In which state of matter are particles closest together?
In the solid state of matter, particles are closest together. This is due to the fact that solids have a definite shape and volume, meaning the particles are tightly packed in a fixed, orderly arrangement. In comparison:
Liquids have particles that are close together but not in a fixed position, allowing them to flow.
Gases have particles that are far apart and move freely.
Plasma consists of ionized particles and is not typically considered in the context of ordinary matter states at standard conditions.

A system of underground pipes heated by Earth s hot interior creates steam from water, which generates heat for a building.
Which type of energy source is harnessed in this scenario?
The scenario describes a geothermal energy system. Geothermal energy harnesses the heat from the Earth's interior to generate steam, which can then be used to produce electricity or provide direct heating. In this case, underground pipes circulate water that is heated by the Earth's internal heat, turning it into steam to generate heat for a building. Reference:
A heavy rain produces runoff.
Which reservoir does the water become a part of during this runoff process?
When heavy rain occurs, the water that does not infiltrate into the ground or evaporate runs off over the land surface. This runoff water collects in rivers, lakes, and streams, becoming part of the surface water reservoir. Surface water is the body of water above ground, including rivers, lakes, reservoirs, and oceans, which is replenished by precipitation and runoff.

Which process is responsible for the formation of the sand dune pictured above?

The formation of sand dunes, as shown in the picture, is primarily due to the process of deposition by wind. Wind transports sand and other fine particles over long distances, and when the wind speed decreases, these particles settle and accumulate, forming dunes. This process is particularly common in arid and semi-arid regions where vegetation is sparse, allowing the wind to move freely.
