Answer: Incomplete
"Check all that apply. porosity, moisture, temperature, mineral, softness, or ease of dissolving"
<em>From the options, the three answers are </em><u><em>mineral composition,</em></u><em> </em><u><em>ease of dissolving</em></u><em> and p</em>
Explanation:
Weathering is the phenomenon in which surface of rocks are broken down and leaches or washed away.
The factors that affect the rock type and rate of weathering of said rock include:
- Composition: this translates to the <u>mineral composition </u>in the rock and how susceptible to chemical weathering reaction
- Surface area and porosity: Surface <u>porosity </u>determines how easily the rock can be leached by wind or rain.
- Climate: Mechanical weathering due to extreme climate change can cause freezing and thawing of the rocks, thereby enhancing disintegration of the rock. This is determined by the <u>ease of dissolving </u>of the rock.
Thermohaline circulation drives a global-scale system of currents called the “global conveyor belt.” The conveyor belt begins on the surface of the ocean near the pole in the North Atlantic. Here, the water is chilled by arctic temperatures.
1) One way is through radiographs. Scientists have studied the spectrum that distant nebulas give off and they have managed to identify molecules that can be found in there. Among them there is hydrogen and various nitrogen and carbon molecules; even alcohol has been found some of them. Another way is by sending probes to asteroids that check not only for simple organic molecules but also aminoacids and nucleotides. A third way was the Urey Miller experiment. There, some basic atoms that can be found in space (nitrogen, hydrogen and carbon) where put together with a spark in a flask. The mixture turned brown and produced complex organic molecules quite soon. This finding makes a case for complex organic molecules being produced in space and thus it is possible that they were transferred to Earth.
2) Geothermal vents are a source of hot water and raw nutrients such as sulphur. The main theory about the genesis of life around vents is that the cells started exploiting the pH or the thermal gradient near those vents and thus had a way to produce energy. The experimental set up for this is a chemical garden, an environment that simulates those alkaline and metallic conditions and yields hollow, plant-like structures. Also some metals in the vents are great catalysts for chemical reactions in organisms. Also fossilised microbes have been found beneath such vents.
Answer:
A
Explanation:
A velocity includes speed and kinetic energy is basically equal to "movement" energy. Speed is movement and more movement, more kinetic energy.
Answer:
there must be as equal number of atoms of each element on both sides of the equation
I would appreciate if my answer is chosen as a brainliest answer
