Answer: D. It can melt to a depth of a few meters in summer, then refreeze in winter.
Explanation:
Permafrost is ground which remains frozen for two or more years. Permafrost consists of soil, rock and sand fused together by ice. Mostly found in areas in high altitude, the Arctic, Antarctica, it is common in periglacial environments where temperatures are below freezing
.
The topmost layer of permafrost can melt in summer and refreeze in winter. This thawing and refreezing produces a ground pattern called columnar joints similar to the one formed when molten lava cools.
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.
