Out of the choices listed, limestone is the most abundant chemical sedimentary rock. These are formed by the combination of water components to create a new compound, with limestone usually created from calcium carbonate shells in certain environments. therefore, option c is correct.
The most abundant chemical sedimentary rock among the options provided is limestone. Sedimentary rocks are formed by the deposition and subsequent cementation of mineral or organic particles on the floor of oceans or other bodies of water at the Earth's surfaces. Chemical sedimentary rocks, like limestone, are created when water components combine to form a new compound. For example, limestone is usually formed in clear, warm, marine environments from the calcium carbonate shells of organisms.

Answer:
Near source of raw material.
Explanation:
The Southern Hemisphere receives more direct rays from the Sun.
The Northern and Southern Hemispheres get the same amount of energy from the Sun.
The Northern Hemisphere receives more daylight hours than the Southern Hemisphere.
When the Northern Hemisphereexperiences spring and the Southern Hemisphereexperiences fall then The Northern and Southern Hemispheres get the same amount of energy from the Sun.
When the month of March and September arises, the sun energy is seen the same in both the North and South hemispheres. The is achieved due to no end of the Earth's axis being tilted in the direction of the sun.
In the season of winter, sunlight is received more towards the South hemisphere while in summers the North hemisphere gets more of the sunlight.

Explanation:
The answer is The unsorted sand and rock is the least porous. The porousness of a solid material is dependent on the size of holes within it. This can be tested by how quickly, the material can pass a liquid through it. The bigger the holes, the higher the porousness, In this case, the unsorted sand and rock have the smallest holes between its particles.
Large pebbles and boulders materials is the least porous. Correct option is D.
Large pebbles and boulders are the least porous among the given options. Porosity refers to the percentage of void space or openings (pores) within a material that can hold fluids like water, air, or other substances. It is a measure of how much empty space exists within the material.
In the given options:
a. loosely packed gravel: Gravel generally has larger particles and may have relatively higher porosity compared to other options.
b. sorted sand and rock: Sorted sand and rock may have some porosity depending on the grain size and how well-packed the particles are, but it is likely to be less porous than loosely packed gravel.
c. unsorted sand and rock: Unsorted sand and rock may have varying porosity depending on the mixture, but it is likely to be less porous than loosely packed gravel.
d. large pebbles and boulders: Large pebbles and boulders have minimal pore space compared to the other options. The particles are relatively large and leave less room for open space between them, resulting in lower porosity.
So, the material with the least porosity among the given options is "d. large pebbles and boulders."
