volcanoes and climate

Qliah is studying about the volcanoes in the country. Which of the following is classified as active volcano in the Philippines?

• a. Pulong

• Banahaw, Pinatubo and Mayon Volcano

• Banahaw and Pinatubo

• Pulong and Banahaw

Which of the following is a characteristic of a volcano?

I. Triangle shaped                                            II. Emits hot rocks

III. It has crater                                                  IV. It gives off hot gases

• I only

• I and II

• II and III

• II, III and IV

Vincent is a geologist and detect many small or minimal earthquakes in the area near a volcano, what they can infer about the volcano?

• It is extinct

• It shows a probable signs of eruption.

• It is dormant

• It is a good source of geothermal energy

Jyroh is studying the volcanoes eruptive style, which of the following conclusion about the study is correct?

• The amount of dissolved gases a volcano contains do not affects its eruptive style.

• Pressure and the amount of gases a volcano contains affects the eruptive style of a volcano.

• The volcanoes chemical composition and magmas temperature is related to it eruptive style.

• The amount of dissolved gases a volcano contains, chemical composition and magmas temperature affects the volcanoes eruptive style

Which type of volcanoes have broad bases and steep sides, usually have a large crater at the top and are formed by alternating layers of magma and ash?

• a. caldera

• composite volcanoes

• shield volcanoes

• cinder cone volcanoes

Why is the volcano considered as “window” into the Earth?

• through the opening the volcano, scientists can travel into the Earth’s interior

• scientific research equipment lowered many kilometers through volcanic openings which provided valuable data about the outer core.

• lava can lead us into studying the Earth farther

• materials ejected by the volcano can give scientists clues about the Earth’s interior

These Volanoes are not expected to erupt in the future.

Volcanoes that have recently erupted are known as:

• Extinct Volcano
• Dormant Volcano
• Active Volcano
• What's a volcano?

Shield volcanoes have:

• gently sloping sides
• a steep cone shape
• moderately sized sides
• long cracks along plate boundaries

Explosive eruption that hurls ash, gases, cinders, and bombs from the main vent.

• Volcano bomb
• Geyser
• Geothermal energy
• Pyroclastic flow
