What happens when new oceanic lithosphere is generated at an oceanic ridge?

  • When new oceanic lithosphere is generated at an oceanic ridge, what happens to the plate it’s attached to? The plate gets larger. You are dropped off by helicopter at a site on the land. You are told that it is a plate boundary. Almost immediately, you feel an earthquake.

What type of volcanic structure is Shiprock New Mexico and how did it form?

What type of volcanic structure is Shiprock , in New Mexico, and how did it form ? Shiprock is a volcanic neck. It consists of igneous rock that crystallized in the vent of a volcano . The less-resistant rock surrounding this rock eroded away, leaving the volcanic neck standing high on the landscape.

What best describes a volcano?

A volcano is a hole in Earth’s surface through which magma (called lava when it reaches Earth’s surface), hot gases, ash, and rock fragments escape from deep inside the planet. The word volcano also is used to describe the cone of erupted material (lava and ash) that builds up around the opening.

What Magma is the most abundant?

basaltic

What volcanic events formed Crater Lake Oregon?

Crater Lake partly fills one of the most visually spectacular calderas of the world, an 8-by-10-km (5-by-6-mi) basin more than 1 km (0.6 mi) deep formed by collapse of the volcano known as Mount Mazama during a series of explosive eruptions about 7,700 years ago.

What type of structure is Shiprock New Mexico and how did it form quizlet?

Shiprock , New Mexico is a volcanic neck that formed when the volcano itself eroded away, leaving the crystallized igneous rock piercing through the Mancos shale.

Where do most shield volcanoes form quizlet?

Shield volcanoes mostly occur at divergent boundaries. Specifically, they can occur in rift valleys and mid-ocean ridges, which all form at divergent boundaries themselves. They also form at hotspots.

What are the description of volcano?

A volcano is a mountain that opens downward to a pool of molten rock below the surface of the earth. When pressure builds up, eruptions occur. In an eruption, gases and rock shoot up through the opening and spill over or fill the air with lava fragments. More than 80% of the earth’s surface is volcanic in origin.

What is volcano in simple words?

A volcano is an opening in the earth’s crust through which lava, volcanic ash, and gases escape. Volcanic eruptions are partly driven by pressure from dissolved gas, much as escaping gases force the cork out of a bottle of champagne.

What words describe a volcano?

Here are some adjectives for volcano : highest active, northernmost active, largest active, deepest undersea, historically active, greatest active, impossibly gargantuan, grimly cold, conical extinct, volcanoes –artificial, blinding, silent, barely quiescent, small and probably extinct, probably extinct, massive extinct

Which magma type has the lowest viscosity?

Basaltic

Which lava compositions has the greatest viscosity?

High-silica, low-temperature lavas are the most viscous and allow the greatest amount of pressure to build before they “let go” in an eruption. The low-silica, high-temperature produces a runny less viscous magma , less pressure can build up and will produce relatively gentle eruptions.

Is Crater Lake a supervolcano?

Crater Lake partially fills a type of volcanic depression called a caldera that formed by the collapse of a 3,700 m (12,000 ft) volcano known as Mount Mazama during an enormous eruption approximately 7,700 years ago. The caldera wall displays the geologic layering of lava flows through time.

Is the Kikai Akahoya volcano still active?

Kikai is still an active volcano . Minor eruptions occur frequently on Mount Iō, one of the post-caldera subaerial volcanic peaks on Iōjima. Iōjima is one of three volcanic islands, two of which lie on the caldera rim. Mexico
