SashulF [63]2 years ago

Dynamo theory makes certain predictions. One is that a dynamo-induced magnetic field can exist only where a molten core exists within a fast-spinning planet. Small celestial bodies, such as Mars and the asteroids, long ago lost their heat, which shuts down the necessary convection near their cores. Venus is large enough to have retained its heat, but it spins very slowly, reducing the motion of its core and weakening the field. Mercury, which is too small to retain its primordial heat, does have a magnetic field as a result of its extreme inclination, which is allowed for in dynamo theory.

What type of rock is limestone? Describe how a limestone rock is likely to change over a long period of time.
Readme [11.4K]

Answer: Limestone is a sedimentary rock.

Explanation:

1. Limestone is a carbonate sedimentary rock made up of calcite(CaCO₃).This rock type forms calcareous shells and tests of organisms that was deposited in a sedimentary basin.

Limestone is used in building and construction works. It also finds application in chemical industries.

2. Over a long period of time, we would take a look at the rock "limestone" through the rock cycle.

Limestone being a sedimentary rock would be converted to marble, a metamorphic rock if subjected to metamorphic conditions over an extensive period of time. With series of metamorphic transformation, marble can grade to higher metamorphic facies of rocks as it combines with other minerals in the crust. The minerals would eventually change and as the changed rock approaches its melting temperature, melt would result.

From the other spectrum, limestone can be weathered if subjected extensively to denudation forces such as wind, water and glaciation. Water is more potent for the chemical weathering of limestone. Limestone would easily and readily dissolve in it over a long period of time.
