Sent by Brie. Editor: Brie, fennel is a bulbous vegetable with a tall, wispy, fronded top that looks rather like dill. The fronds can be used in salads, but the main attraction of fennel is the bulb itself. It's very firm and crunchy, and it tastes a bit like licorice and anise. It has a fresh, bright taste and it's one of our favorite vegetables for salads and slaws. It can also be grilled or braised until tender.
Origin of the Ocean Basins. The ocean basins are the result of tectonic forces and processes. All of the ocean basins were formed from volcanic rock that was released from fissures located at the mid-oceanic ridges. The oldest rocks found in these basins are approximately 200 million years old. This is a lot younger than the oldest continental rocks which have ages greater than 4 billion years.
The ocean trenches are narrow topographic depressions in the sea. These trenches form the deepest points in the ocean and are the lowest points on earth. These trenches are formed at a particular place of plate boundary which is known as subduction zone.It happens to form when a plate in ocean hits another ocean plate or it strikes with continental plate.ow when one plate hits another plate or continental plate in the ocean then the denser plate between the two of them sinks in the mantle. The place where this plate sinks will create a deep trench on that spot of ocean.
