Questions and Answers

What's a volcano?
- A.
A rupture on an elevated surface
- B.
An opening on a mountain
- C.
A hot disposition of lava
- D.
None of the above
Correct Answer
A. A rupture on an elevated surfaceExplanation
A volcano is a rupture on an elevated surface. This refers to the opening or vent on the Earth's surface through which molten rock, gases, and volcanic ash are expelled during a volcanic eruption. Volcanoes are typically found on mountains or elevated areas, and the rupture allows for the release of pressure and the escape of volcanic materials from beneath the Earth's crust.Rate this question:

What do volcanoes do?
- A.
They explode
- B.
They allow lava to erupt
- C.
They destroy the earth
- D.
None of the above
Correct Answer
B. They allow lava to eruptExplanation
Volcanoes allow lava to erupt. Volcanic eruptions occur when molten rock, known as magma, rises to the surface through cracks in the Earth's crust. Once the magma reaches the surface, it is called lava. Volcanoes act as vents or openings through which this molten rock can escape, resulting in eruptions. These eruptions can be explosive, with the lava being ejected forcefully into the air, or they can be more gentle, with the lava flowing slowly out of the volcano. In either case, volcanoes are responsible for the release of lava onto the Earth's surface.Rate this question:

Where does lava escape from?
- A.
Magma chamber
- B.
The mountains
- C.
The edges
- D.
None of the above
Correct Answer
A. Magma chamberExplanation
Lava escapes from the magma chamber. The magma chamber is a large underground reservoir where molten rock, or magma, is stored. When pressure builds up within the chamber, the magma can erupt to the surface as lava through volcanic vents or fissures. This process is responsible for the formation of volcanic eruptions and the release of lava onto the Earth's surface.Rate this question:

Which word is volcano gotten from?
- A.
Vokano
- B.
Vulcano
- C.
Vogano
- D.
Vulkanu
Correct Answer
B. VulcanoExplanation
The word "volcano" is derived from the word "Vulcano". The spelling "Vulcano" is the closest option to the original word and matches the correct answer.Rate this question:

What do vocanic winter cause one of the following.
- A.
Winter
- B.
Famine
- C.
Liposuction
- D.
Dryness
Correct Answer
B. FamineExplanation
Volcanic winter can cause famine because the eruption of a volcano can release large amounts of ash and gases into the atmosphere, blocking sunlight and reducing temperatures. This can disrupt the growing season for crops, leading to crop failures and food shortages. Additionally, the ash can contaminate water sources and destroy agricultural land, further exacerbating the food crisis. Famine occurs when there is a severe scarcity of food, and the volcanic winter caused by a volcanic eruption can contribute to the occurrence of famine.Rate this question:

Subductions are usually one of the following.
- A.
Where two collide
- B.
Where two are joined together
- C.
Where two are melted
- D.
None of the above
Correct Answer
A. Where two collideExplanation
The correct answer is "Where two collide." This is because subductions occur when two tectonic plates collide, and one plate is forced beneath the other, causing a subduction zone. This process is commonly observed in areas where oceanic plates collide with continental plates, resulting in the formation of trenches and volcanic activity.Rate this question:

What are hotspots?
- A.
Internet
- B.
Volcanic area
- C.
Lava rush
- D.
None of the above
Correct Answer
B. Volcanic areaExplanation
Hotspots refer to areas on the Earth's surface where volcanic activity is concentrated. These areas are characterized by a high concentration of volcanic eruptions, which occur due to the movement of tectonic plates over a stationary hotspot beneath the Earth's crust. As the tectonic plate moves, a new volcano forms over the hotspot, while the older ones move away from it. This explains why volcanic activity is often found in specific regions, such as the Hawaiian Islands or the Yellowstone National Park, making "Volcanic area" the correct answer.Rate this question:

What is formed by hotspots?
- A.
Hawaii
- B.
Dellas
- C.
Taxes
- D.
Pennsylvania
Correct Answer
A. HawaiiExplanation
Hotspots are areas where there is an upwelling of magma from deep within the Earth's mantle. This magma creates volcanoes on the Earth's surface, and over time, as the tectonic plates move, a chain of volcanoes is formed. Hawaii is a prime example of a hotspot, as it is a chain of volcanic islands that were formed by the movement of the Pacific Plate over a hotspot.Rate this question:

What is the prominent feature of volcanoes?
- A.
Lava
- B.
Conical head
- C.
Heat
- D.
None of the above
Correct Answer
B. Conical headExplanation
Volcanoes are characterized by their conical head, which refers to the shape of the volcano. The conical head is formed by layers of solidified lava, ash, and other volcanic materials that have erupted from the volcano over time. This distinctive shape is a result of the accumulation and deposition of these materials, creating a steep-sided cone-like structure. The conical head of a volcano is one of its most prominent features and helps to distinguish it from other geological formations.Rate this question:
