PLATE TECTONICS BASICS
This theory explains that Earth's lithosphere is divided into large moving plates.
Plate Tectonics
This layer allows tectonic plates to move.
Asthenosphere
These are the three types of plate boundaries.
Convergent, Divergent, and Transform boundaries
The Philippines is located where several tectonic plates meet. This location is called a ______.
Triple-plate junction
The day-to-day condition of the atmosphere is called this.
Weather
Millions of years ago, all continents were joined together in one supercontinent
Pangea
Hot materials rise while cooler materials sink, creating this movement inside the mantle.
Convection currents
Two plates move toward each other in this type of boundary.
Convergent Plate Boundary
Name the three tectonic plates interacting beneath the Philippines.
Eurasian Plate, Philippine Sea Plate, and Indo-Australian Plate
The average weather condition of a place over a long period is called this.
Climate
This scientist proposed the Continental Drift Theory
Alfred Wegener
At mid-ocean ridges, newly formed crust pushes older crust away. This process is called ______.
Ridge Push
This boundary happens when plates slide past each other and may cause earthquakes.
Transform Plate Boundary
This active fault runs across the Philippines and causes major earthquakes.
Philippine Fault
This factor tells how hot or cold the air is.
Temperature
Scientists used this evidence, including matching coastlines and fossils, to support that continents were once connected.
Evidence of continental drift
A dense oceanic plate sinks into the mantle and pulls the rest of the plate downward.
Slab pull
A place where one plate sinks beneath another plate is called this.
Subduction Zone
Why does the Philippines experience frequent earthquakes and volcanic activity?
Because it is located near active plate boundaries.
A farmer checks this before planting because it affects rainfall and growing conditions.
Weather and Climate Factors
A student says: "Continents look like puzzle pieces because they were randomly formed that way." Explain why this statement is incorrect.
Continents fit together because they were once connected and moved due to plate tectonics.
Why do scientists say heat and gravity work together in plate movement?
Heat creates convection currents while gravity pulls dense plates downward.
A volcano, mountain range, and deep ocean trench are discovered near each other. What plate interaction most likely happened?
A convergent boundary with subduction occurred.
Scientists predict that after millions of years, the Philippines may reconnect with mainland Asia. What process causes this?
Continuous movement of tectonic plates.
Two cities are located at the same latitude. One is near the ocean while the other is inland. Why might their climates be different?
Bodies of water can moderate temperature and influence climate.
