Grade 10 4th Quarter Review

These flashcards cover key concepts related to geological mechanisms, including plate tectonics, volcanic activity, and historical geology as covered in the lecture.

What are students not allowed to use during the quiz?

Browsing notes or using mobile phones.

What is the longest mountain range in the Philippines?

Sierra Madre Mountain Range.

What is it called when many closely spaced mountains cover a portion of the Earth?

Mountain Ranges.

What high landform opens downward to a chamber of molten rock?

Volcano.

What vibration occurs due to rapid release of energy in the Earth's crust?

Earthquake.

What makes up the lithosphere?

Continental and Oceanic Crust.

Which Philippine volcano is noted for its violent eruption in 1991?

Mount Pinatubo.

What is the safest place in the Philippines regarding geologic disasters?

Palawan.

What is known as the ‘Ring of Fire’?

A region around the rim of the Pacific Ocean where many volcanic eruptions and earthquakes occur.

Which theory describes the continuous movement of tectonic plates?

Plate Tectonics.

What is the basis for dividing Earth's lithosphere into plates?

The occurrence of earthquakes, volcanism, and mountain formation.

What type of plate boundary exists when plates are coming together?

Convergent.

How are mountain ranges related to volcanoes and earthquake epicenters?

Mountain ranges are found in places where volcanoes and/or earthquake epicenters are also situated.

What defines a divergent plate boundary?

A boundary between two plates that are moving apart.

Where are the youngest rocks located on the ocean floor?

Mid-ocean Ridges.

How do the plates move in a transform fault boundary?

They slide past each other.

What is the most abundant element in the Earth's crust?

Oxygen.

What is a special feature of the upper mantle?

It contains the asthenosphere which facilitates the movement of lithospheric plates.

What materials make up the Earth's inner core?

Mostly iron and nickel.

What is a possible cause of plate movement that involves heated mantle and density changes?

Mantle Convection.

What theory states that a supercontinent once existed and broke apart?

Continental Drift Theory.

What two smaller supercontinents did Pangaea break into?

Laurasia and Gondwana.

What is the name of the ancient plant fossil related to the supercontinent theory?

Glossopteris.
