By looking at the satellite photograph below that shows the Mississippi River entering the Gulf of Mexico, the depositional feature in the Gulf of Mexico is best identified as a delta. A delta is when a river will divide itself into many other rivers and then goes into a larger water body.
Answer:
The water in ocean, lakes and rivers are heated by the Sun, sunlight hits the ocean which is dispersed by the first 1000 meters of the oceans surface. This hot water is mixed with the cold water at the bottom of the ocean by ocean waves and this is the reason why ocean waves are at a regular temperature.
In a lake the water is heated the same way but there is not much water to mix the hot water with the cold so the water in the lake seems hotter than the ocean.
In a river the water keeps on flowing which mixes the hot water with the cold and the temperature remains regular.
Explanation:
Sound is a wave which is created by vibration, and these sound waves can travel in different mediums for example, air, liquid and even solid.
