A

Sierra Madre

43
Q

A theory that suggests that Earth’s Crust is made up of plates that interact in various ways, thus producing earthquakes, mountains, volcanoes, and other geologic features.

A

PLATE TECTONICS

44
Q

TRUE OR FALSE?
iT IS SUGGEST THAT PLATES ARE MOVING AND LEAD TO THE CHANGE IN THE SURFACE

A

TRUEE

45
Q

A German Meteorologist, proposed a theory “The Continental Drift” that about 200 million years ago, the continents were once one large landmass.

A

ALFRED WEGENER (1912)

46
Q

What did Alfred Wegener called this landmass?

A

Pangaea

47
Q

“Pangaea’ a Greek word means?

A

“All Earth”.

48
Q

A theory that states that the Continents are moving

A

Continental Drift Theory

49
Q

Was Wegener Theory that the continents were once joined together was accepted?

A

NO
(It was not accepted and he was not able to explain how this drifting took place)

50
Q

During WHAT YEAR, new techniques and modern gadgets enabled scientists to make better observations and gather new information about the ocean floor.

A

Q

With the use of __________, scientists had a clearer view of the ocean floor.
(They have discovered underwater features deep within the ocean.)

53
Q

He stated that oceans have tectonic Activity

A

69
Q

The movement of plates is influenced by two types of forces

A

Driving forces
Resisting forces

70
Q

Push tectonic plates forward or toward one another or pull them apart

A

Driving Forces

71
Q

Core rising toward the mantle

A

Mantle Convection

72
Q

drive the plates away from one another, this heat dissipates and creates a current due to the difference in temperature.

A

Convection Current

73
Q

-OPPOSITE OF MANTLE DRAG
-takes place when a subducting slab sinks into the hot mantle because of a difference in temperature
- The rest of the plate to which the slab is attached to is pulled in as well.

A

Slab pull

74
Q

occurs two colliding plates, one subducting underneath the other, whereby convection currents in the upper mantle suck both plates down.

A

Slab suction

75
Q

when the lithosphere is pushed up by the asthenosphere because of convection currents from the mantle.
Gravity pushes the plate down the ridge and a new crust is formed.

A

Ridge Push

76
Q

Act against the driving forces of plate tectonics

A

Resisting forces

77
Q

FORCE that resists all the forces associated with plate movement in subduction zones.
- Plates collide of a plate boundary

A

SLAB RESISTANCE

78
Q

occurs when a heavy plate is pulled into the mantle but resists subduction because of friction.

A

Collisional Resistance

79
Q

-This force opposes the slab pull

A

Collisional Resistance

80
Q

is the frictional force due to the opposing MOVEMENT OF PLATES MOVING PAST ONE ANOTHER BETWEEN TWO SPREADING CENTERS.

-“ZONE OF ATTRACTION”

A

Transform fault resistance

81
Q

Resist movement of lithospheric or in atmospheric plates

A

drag force

82
Q

WHAT ARE THE 4 DRIVING FORCES?

A

Mantle convection
Slab pull
slab suction
Ridge push

83
Q

WHAT ARE THE 4 RESISTING FORCES?

A

slab resistance
collisional resistance
transform fault resistance
drag force

84
