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.

Answer: Map scale can be defined as the relationship that can be drawn in between the length of the map and the length of the ground.
Explanation:
The unit of the length on the map and the corresponding length of the ground is the map scale. The type of map scales:
Large Scale 1:25,000 or more
Medium Scale 1:1,000,000 to 1:25,000
Small Scale 1:1,000,000 or less
Small scale and medium scale can demonstrate large area for example a country or state whereas the large scale can demonstrate a small area like a city or region of city.

Answer:
Scholars knew that the Egyptians believed in afterlife, because, first, after the discovery of the Rosetta stone, they were able to read many ancient scripts that mentioned procedures to ensure that one goes to the afterlife.
Explanation:
The correct answer is - Magma generated from a hot spot burned through the overlying plate to create volcanoes.
The Hawaiian Islands are all formed as a result of volcanic activity of a hot spot. The hot spot is stationary, but the islands are in the shape of a chain, not all in the same place. Also, the rocks on the islands that do not have active volcanoes are older, than the ones that do have volcanic activity. This suggests that the Pacific plate is moving. According the direction in which the islands are arranged, the Pacific plate seems to move toward northwest. As it moves, it moves over the hot spot. Since the hot spot is stationary, as the Pacific plate moves, eventually the volcanic activity will stop on the island that has moved further away from the hot spot. The magma from the hot spot will penetrate through the crust that came to be over it. That will result in new volcanic island emerging from the sea over the hot spot. The process goes on for millions of years, and it can result in hundreds of islands of volcanic origin.
