Answer:
Before mountain building occurred, the area was underwater.
Explanation:
Through excavation, fossils that are of marine animals are often found high on mountain ranges. This seems weird from today's perspective, as marine animals can only be found in ocean waters, and there is no way they can travel on land and upon the mountains. Earth has changed a lot throughout history though, so such occurances are actually not that weird.
The mountains in Pennsylvania are such a place, with an abundance of marine fossils. When we look at the geological past of what is now Pennsylvania we can easily see why this is the case. The whole area was actually underwater for millions of years. This was the case before mountain building occurred here when part of the ocean floor raised high above the surface of the water and created land. As the crust was going up, the fossils on it went up as well.
1. the answer is A. temperature only
2. the answer is D. cooler, and saltier
Answer:
Higher temperature increases the speed of solubility
Explanation:
"Solubility" refers to the ability of a solute to be dissolved in a solvent. Solubility and temperature are <em>directly proportional</em>. This means that <em>as the temperature increases, the solubility of a substance increases too</em>. In the same manner, <em>as the temperature decreases, the solubility of a substance decreases too.</em>
High temperature produces<u> high heat (increase kinetic energy) that triggers the solvent to break the solutes apart.</u> This is mostly true for many solid-state solutions.
Answer:
<u>To bring awareness about the underwater volcanoes</u>.
Explanation:
- The eruption of the volcanoes, and the occurrence of the earthquakes on the planet and the spilling of the lavas, and the smoke-filled air hat comes to from the vent of the large craters.
- <u>As most people think that the volcanoes are present on the land areas only does not mean that they are confined to the above surface of earth they are also characterized by the deep hydrothermal vent and the most pope thus are surprised to know about them as they don't know that they are the primary place for the origin of the first life forms n the earth in the single-celled bacteria.
</u>
- They generally spill out the lavas and the magmas and this is called sth submarine volcanoes and ends to occur along the mid-ocean ridges. And are known to give out an estimated 75% of the volume of the lavas on earth.
- T<u>hey are also known as the seamounts that are created from the extinct volcanoes that occur in 1000 to 4000 meters depth of the seafloor.</u>
