Explanation:

Question 8

The question asks for the term of icicle - shaped formations in caves formed by deposition. In geology (a subfield of Natural Science, specifically Geography or Earth Science), these formations are called stalactites. Stalactites hang from the cave ceiling and are formed as mineral - rich water drips and deposits calcium carbonate over time.

Weathering is a process in geology (part of Natural Science, Geography/Earth Science). It is the breakdown or alteration of rocks, minerals, and other materials on the Earth's surface. There are two main types: mechanical (physical) weathering, which breaks rocks into smaller pieces without changing their chemical composition (e.g., freeze - thaw, exfoliation), and chemical weathering, which changes the chemical makeup of rocks (e.g., oxidation, hydrolysis).

Mechanical weathering is more common in climates with frequent temperature changes, especially those with freezing and thawing cycles (e.g., cold climates with seasonal freeze - thaw, or areas with daily temperature fluctuations across the freezing point like some mountainous or temperate regions). Also, dry climates with strong winds (for abrasion) or wet - dry cycles (for salt crystal growth) can favor mechanical weathering. A climate with frequent freeze - thaw cycles (e.g., a cold climate with alternating freezing and thawing) is a prime example as water in rock cracks freezes, expands, and breaks the rock.

Answer:

Stalactite
