Limestone deposits are often evidence of ancient tropical seas.
true or false

The correct answer is True

Explanation:

Limestone is a type of rocky material that is mainly formed of fragments of ancient marine organism especially organisms such as coral or mollusks in tropical seas as these organisms are made from calcium carbonate that dissolves over time and forms piles of limestone process that takes many years. Because of this, it is true limestone deposits are often evidence of ancient tropical seas because limestone is formed as the result of organisms that live mainly in tropical seas, rather than in other types of seas, and also this process takes many years which means seas that are now limestone are mainly ancient or existed just miles of years ago.

an adaptation is a change or process by which an organism takes to be better suited for its environment. for example; migration is a behavioral adaptation, this is needed because birds are not built to last extremely cold climates. there are different adaptations because there are different species needing to adjust to different things, bears don't migrate; they hibernate.

phaneritic textures in which phaner means visible so phaneritic textures are standard of impertinent volcanic rocks. these rocks crystallized gradually under the surface of earth. when the magma cools deliberately then the ores have chance to develop and produce long crystals.
