What are the 2 kinds of earthquake?

There are two types of earthquakes: tectonic and volcanic earthquakes. Tectonic earthquakes are produced by sudden movement along faults and plate boundaries. Earthquakes induced by rising lava or magma beneath active volcanoes is called volcanic earthquakes. What are the main types of earthquakes? There are four different types of earthquakes: tectonic, volcanic, collapse and explosion.

How is Coprolite formed?

Coprolites are the fossilized or preserved remains of the contents of the intestine and the excrement of organisms: fossilized feces. Coprolites are quite rare because they tend to decay rapidly. They are most commonly found among sea organisms. Coprolites of fish and reptiles are especially common. How are coprolite fossils formed? Older fossils, such as

What are sea caves made out of?

Sea caves are typically found in sandstone but also appear in other types of sedimentary rock, including limestone. They are less commonly formed in harder rock such as granite. How are sea cave made? sea cave, cave formed in a cliff by wave action of an ocean or lake. Sea caves occur on almost every

What damage did the Kashmir earthquake cause?

At least 79,000 people were killed and more than 32,000 buildings collapsed in Kashmir, with additional fatalities and destruction reported in India and Afghanistan, making it one of the most destructive earthquakes of contemporary times. How much damage did the Kashmir earthquake cost? In the village of Pehlwan, in the mountains of northern Pakistan, two

What is Pangea and continental drift?

The mechanism for the breakup of Pangea is now explained in terms of plate tectonics rather than Wegener’s outmoded concept of continental drift, which simply stated that Earth’s continents were once joined together into the supercontinent Pangea that lasted for most of geologic time. What is Pangaea and continental drift? According to the continental drift

What can diorite turn into?

What metamorphic rock does diorite turn into? Gneiss is a high-grade metamorphic rock. It is common only in areas of regional metamorphism. Several different rocks, such as granite, schist, and diorite can be metamorphosed to make gneiss. What does diorite change into? Diorite crystallized slowly within the Earth. That slow cooling produced a coarse grain

What type of volcano is Mount Etna?

Stratovolcano Mount Etna Geology Age of rock 350,000 – 500,000 years Mountain type Stratovolcano Last eruption – present Is Mt Vesuvius still active? Vesuvius is still regarded as an active volcano, although its current activity produces little more than sulfur-rich steam from vents at the bottom and walls of the crater. Vesuvius is a stratovolcano

What is the process of plucking?

Definition: Plucking is a process of erosion that occurs during glaciation. As ice and glaciers move, they scrape along the surrounding rock and pull away pieces of rock which causes erosion. Plucking. What is the process of plucking and abrasion? Abrasion involves scratching the bedrock with debris in the basal ice. Plucking is removal of

What areas in California are at the highest risk for earthquakes?

The greater San Francisco Bay Area has a high likelihood of future damaging earthquakes as it straddles the San Andreas fault system—the major geologic boundary between the North American and Pacific tectonic plates. What part of California gets the most earthquakes? San Francisco has the highest risk of an earthquake as it is located directly

What is the theme of Popocatepetl and Iztaccihuatl?

Popocatepetl and Iztaccíhuatl are the Aztec Romeo and Juliet – denied their love while alive but destined to spend eternity together. Now, as two volcanoes that set the backdrop for Mexico City, Izta and Popo, as they are affectionately called, are a symbol of love everlasting. What is the story of Popo and Itza? Even
