B) 1530 m/s

First, you must double the distance since the wave is traveling to the ocean floor and back to the vessel. The distance is 4600 meters x 2 or 9200 meters. Next, use the speed formula to solve for average speed: v = d/t. 9200m/6s = 1530 m/s.

Seasonality involves the variability of both hours of daylight and the altitude of the Sun.
jarptica [38.1K]

Answer:

True

Explanation:

Season refers to the changes that occur on earth that are commonly marked by the variation in the climate, amount of sunlight and also the weather condition. It is mainly caused due to the tilting of the earth's imaginary axis and also due to the orbital motion of the earth around the sun.

The duration of daylight and the altitude of the sun changes with the changing climate. During the summer, the days are longer and during the winter season, the days are shorter. Also, during the winter, the earth comes closer to the sun but due to the presence of its tilt, the amount of sunlight that falls on it is reflected back into space. So, during winter, the temperature remains cold, and in summer, the opposite happens.  

In the winter season, the Sun reaches a maximum of 46.56° in terms of altitude and 93.44° of altitude during summer.

Hence, the above-given statement is True.
