Evidence Earth’s Interior is Hot Record the evidence you find in these photographs from places in the United States

Hawaiian volcano erupting lava which comes from the magma(molten rock) in the Earth’s interior. Erupting lava averages around 2,000 degrees fahrenheit.

Stone Mountain - a dome mountain created from a magma pool that cooled

Mount Saint Helens is a volcanic mountain located in the state of Washington. Last major eruption was May 1980.

Old Faithful geyser Yellowstone National Park Old Faithful geyser Yellowstone National Park. The park sits in the caldera of a volcano. Magma near the surface (37 miles) superheats underground water and gases that build pressure until the geyser erupts.

Devil’s Tower Wyoming, created from magma that cooled while in a vent of a volcano. The volcano has eroded away.

Hydrothermal ocean vents spew superheated seawater containing minerals Hydrothermal ocean vents spew superheated seawater containing minerals. Magma under the ocean floor superheats seawater reaching temperatures over 700 degrees fahrenheit. Gases build constant pressure causing an uninterrupted eruption.

Morning Glory hot spring pool in Yellowstone National Park Morning Glory hot spring pool in Yellowstone National Park. Water is heated from a magma chamber near the surface(about 37 miles). Bacteria create the colors. Water temperatures in hot springs at Yellowstone average from 69-160 degrees but the highest temperatures have been recorded at 459 degrees fahrenheit.

The Ring of Fire is the location around the Pacific Ocean rim where 90% of all volcanoes and earthquakes occur on Earth.

Yellowstone National Park mud pot Yellowstone National Park mud pot. Silted water is heated from magma close to Earth’s surface averaging temperatures around 200 degrees fahrenheit.

Lava flow on Hawaii. Lava flow temperatures average around 1,000 degrees fahrenheit.

Mammoth Hot Spring deposits at Yellowstone National Park with water ranging in temperatures from 70 to 160 degree fahrenheit. The highest temperatures have been recorded at 459 degrees fahrenheit.

Ancient lava tube in Black Rock Utah Ancient lava tube in Black Rock Utah. Pictured on the left is the end of one of the many tubes which extend hundreds of yards.This one is called Tabernacle Hill. The entrance to one of the tubes is pictured to the right. Pictured at the bottom right is a person sanding inside a lava tube in Hawaii.

Crater Lake Oregon volcano Crater Lake Oregon volcano. The Island, called Wizard Island, is a cinder cone volcano within the collapsed caldera of the larger volcanic mountain.

Erupting Volcano in the northeastern US

Hot springs at Yellowstone National Park ranging 70-160 degrees fahrenheit on average but the highest temperatures have been recorded at 459 degrees fahrenheit.

Lava flows from nonexplosive eruptions creating new land surface features.

Kanaga volcanic mountain in Alaska

Ocean floor lava flows emerging from cracks in the seafloor called faults.

Fumaroles at Yellowstone National Park Fumaroles at Yellowstone National Park. Fumaroles are different from geysers in that fumaroles release mosly gasses averaging 320 degrees fahrenheit and very little water.
