Geologic Activities
Whenever plates move, there is always the occurrence of what geologic activity?
Earthquake
The Philippines is formed from what type of plate boundary?
Convergent Plate Boundary
What is formed at the subduction zone?
trench
The most destructive 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
The volcanic island arc in Hawaii is formed from what?
Hotspot
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 are the products of converging oceanic plate and continental plate?
trench, volcano, mountain
True or False. S-waves can pass through solid only.
True
True or False. If the net force is zero, the velocity is constant.
False
How fast is the rate of divergence of plates?
This type of plate boundary offset spreading ridges.
Transform-Fault Boundary
A beautiful product 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
The San Andreas fault is formed from what type of plate boundary?
Transform-fault
Describe how P-waves travel in terms of direction of wave.
Perpendicular 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.
