose of the international date line - by dividing the Earth in two, we are able to know which point to start counting the relative hours from.

In conclusion, the International date line allows for humans to tell the time according to what timezone they are in.

Answers

Answer:

Explanation:

A planet can be defined as a large celestial body having sufficient mass to allow for self-gravity and make it assume a nearly circular shape (hydrostatic equilibrium), revolves in an orbit around the Sun in the solar system and has a cleared neighborhood.

Basically, the planets are divided into two (2) main categories and these includes;

I. Outer planets: these planets are beyond the asteroid belt and comprises of jupiter, saturn, uranus and neptune, from left to right of the solar system.

II. Inner planets: these planets are the closest to the sun and comprises of mercury, venus, earth and mars.

The outer planets are made mostly of gas (hydrogen and helium) which makes them less dense than the solid inner planets. These gases are generally known to be less dense in terms of physical properties.

Current market terms are 8 percent interest for 25 years for a fully amortizing loan. The borrower, Rich, has requested a $100,000 loan. The lender believes that extra credit analysis and careful loan control will have to be exercised because Rich has never borrowed such a large sum before. In addition, the lender expects that market rates will move upward very soon, perhaps even before the loan is closed. To be on the safe side, the lender decides to extend Rich a fixed rate, constant payment mortgage (CPM) loan commitment of $95,000 at 9 percent interest for 25 years.
