The Philippines is formed from what type of plate boundary?
Convergent Plate Boundary
Which force always pulls downward on objects?
gravity
It is the most damaging type of wave.
Love wave
What Law of motion is shown when a rocket is launched?
3rd Law
What do you call the downward movement of slabs of rocks when two plates collide?
Subduction
What type of plates converge when trenches and volcanoes are formed?
oceanic-continental or oceanic-oceanic
A change to an objects motion is caused by ______
unbalanced forces
What type of wave is used by scientists in studying the Earth's interior?
Body waves
True or False. An object in motion will slow down if acted on by a force in the direction of motion.
False
When earthquake occur underwater and displaced a large amount of water, it will result to
tsunami
What type of plate boundary forms rift valley and oceanic ridges?
Divergent Plate Boundary
What do you call the force that always opposes motion?
Friction
Which body wave cannot pass through liquid?
S-wave
True or False. If the net force is zero, the velocity is constant.
False
How fast do paltes move in divergence?
2-20 cm/year
This type of plate boundary offset spreading ridges.
Transform-Fault Boundary
One of the beatiful products of convergence between two continental plates that lies in India, Nepal, China and Bhutan.
The Himalayas
In what medium/media can P-waves travel?
solid, liquid and gas
True or False. When an object is stationary, all of the forces acting on it are balanced.
True
It is a measure of the amount of energy released by an earthquake.
Magnitude
What are the products of convergence of plates?
Trenches, volcanoes and mountains
What is the deepest trench in the world?
Marianas trench
What isvthe difference between P-wave and S-wave in terms of propagation or direction of travel?
P-wave travels perpenpendicular while S-wave travels parallel to the direction of motion.
True or False. An object in motion will maintain its speed and direction forever unless acted upon by an equal and opposite balanced force.
True.
