Answer:
The correct answer is Secondary Waves (S).
Explanation:
When the rocks inside the earth suddenly break, or an exploration occurs, seismic waves are generated.
When an earthquake occurs, the secondary waves (S)are the second to reach a seismometer. This type of waves is known as body waves and they travel through the interior of the Earth instead of moving over the surface.
The waves that arrive first are the Primary (P) waves that are the fastest type of seismic wave, therefore they are the first to reach a seismograph.
S waves arrive second after an earthquake.
S waves are also known as secondary waves, hence why they arrive second after an earthquake.

They formed Gondwana.
They moved toward the poles.
Answer:
The trade winds (also called trades) are the prevailing pattern of easterly surface winds found in the tropics near the Earth's equator, equatorward of the subtropical ridge. These winds blow predominantly from the northeast in the Northern Hemisphere and from the southeast in the Southern hemisgere.
c. longshore currents
b. breakers
d. wind
Answer:
c. longshore currents
Explanation:
The main chemical process that is observed in the coasts is the one of dissolution, that is to say, the water of the sea is able in this case to dissolve the rocks, causing cavities or isolating fragments and conferring them peculiar structures.
The influence of living beings around the shape of the coast has been slow and continuous; For example, as they grow, the colonies that form coral reefs are forming great barriers that modify the coast.
The internal agents correspond to the characteristics of the structure of the rocks of the coast, such as their nature and degree of hardness, the abundance and size of loose materials, the depth of the sea in the vicinity of the shore.
Erosion of rocky shores caused by waves happens slowly, even in places where the rocks are relatively soft. The erosion rates per year on the cliffs are one meter, and represents approximately 5 percent of the erosion material that reaches the world's beaches.
In the modeling of the coast, the movement of sediments along the banks is also important. For example, the amount of beach sand that is transported on several coasts can reach a volume greater than one million cubic meters per year.
The main sources of beach and shore sediments are represented by rivers, which carry large amounts of sand to the ocean; the marine cliffs of unconsolidated material, which are worn by the waves, and the remains of biological origin, such as shells, coral fragments and other skeletons of small marine organisms. Wind-dragged sand can act as a source of sediment on the banks, although winds are generally more effective by removing sand from beaches than by depositing it.
The answer is actually C, Longshore currents.

The correct answer is - Focus.
Focus of the earthquake, also referred to as hypocenter, is the location/point where the earthquake starts. It is usually few kilometres below the surface. At this spot the ground raptures after which seismic waves start radiating outward in all directions. The focus is located below the epicenter, or rather the epicenter is above it because the location of the epicenter is determined by the location of the focus, so the epicenter represents the closest point on the surface of the Earth from where the focus is.
