Magma, this burning liquid rock beneath the Earth's surface, largely determines a volcano's ability to erupt. Its texture, called viscosity, directly influences its activity: fluid...
Crescent City is located on the northwestern coast of California, not far from the border with Oregon, directly across from the Pacific. The big issue...
Iceland is somewhat like the center of the world when it comes to volcanoes. Located at the boundary of two tectonic plates, North America and...
Volcanoes primarily form when magma, a mixture of partially melted rock, reaches the Earth's surface. This magma comes from the Earth's mantle, a semi-liquid layer...
Salt crystals form in deserts due to the massive evaporation of water. Deserts, with their dry and hot climate, are perfect for this phenomenon. When...
Natural hot springs primarily occur when rainwater or meltwater seeps into the ground, descends deep, and then heats up in contact with areas of geothermal...
May 29, 1953, a date to be marked with a white stone. Sir Edmund Hillary from New Zealand and Tenzing Norgay, a Nepalese Sherpa, were...
Limestone is a sedimentary rock primarily composed of calcium carbonate. Due to its origin, it is often very porous. What is porosity? Like a sponge, it's the...
Tectonic plates are enormous pieces of the Earth's crust that constantly move. Beneath the ocean, these plates shift, move apart, or collide. When they move...
Some volcanoes have a magma chamber directly connected to the surface. When the magma rises, it can form permanent pools, called lava lakes, directly visible...
