You probably know that the majority of our planet's surface is covered by bodies of water. Submersibles must be incredibly strong and resilient to contend with strong ocean currents, no visibility, and intense pressure of the Mariana Trench. One of the many effects of climate change is that the thermohaline circulation of the Atlantic Oceanthe system that balances the ocean by keeping warm and cool currents moving in the right directionis slowing down.

On April 12, 1929, President Herbert Hoover signed presidential proclamation No. Sea stars can reproduce sexually. It's true. The Aral Sea is a shallow, large brackish lake concealed in remote deserts between two countries. This refraction of waves concentrates their energy in specific locations along the headland, causing particularly rapid erosion if weakness such as faults and fractures are present in the rocks. The tourists wait for the whole day to visit the high tice wave and the highest tide visited till today is about 16 meters in height although waves vary from day today.
