Describe why the earth experiences high and low tides.

The moon's gravitational force pulls on water in the oceans so that there are "bulges" in the ocean on both sides of the planet. The moon pulls water toward it, and this causes the bulge toward the moon. The bulge on the side of the Earth opposite the moon is caused by the moon "pulling the Earth away" from the water on that side.If you are on the coast and the moon is directly overhead, you should experience a high tide. If the moon is directly overhead on the opposite side of the planet, you should also experience a high tide.

During the day, the Earth rotates 180 degrees in 12 hours. The moon, meanwhile, rotates 6 degrees around the earth in 12 hours. The twin bulges and the moon's rotation mean that any given coastal city experiences a high tide every 12 hours and 25 minutes or so.

Hope this helps! :)

There are four methods to manage waste: recycling, landfilling, composting, and incinerating. Each method has its strengths and weaknesses. Recycling can reduce pollution, save materials, and lower energy use. However, collecting, processing, and converting waste uses more energy than it saves. Besides that, landfills can reduce greenhouse gas emissions at the same time it may pollute the local water supply. Furthermore, composting has a lower risk of pollution and odour and it reduces land disease. Despite, composting needs large amount of time and money. Last but not least, incinerating requires very little space. Alternatively, skill operators are needed to incinerate wastes.
