Volcanoes
How are volcanoes formed?
Volcanoes are formed when molten rock (magma) rises to the surface through a vent or opening in the Earth's crust.
What causes an earthquake?
Earthquakes are caused by the sudden release of energy in the Earth's crust, usually resulting from the movement of tectonic plates.
What causes a tsunami?
Tsunamis are generally caused by underwater disturbances, such as earthquakes, volcanic eruptions, or landslides, that displace large volumes of water.
How are rock layers formed?
Rock layers are formed through the deposition of sediment, such as sand, mud, or organic material, over time. This process is known as sedimentation.
What grade did Ms. Thomas teach before?
Will accept: K, 1, 2, 4, and 6
What is the main difference between a dormant volcano and an extinct volcano?
A dormant volcano is currently inactive but has the potential to erupt again, while an extinct volcano is no longer active and is unlikely to erupt again.
What is the point deep beneath the Earth's surface where an earthquake starts called?
The point deep beneath the Earth's surface where an earthquake starts is called the focus or hypocenter.
What is a tsunami wave made up of?
A tsunami wave is made up of a series of long ocean waves, typically caused by the displacement of a large volume of water.
What does the order of rock layers tell us about the age of the rocks?
The order of rock layers can provide information about the relative age of the rocks. In general, the deeper the rock layer, the older it is compared to the layers above it.
Where is Ms. Thomas from?
What happens when a volcano erupts?
When a volcano erupts, it releases lava, ash, gases, and volcanic rocks into the air and onto the surrounding area. It can also create pyroclastic flows, lahars, and volcanic explosions.
How are the strength of earthquakes measured?
The strength of earthquakes is measured using a seismograph, which records the seismic waves produced by an earthquake. The magnitude of an earthquake is measured using the Richter scale or the moment magnitude scale.
What is the first sign of a tsunami approaching the shore?
The first sign of a tsunami approaching the shore is often a noticeable and rapid recession of water from the shoreline, exposing the seabed.
What are fossils?
Fossils are the preserved remains or traces of ancient organisms, such as plants, animals, or microorganisms, that have been preserved in rock.
What is Ms. Thomas' favorite pokemon?
Psyduck
Which type of volcano is characterized by large, explosive eruptions and a broad, gently sloping cone?
A stratovolcano, also known as a composite volcano, is characterized by large, explosive eruptions and a broad, gently sloping cone.
What is the term for smaller earthquakes that occur in the same area before and after a larger earthquake?
The term for smaller earthquakes that occur in the same area before and after a larger earthquake is foreshocks and aftershocks.
What does the word "tsunami" mean in Japanese?
The word "tsunami" means "harbor wave" in Japanese.
What can we learn from studying rock layers and fossils?
Studying rock layers and fossils can provide insights into the Earth's history, including past environments, the evolution of life forms, and the occurrence of major geological events.
Where did Ms. Thomas go to College?
UCF, Orlando
Name one famous volcano that is known for its eruption in 79 AD.
Mount Vesuvius is the famous volcano known for its eruption in 79 AD that buried the cities of Pompeii and Herculaneum.
What is the largest instrument used to measure earthquakes called?
The largest instrument used to measure earthquakes is a seismograph or a seismometer.
Where do most tsunamis occur?
Most tsunamis occur in the Pacific Ocean, particularly in the "Ring of Fire," which is a region of intense seismic activity.
Why do rock layers sometimes appear tilted or folded?
Rock layers can appear tilted or folded due to tectonic forces, such as the collision of tectonic plates or the movement of faults, which can deform and reshape the originally horizontal rock layers.
What was Mr. Matteson and Ms. Thomas's trivia team name?
Fairley Good Guessers
