Yes, Venus is<span> sometimes </span>called Earth's twin<span> because </span>Venus<span> and </span>Earth<span> are almost the same size, have about the same mass (they weigh about the same), and have a very similar composition (are made of the same material). They are also neighboring planets. However, </span>Venus<span> and </span>Earth<span> are also very different.

Biochemical limestone is when the calcium carbonate is locked into the fossil shells and skeletons of marine organisms.
But chemical limestone is when the calcium carbonate is in the form of calcite mineral crystals.
Hope it helps!
Answer: Continental slope
The continental slope is said to be the steepest part of the continental margin, where there is a sudden decrease in slope or it suddenly descends down to the ocean floor and the sea floor begins to level out towards the abyssal plain. Moreover, this portion of the sea floor also marks the end of the continental margin called the continental rise.
From the cornea, the light passes through the pupil. The iris, or the colored part of your eye, controls the amount of light passing through. From there, it then hits the lens. This is the clear structure inside the eye that focuses light rays onto the retina.
Answer:
The mean center of population is the place where an imaginary, flat, weightless, and rigid map of the United States would balance perfectly if all residents were of equal weight. Historically, the movement of the center of population has reflected the expansion of the country, the settling of the frontier, waves of immigration and migration west and south. Since 1790, the center of population has moved steadily westward, angling to the southwest in recent decades.

NOTE: The Proclamation Line of 1763 limited British settlement to areas east of the Appalachian Mountains. Alaska and Hawaii were not included in the calculation of the mean center of population until 1950. Puerto Rico was not included in any decade.
