What causes the sudden movements of the earth?

  1. Volcano

  2. Folding

  3. Flood plain

  4. All of the above
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Sudden movements of the earth can be noticed during the eruption of a volcano. Sudden movements, caused by sudden endogenetic forces coming from deep within the earth, cause such sudden and rapid events that these cause massive destruction at and below the earth's surface. These forces work very quickly and their results are seen within minutes.

In some eruptions, mud flows are forced over the ________.

  1. earth's mantle

  2. ocean bed

  3. earth's surface

  4. earth's core
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Mud flows are a flowage of water-saturated earth material possessing a high degree of fluidity during movement. A less-saturated flowing mass is often called a debris flow. A mudflow originating on the flank of a volcano which generally flows through the surface of the Earth.

Magma which is forced onto Earth's surface is known as _________.

  1. vent

  2. cone

  3. lava

  4. magma chamber
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation
  • Magma, when comes out on the surface of the earth through the volcanic opening, is called lava, hence option C is correct.
  • The vent is the volcanic opening on earth's surface.
  • Cone is the structure of the volcano formed as a heap of cooled materials that come out of volcanic eruptions
  • The magma chamber is the pool of magma beneath the surface of the earth.

Funnel shaped mouth of a volcano is called _____.

  1. Vent

  2. Crater

  3. Chamber

  4. Lava
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Volcanic crater is a circular depression in the ground caused by volcanic activity. It's typically a basin, circular in form within which occurs a vent from which magma erupts as gases, lava, and ejecta. A crater can be of large dimensions, and sometimes of great depth.

Which is caused by the smaller movements of the earth?

  1. Flood plain

  2. Beach

  3. Volcano

  4. Folding
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Volcanic activity frequently occurs at the boundaries of the Earth's tectonic plates which are a series of large moving blocks. The movement of these plates plays a significant role in the type of volcano formed, which influences its shape. If the movement is smaller, they leads to volcanic eruptions. Larger movements may lead to earthquakes.

Mt. Aconcagua in South America is an __________.

  1. extinct volcano

  2. dormant volcano

  3. active volcano

  4. none of these

A Correct answer
Explanation

Aconcagua is the highest mountain outside Asia, at 6,961 metres and by extension the highest point in both the Western Hemisphere and the Southern Hemisphere. Aconcagua is of volcanic origin, but it is not an active volcano and cab be considered as extinct.

When a volcano ejects acidic lava, eruption is usually ____________.

  1. Light and less violent

  2. Soft and less violent

  3. Loud and less violent

  4. Loud and more violent
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

When a volcano ejects acid lava, they are loud and violent usually because of the explosive pressures building up in magma. They eject acid lava, ash, gases and rock fragments. They are dangerous as materials can rain down on settlements. Ex: Eruptions at Krakatoa in Indonesia.

Mt. Kenya is an Extinct volcanoes in __________.

  1. South America

  2. Africa

  3. Europe

  4. Australia
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Mount Kenya is the second highest mountain in Africa, after Kilimanjaro. Mount Kenya is a stratovolcano created approximately 3 million years after the opening of the East African rift. Before glaciation, it was 7,000 m high. It was covered by an ice cap for thousands of years. This has resulted in much eroded slopes and numerous valleys radiating from the centre.

Frequency of eruption serves as the basis of classification of volcanoes. Which of the following is not in this category?

  1. dormant volcanoes

  2. active volcanoes

  3. composite volcanoes

  4. extinct volcanoes
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

An active volcano is a volcano that has had at least one eruption during the past 10,000 years. An active volcano might be erupting or dormant.

An erupting volcano is an active volcano that is having an eruption...

A dormant volcano is an active volcano that is not erupting but supposed to erupt again.

An extinct volcano has not had an eruption for at least 10,000 years and is not expected to erupt again in a comparable time scale of the future.

The above classification is based on the frequency of eruption while the classification as a composite volcano is based on the structure of the volcano thus option C is the right answer.
