Cosiguina Volcano, Nicaragua
Three Central American countries—El Salvador, Honduras, and Nicaragua—have coastline along the Gulf of Fonseca, which opens into the Pacific Ocean. The southern boundary of the Gulf is a peninsula formed by the Cosigüina Volcano. Cosigüina is a stratovolcano, which is a cone-shaped volcano formed by alternating layers of solidified lava and volcanic rocks produced by explosive eruptions.

216 x 144 JPEG
Snow cover and land temperature are connected, but one does not necessarily cause the other. Snow certainly influences how hot or cold the land feels to the touch, and land temperature influences whether or not snow remains on the ground or melts away. But the most obvious global pattern these images demonstrate is not the effect of temperature and snow cover on each other, but the effect of latitude and elevation on each.
