Land-Forms Quiz

What happens when two plates push upward against each other ?

• They form a mountain

• They form a trench

• they bounce back against each other

• they don't move

Answer explanation

When two tectonic plates push upward against each other, they can create mountains due to the intense pressure and folding of the Earth's crust. This process is known as orogeny, leading to the formation of mountain ranges.

The liquid inside a volcano is (a)  

Answer explanation

The liquid inside a volcano is called magma. When magma erupts to the surface, it is referred to as lava. Therefore, the correct answer is magma.

How many volcanoes are in the ring of fire ?

• 236

• 450

• more than 450

• 156

Answer explanation

The Ring of Fire is a major area in the Pacific Ocean basin known for its high volcanic activity, with estimates of over 450 volcanoes. Therefore, the correct answer is 'more than 450'.

(a)   Has the most volcanoes in the world

The safest place to build a house is .

• A Mountain-side

• A grassy plain

• The middle of the road

• On a Volcano

Answer explanation

A grassy plain is the safest place to build a house because it is typically flat and free from natural hazards like landslides or volcanic activity, unlike a mountain-side or a volcano, which pose significant risks.

Which of the following is a primary cause of earthquakes?

• Tectonic Plates Moving

• Shaking Magma

• Friction moving the plates against each other

Answer explanation

Friction between tectonic plates causes them to stick and build up stress. When this stress is released, it results in an earthquake. Thus, friction moving the plates against each other is a primary cause of earthquakes.

Which layer of the Earth is responsible for tectonic plate movement?

• Atmosphere

• Crust

• Core

• Mantle

Answer explanation

The mantle is the layer of the Earth that lies beneath the crust and is responsible for the movement of tectonic plates due to its semi-fluid properties, allowing convection currents to drive plate tectonics.

What is the primary factor that causes volcanic eruptions?

• Solar flares

• Pressure from magma

• Ocean currents

• Wind patterns

Answer explanation

The primary factor causing volcanic eruptions is pressure from magma. As magma rises to the surface, it builds up pressure in the Earth's crust, leading to eruptions when the pressure exceeds the strength of the surrounding rock.

Which type of boundary is most likely to cause earthquakes?

• Convergent boundary

• Divergent boundary

• Transform boundary

• Static boundary

Answer explanation

Transform boundaries are where tectonic plates slide past each other, causing friction and stress that can lead to earthquakes. While convergent boundaries also cause earthquakes, transform boundaries are particularly known for their frequent seismic activity.

What is the most powerful type of storm ?

(a)  

Answer explanation

Hurricanes are the most powerful type of storm, characterized by strong winds and heavy rainfall. They can cause significant damage and are classified by their wind speeds, making them the most intense storms on Earth.
