Answer:
Option (1)
Explanation:
A fjord is usually defined as a contrasting geological landform, which is typically a U-shaped valley, that is formed due to the movement of the glaciers. It is generally narrow and forms steep-sided cliffs on both the sides and is mostly connected to the seas. They have huge depth, sometimes reaches up to a depth of about 1300 m. The downward flowing glaciers pushes the terminal moraine and allows it to remain underwater at its entrance, resulting in shallow water at the fjord's neck, in comparison to the main body of the fjord that is located behind it.
Thus, the correct answer is option (1).
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.
