There are some instances where lava does not escape from the crate and flows along the chamber inside the crust and harden, it is then called?

A

Intrusive volcanism

23
Q

In a volcanic eruption, the flow of magma or lava is affected by _________________ and __________________.

A

temperature, composition

24
Q

The magma’s ability to flow.

A

Viscosity

25
Q

Volcanoes that arise from the excretion of magma to the mantle.

A

Hotspots

26
Q

2 types of lava flow

A
  • aa (ah-ah)
  • pahoehoe (pah-hoy-hoy)
27
Q

The process of mountain building.

A

orogeny

28
Q

A large surface feature that rises above its relative.

A

Mountain

29
Q

Series of mountain chains

A

mountain ranges

30
Q

3 types of mountain building

A
  • Andean -type
  • island arc
  • continental volcanic arc
31
Q

A mountain building whose major features are deep-ocean trenches and volcanic arcs.

A

Island arc

32
Q

It is caused by the compression of the crust above the other in the collision process.

A

Continental volcanic arc

33
Q

It occurs when two oceanic plates converge, and as the leading plate subducts from the other, the plate piles up, forming volcanic island arcs that consist of igneous and metamorphic rocks.

A

Island arc

34
Q

This type of mountain building occurs along continental plate boundaries.

A

Andean-type

35
Q

The most visible effect of orogenesis.

A

The faulting and folding of the lithospheric plate

36
Q

It happens when a force compresses the crust, causing the crust to bend from its sides.

A

Folding

37
Q

The peak of any folded rock layer.

A

Anticline

38
Q

The lowest point of the fold.

A

Syncline

39
Q

It is characterized by a sharp-peaked anticline fold.

A

tight fold

40
Q

The bending or warping of folding rock layers.

A

Overfold

41
Q

A type of fold that is a result of too much bending that no vertical regions can be seen.

A

Recumbent fold

42
Q

A fold that has overturned, causing rock layers to be fractured.

A

Nappe

43
Q

It is defined as the slope or inclination of any geological surface.

A

Dip

44
Q

Any horizontal line that is drawn on the sloping surface.

A

Strike

45
Q

Other scales that express the magnitude of earthquakes.

A
  • surface-wave magnitude
  • body-wave magnitude
  • moment magnitude
46
Q

The inactive volcano is the one…

A

farther away from the current active volcano.

47
Q

The most active volcano is the one…

A

directly above the mantle plume where the magma is rising.

48
Q

It can be considered an agent of change.

A

Volcanic eruptions

49
Q

The rock that falls under the fault.

A

foot wall

49
Q

It is characterized by the movement of the hanging wall.

A

Dip-slip fault

50
Q

Any rock that falls above the fault line.

A

Hanging wall

51
Q

A dip-slip fault whose hanging wall falls down the surface of the fault.

A

Normal fault
