Earth Science (3rd QT)

Which among the following volcanoes is classified as an active volcano?

• Cabaluyan Volcano

• Cocoro Volcano

• Kanlaon Volcano

• Urot Volcano

Volcanic eruption varies because of different factors, mainly it’s because of the characteristic of magma. What do you call the property of magma’s resistance to flow?

• Elasticity

• Fluidity

• Plasticity

• Viscosity

How are volcanoes formed?

• Due to the shaking of the ground

• Hot molten rock pushes up to the ground     

• It is the result of the spinning of the Earth

• It resulted from the movement of the ocean floor.

Temperature of the magma affects its resistance to flow. Which is TRUE in the following statement?

• As the temperature of the magma increases its viscosity increases

• As the temperature of the magma increases its viscosity decreases

• As the temperature of the magma decreases its viscosity decreases,

• As the temperature of the magma decreases its viscosity remains the same.

It is characterized by gas-driven explosion that propels magma and tephra. It happens when think and viscous lava clogs the vent, preventing gases from escaping, causing pressure to build up.

• Calm to violent type of volcanic eruption        

• Explosive type of volcanic eruption

• Effusive type of volcanic eruption.

• None of the answers is correct.

Which of the following is the CORRECT statement about Geothermal energy?

• Geothermal energy is the heat energy present in outer space.

• Geothermal energy is the heat energy present on the surface of the ocean.

• Geothermal energy is the heat energy present in the interior of the Earth.

• Geothermal energy is the heat energy present on the surface of the Earth.

It is a type of machine where the wheels are driven by a fluid(gas/liquid) to produce work. It converts steam into mechanical energy.

• Transformer

• Generator

• Turbine

• Condenser

How geothermal energy turns into electrical energy?

• When steam is delivered to the generator, it powers the turbine that produces electricity

• When steam is delivered to the turbine, it powers the condensers that produces electricity

• When steam is delivered to the turbine, it powers the generator that produces electricity.

• When steam is delivered to the generator, it powers the condensers that produces electricity

Maria's house is located up on a hill and has a colder climate. It is located near the equator. What will most likely affect the climate of the place?

• Altitude

• Latitude         

• Ocean Currents

• Topography

What is the primary cause of ocean surface currents?

• Migrating Fish

• Rain

• Ships

• Wind
