Answer:
Alluvium
Explanation:
Unlike solid rock Alluvium is loosely compacted, unconsolidated eroded
soil or sediment that has been reshaped by water and redeposited in a non-marine environment. It is typically made up of a various materials, such as fine
silt and clay particles and large sand particles as well as gravel. When alluvial material is consolidated into a lithological unit, or lithified, it is known as an alluvial deposit.
Distances in space could be measured in common units of length, such as miles or kilometers. But measuring such large distances in these common units creates some pretty big numbers. It's easier to measure distances in two alternate units of distance- light years and astronomical units.

Answer:
1. Heating hydrogen gas from 60°C to 80°C: Entropy increases
2. Subliming dry ice: Entropy increases
3. Forming sucrose crystals from a supersaturated solution: Entropy decreases
4. Condensing water: Entropy decreases
Explanation:
Entropy is a measure of systems disorder. The higher the entropy the higher the disorder. So for the firs example if we heat a gas, molecules move faster, disorder is higher. For second example we are making disordered gas from very ordered crystals also increase in disorder. For 3rd example we are obtaining crystals which brings order. And for the fourth example we make liquid from gas which is also more order.
