Let us look at the what, why and how of studying extreme places like the deep earth and the deep space. Scientists need to figure out as to 'what' they want to look at such places, be it a new exotic creature or bio-genesis (birth of life). Unless there are several testable hypothesis constructed, such a study cannot begin. The 'why' aspect deals with the purpose of such research and expeditions. Is it of any use to the humans, or will it improve our current understanding of a phenomenon? The 'how' aspect deals with the technology and the economic assistance that can help in undertaking such a research. All these are the challenges that needed to be thoroughly considered to make such a research or expedition possible.
Answer: Increase in compactness of the material.
Explanation:
Evaporites are the sedimentary rocks that are formed by the sediments and brines of the materials being degraded or withered from the parent and pre-existing rocks. The water is also lost from the withered material due to evaporation. The borax and gypsum also lose water to become evaporites and the increase in compactness due to loss of water molecules and increase in intramolecular forces between solid substances in the rock helps in sedimentation of the rock.
Actually, heavier objects fall faster. The difference is infinitesimal, but there is a tiny difference because more mass causes objects to fall faster (e.g. objects fall faster on earth than on the moon). On earth, the different rate of fall between heavier and lighter objects is negligible (because objects are tiny compared to the earth's mass), so objects of different weights fall at virtually the same rate. But not at exactly the same rate. Objects of different weights must accelerate at different rates because accel.
Every organism is unique, even though the nucleotides making up DNA are all the same, because the structure is different in every organism. In other words, it's just the order in which nucleotides are placed that differs each organism from one another.
