Sound, waves are all propagation of energy. Transport of this energy require a physical medium. Thus option D is correct.
What is mechanical waves?Mechanical waves are a form of energy transfer by oscillation of matter and they require a medium to propagate. Sound wave is a longitudinal wave which is only passing through a medium of air. Air disturbance causes these sound waves.
Longitudinal waves are those where the direction of oscillation of matter is along the direction of propagation. Electromagnetic waves does not require a medium to travel.
Waves in water originates from the pressure difference in water earthquakes is caused by seismic waves which are transverse waves, where the oscillation of matter is perpendicular to the direction of propagation.
Hence, sound, earthquakes, and waves in water are mechanical waves because they require a physical medium.

1. What are the different ways tectonic plates move in relation to each other?
2. What landforms could be the result of converging plates? name a location where this occurs.
3. What landforms could be the result of diverging plates? Name a location where this occurs.
4. What major event could occur as the result of transforming plates? Name a location where this can occur.
5. if crust is constantly created at divergent boundaries, why isn't Earth getting larger?
Answer + Explanation:
1. The different ways tectonic plates move in relation to each other are:
convergent (where plates move into one another)
divergent (where plates move apart)
transform (where plates move sideways in relation to each other)
2. Convergent plate boundaries can result in:
earthquakes, volcanoes, and the formation of mountains.
The Himalaya Mountains are the result of convergent plate boundaries.
3. Landforms that are a result of divergent boundaries are rift valleys and mid-oceanic ridges.
Locations where this occurs are: Mid-Atlantic Ridge, Red Sea Rift, Baikal Rift Zone
, East African Rift, East Pacific Rise, Gakkel Ridge, Galapagos Rise, and Explorer Ridge.
4. Transforming plate boundaries results in shallow earthquakes, large lateral displacement of rock, and a broad zone of crustal deformation.
A location where this occurs is: San Andreas Fault in western California

Which situation is an example of heat transfer by radiation?
Answer:
This type of transfer takes place in a forced-air furnace and in weather systems, for example. Heat transfer by radiation occurs when microwaves, infrared radiation, visible light, or another form of electromagnetic radiation is emitted or absorbed. An obvious example is the warming of the Earth by the Sun.
Answer:
the heat from the hotter to the colder region. Some common examples of Radiation are Ultraviolet light from the sun, heat from a stove burner, visible light from a candle, x-rays from an x-ray machine. All life on Earth depends on the transfer of energy from the Sun, and this energy is transferred to the Earth over empty space.

The minerals crystallize from materials dissolved in water from solutions that evaporate. Therefore, option B is correct.
What is mineral ?A mineral or mineral species is, generally speaking, a solid chemical compound that naturally occurs in pure form and has a very well-defined chemical composition as well as a particular crystal structure.
Each crystal structure that makes up a chemical compound that exists naturally as a separate mineral species. As an illustration, silicon dioxide is a component of the same mineral species as quartz and stishovite.
They can be mined and have the potential to be exploited as a source of metal. Manganese, iron ore, and bauxite are examples of metallic minerals, which can be either ferrous or non-ferrous. While ferrous minerals do contain iron, non-ferrous minerals do not.
Thus, option B is correct.
