Answer:

Heat from the mantle forms convection currents causing the tectonic plates to diverge and form ocean basins.

Explanation:

Ocean basins form as a result of convection in the mantle along divergent margins.

  • At a divergent margin, new crusts are being formed.
  • It is said to be a constructive margin because new materials reaches through to the earth surface from there.
  • The mantle convection pushes materials up  and down away from heating centers and to cold regions and back and forth.
  • This leads to the creation of cells which moves the overlying plate.
  • The mantle materials are then able to reach the surface to form new ocean basin.

The mathematical system in Mesopotamia was based on the number 7. O True False
Anuta_ua [19.1K]

It is false that the mathematical system in Mesopotamia was based on the number 7. O.

<u>Explanation:</u>

The mathematical system is Mesopotamia was based on the number 60 at it's base and not on 7. This numeral system is known as sexagesimal which had 60 at it's base.

This originated in the 3rd millennium BC and passed on to the ancient Babylonians and it is still used for measuring angles, times, geographic co ordinates. Since the statement that the mathematical system in Mesopotamia was based on number 7 is incorrect.

slamgirl [31]

Answer:

Ellen gave 24 inches of her ribbon to the friend.

Explanation:

The total length of ribbon Ellen has = 20 feet

Used to make pillows = 12 feet

Remaining ribbon = 20-12 = 8 feet

Given to her friend = 1/4

1/4 of 8 = 1/4 × 8 = 2 feet

so she gave 2 feet of ribbon to her friend.

  • As there are 12 inches in 1 foot.

so

2 feet in inches = 24 inches

Therefore, Ellen gave 24 inches of her ribbon to the friend.
