Which is the site of highest geologic activity?

Answer: A volcano is a feature in Earth’s crust where molten rock is squeezed out onto the Earth’s surface. Along with molten rock, volcanoes also release gases, ash, and solid rock.

What are geological sites?

Local Geological Sites (formerly known as RIGS – Regionally Important Geological and Geomorphological Sites) exhibit important geological and geomorphological features and range from sarsen stones, rock outcrops to geological faces in active quarries.

What is the most powerful volcanic eruption in history?

The explosion of Mount Tambora is the largest ever recorded by humans, ranking a 7 (or “super-colossal”) on the Volcanic Explosivity Index, the second-highest rating in the index.

What are the most obvious landforms created by Lava?

volcanoes
The most obvious landforms created by lava are volcanoes, most commonly as cinder cones, composite volcanoes, and shield volcanoes. Eruptions also take place through other types of vents, commonly from fissures (Figure 1). The eruptions that created the entire ocean floor are essentially fissure eruptions.

  • 4500 mya – Earth’s core and crust formed.
  • 4400 mya – The Earth’s first oceans formed.
  • 3850 mya – The first life appeared on Earth.
  • 1500 mya – Oxygen began to accumulate in the Earth’s atmosphere.

    What is the biggest supervolcano in the world?

    Yellowstone
    The largest (super) eruption at Yellowstone (2.1 million years ago) had a volume of 2,450 cubic kilometers. Like many other caldera-forming volcanoes, most of Yellowstone’s many eruptions have been smaller than VEI 8 supereruptions, so it is confusing to categorize Yellowstone as a “supervolcano.”

    Which landform most likely formed when lava cooled and solidified?

    lava plateau
    Plateaus. A lava plateau is caused by a large amount of less viscous lava that flows over a large area. When it solidifies, it creates a large, flat surface of igneous rock.

    Which landforms are most likely created by the eruption of volcanoes?

    The way a volcano erupts and the materials that make up the magma and lava of a particular volcano have a lot to do with the formation of the volcanic landforms, such as craters, calderas, lava domes and lava plateaus.

    What are some examples of geological features?

    Examples of Geologic Features Erosion produces geologic features such as valleys, canyons, river channels, bays, caves and cliffs. A few geologic features that result from deposition are deltas, beaches, sand dunes and stalactites. Folds (bends) in sedimentary rock layers are a type of geologic feature.

    What are some of the most impressive volcanoes on other planets?

    Jupiter’s moon Io is home to some of the most impressive volcanoes around. Large plumes of gas and melted rock are ejected so high that they can be seen from far-away spacecraft. There are also hot lava flows.

    What is the best preserved impact crater on Earth?

    Barringer Crater is the best known and best preserved impact crater on Earth. The crater is named after Daniel Barringer who was first to suggest that it was produced by a meteorite impact. The crater is still privately owned by his family and is also simply known as Meteor Crater or Arizona Crater.

    Are there any active volcanoes in the Solar System?

    There are volcanoes all around our solar system. But only a few places besides Earth—like some of the moons of Jupiter, Saturn, and Neptune—have active ones today. Use the Space Volcano Explorer to learn more about our solar system’s many volcanoes.
