For every one kilometer higher above sea level, temperature drops by 1 degree. The higher the location above sea level the lower the temperature.
Mauna Loa in Hawaii is the largest active volcano on our planet but the world's smallest active volcano is the Taal Volcano in the Philippines.Taal Volcano has a 406-meter-high crater.

The lowest point of dry land on the surface of the Earth is the shores of the Dead Sea between Israel and Jordan. It is 420 meters below sea level (1,378 ft). The Dead Sea is the world's second saltiest body of water after Lake Asal in Djibouti. It is 8.6 times saltier than the ocean.

Based on photos taken from satellites, the Atlantic Ocean is getting wider by 5-10 cm. a year.

Noticed how South America and Africa and other continents seem to fit altogether.
