Give a reason for each of the following:

1. Newfoundland has rich fishing grounds.
2. The eastern coast of Japan is warm even in January.
3. The tidal range differs from one water body to the other.

1. Newfoundland, where Gulf stream (warm) and Labrador (cold) currents meet has rich fishing ground, because the mixing of the cold and warm currents provides ideal temperature conditions for the life of fish.
2. The eastern coast of Japan is warm even in January because of warm Kuroshio Current. It is the most important warm current of North Pacific Ocean. It's average temperature remains 18°C.
3. The tidal range differs from one water body to the other. In the open oceans such as Atlantic, tides flow and ebb regularly twice a day. The difference in height between high and low tides, may be only a half metre, but in shallow marginal sea, it can increase upto 10 metres. In the enclosed seas or sheltered seas such as Mediterranean or Baltic, the range may be very small.
