An unusually large volcano having the potential to produce an eruptions with major effects on the global climate and ecosystem
What is... A Supervolcano
A hot spring that intermittently sends up fountainlike jets of water and steam into the air
What is... a geyser
A thermal spring having water warmer than 98°F (37°C): the water is usually heated by emanation from or passage near hot or molten rock
What is... a hot spring
How many calderas are at Yellowstone?
Three
What's the difference between a your average volcano and a super volcano?
A supervolcano has eruptions that are significantly larger that your average, run-of-the-mill volcano
a large, basinlike depression resulting from the explosion or collapse of the center of a volcano
What is... a Caldera
Where is the world's largest geyser?
Steamboat Geyser
Where is the world's largest hot spring pool?
What are the three different types of calderas?
Crater-Lake
Basaltic
Resurgent
What may happen after a Supervolcano eruption?
A dense, fast-moving flow of solidified lava pieces, volcanic ash, and hot gases; it occurs as part of certain volcanic eruptions
What is... Pyroclastic Flow
*DAILY DOUBLE*
About how much of the worlds population of geysers are located in Yellowstone National Park?
2/3rds
(T/F) There is no risk from swimming in a hot spring
F, deadly parasites are often found in hot springs
What caldera at Yellowstone is the largest?
The Yellowstone Caldera
How would the midwest be affected by Yellowstone's supervolcano?
it would be blanketed by glass and rock; plants and animals would die; roofs and electrical equipment would be destroyed
Noting or pertaining to the action of hot aqueous solutions or gases within or on the surface of the Earth
What is... hydrothermal
Why is the Old Faithful geyser so rare?
It erupts more often than the average geyser
What is the average temperature of a hot spring?
98° Fahrenheit
36.7° Celcius
How is a caldera formed?
When magma causes the top of the volcano to collapse inward
What states would be affected by the Yellowstone National Park super-volcano's pyroclastic flow?
Montana, Idaho, Wyoming
A region of molten rock below and within the lithosphere that persists long enough to leave a record of uplift and volcanic activity at the Earth’s surface
What is... a hot spot
How are geysers formed?
Geysers are created by thermal water beneath the Earth’s surface that becomes super heated by magma and trapped in a tunnel. When more water is added, the heat and pressure caused the hot water to erupt from the ground.
How are hot springs formed?
when water is heated by magma and flows towards the mantle, and come in contact with hot rocks that heat the water up. most common way is when rainwater or groundwater is heated by magma underneath Earth’s surface. Cracks or faults in the Earth’s surface allow water to flow deeper towards the mantle, where it comes in contact with hot rocks. Those rocks then heat the water up.
What is the youngest caldera at Yellowstone?
Lava Creek
About how many years ago did Yellowstone's Supervolcano last erupt?
70,000
