Science 10 Quiz

What theory states that the Earth's lithosphere is divided into segments called plates?

• Hotspot Theory

• Plate Tectonic Theory

• Continental Drift Theory

• Seafloor Spreading Theory

The asthenosphere sublayer of the mantle is said to have some plasticity. What does this mean?

• This layer is very rigid and does not flow or move.

• The temperature of this layer is cooler than those above it.

• Organic substances compose the majority of this layer.

• Materials in this layer are partially melted and flow like a fluid.

Which plate tectonic boundary is nearest to the Philippines?

• Pacific plate - Philippine plate boundary

• Eurasian plate - Philippine plate boundary

• Philippine plate - Australian plate boundary

• Philippine plate - North American plate boundary

Which of these observations indicates that the Philippines has active volcanoes and a high frequency of earthquakes?

• The Philippines is near a big body of water.

• The country is far from a tectonic plate boundary.

• The country is near the boundary of two tectonic plates.

• The Philippines is located at the center of a tectonic plate.

What can be traced when volcanoes, earthquake epicenters, and mountain ranges are marked on the map?

• Places where archipelagos exist

• Boundaries between tectonic plates

• Countries with thin oceanic crust

• Areas prone to typhoons and storms

What can be inferred about the Philippines based on its location in relation to the tectonic plates?

• There are a lot of earthquakes and volcanism.

• There are a lot of earthquakes but minimal volcanism.

• There is very minimal earthquakes and volcanism.

• There are a lot of volcanisms but minimal earthquakes.

Which of the following is NOT a basis for identifying where the boundaries between tectonic plates lie?

• Location of volcanoes

• Distribution of earthquake epicenters

• Where mountain ranges are located

• Temperature difference on earth's surface

There are twenty-two (22) active volcanoes in the Philippines. Australia on the other hand has none. Why is this the case? It is because the Philippines ______________ while Australia ____________________.

• Is near the equator, is far from the equator

• Has a lot of earthquakes, has a lot of mountains

• Is near a plate boundary, is at the center of a tectonic plate

• Is part of a smaller plate, is part of a major tectonic plate

Australia does not have a single volcano that is active for thousands of years. What could be the reason for this?

• The size of its landmass

• Its location within the tectonic plate

• The frequency of earthquakes in the country

• Its lithosphere composition is different from others

What geologic feature/event is present on the three types of plate boundaries?

• Earthquake

• Mountains

• Rift valleys

• Volcanoes
