When the Earth's continental crust and ocean crust formed, they were different densities. Why did they differ in density and how did this affect their formation?

A.) The continental crust was thicker and less dense. It rose above sea level, separating land from water.

B.) The continental crust was thicker and more dense. It sunk below sea level, separating land from water.

C.) The continental crust was thinner and less dense. It rose above sea level, separating land from water.

D.) The continental crust was thinner and more dense. It sunk below sea level, separating land from water.


I think it’s B, but I’m not completely sure. Help please!

Answers

Answer 1

Answer: A.) The continental crust was thicker and less dense. It rose above sea level, separating land from water.

Explanation:

The Ocean crust is made out of rocks like basalt with a thickness of about four miles. The Continental crust on the other hand is made out of granite and other similar minerals and is between six and 47 miles in thickness which makes it thicker than the Oceanic crust.

With basalt being more dense than granite, the Oceanic crust sank and the Continental crust rose thereby separating land from water.

what a Lunar Phase ?

Answers

Answer:

It’s something like The lunar phase or Moon phase is the shape of the Moon's directly sunlit portion as viewed from Earth. The lunar phases gradually change over a synodic month as the Moon's orbital positions around Earth and Earth around the Sun shift

Answer with Explanation:

A lunar phase is also known as a "moon phase." This refers to how we see the Moon in different shapes as it is reflected back to Earth. Such reflection depends on the portion of the Moon that is illuminated by the sun. This explains why the amount of moon that we view from Earth changes over time.

It consists of 8 phases: New Moon, Waxing Crescent, First Quarter, Waxing Gibbous, Full Moon, Waning Gibbous, Third Quarter and Waning Crescent.

Answers

Answer: cellular membrane: The cell membrane, also called the plasma membrane, is found in all cells and separates the interior of the cell from the outside environment. The cell membrane consists of a lipid bilayer that is semipermeable. The cell membrane regulates the transport of materials entering and exiting the cell.

Explanation:

passive transport Passive transport is a type of membrane transport that does not require energy to move substances across cell membranes. Instead of using cellular energy, like active transport, passive transport relies on the second law of thermodynamics to drive the movement of substances across cell membranes.
