Similar to shrimp, the jury is still out on whether or not crab is safe to feed to your pet. Thereâs a chance that if fed in small portions, your dog should be fine. However, crab contains a lot of iodine, which many dogs are allergic to. These types of shellfish are fine for dogs to eat in moderation.
A strait is a naturally formed, narrow, typically navigable waterway that connects two larger bodies of water. Most commonly it is a channel of water that lies between two land masses. Some straits are not navigable, for example because they are too shallow, or because of an unnavigable reef or archipelago.
The transition between river and ocean, bay or lake is known as a delta. Most rivers have a delta, an area where the river divides into many channels and river water mixes with sea or lake water as the river water reaches the end of its journey.A famous example of a delta is where the Nile River meets the Mediterranean Sea in Egypt, called the Nile Delta. river grows larger as it collects water from more tributaries. Streams usually form rivers in the higher elevations of mountains and hills. The areas of depression between hills or mountains are known as valleys.
