There are four important warning signs that should prompt you to talk to a health care provider. 1  Pain. Pain from arthritis can be constant or it may come and go. 2  Swelling. Some types of arthritis cause the skin over the affected joint to become red and swollen, feeling warm to the touch. 3  Stiffness.
There's a whole lot of water on Earth! Something like 326,000,000,000,000,000,000 gallons (326 million trillion gallons) of the stuff (roughly 1,260,000,000,000,000,000,000 liters) can be found on our planet. This water is in a constant cycle -- it evaporates from the ocean, travels through the air, rains down on the land and then flows back to the ocean.
The Pacific Ocean is estimated to contain 187 quintillion gallons of water. That quantity is equal to about one-third of the water of all the oceans. The Pacific Ocean is by far the largest body of water on Earth, stretching from the Arctic in the north to Antarctica in the south with a maximum depth of more than 11,000 meters. The Pacific Ocean moves clockwise in the Northern Hemisphere and counter clockwise in the Southern Hemisphere.
