Quiz 1

Question 1

The term “tectonic” (from the Latin
word tectonicus or Greek
word tektonikos Means?

Answer 1

To Build

Question 2

Crust and the upper part of the mantle

Answer 2

Lithosphere

Question 3

• a ductile layer under the solid lithosphere.

• composed of rocks that are partly molten due to high temperature and pressure under the lithosphere.

Answer 3

Asthenosphere

Question 4

A geologist and Navy submarine commander during WW2, part of his mission is to study the deepest part of the ocean floor

Answer 4

Harry hest

Question 5

Thinnest and outermost layer of the earth

Answer 5

Crust

Question 6

Types of crust

Answer 6

Continental and Oceanic

Question 7

A German polar researcher, geophysicist, and meteorologist
Also known as the father of plate tectonics theory

Answer 7

Alfred Wegner

Question 8

• The strength of earthquakes can range from shallow to destructive.

• These earthquakes can be due to collisions, rifting, or slipping between or among the plates.

• Around 90% of eathquakes are felt along the plate margins.

• Earthquakes felt in areas within the plate are mostly due to stress buildup in some continental rifting zones or due to the transfer of energy from other regions.

Answer 8

Earthquake distribution

Question 9

• In determining the epicenter of an earthquake, the difference in arrival time between the primary waves and the secondary waves which comes from a seismograph wave in seismic recording stations.

• Triangulation method is used to find the epicenter.

Answer 9

Seismic waves

Question 10

Types of plate boundaries

Answer 10

Convergent: Plates move towards each other.

Divergent: Plates move away from each other.

Transform: Plates slide past each other.

Question 11

places where tectonic plates collide or come together. When two plates meet, their interactions can result in various geological phenomena.

Convergent boundaries contribute to the formation of mountains, volcanic activity, and earthquakes.

Answer 11

Convergent Boundaries

Question 12

plates move away from each other. This movement results in the creation of new crust as magma rises from the mantle, solidifies, and forms new oceanic crust.

This boundaries are responsible for the continuous reshaping and formation of Earth’s crust.

Answer 12

Divergent Boundaries

Question 13

occurs when two plates slide past each other horizontally. The movement along these boundaries can cause earthquakes, as the plates grind against each other.

This boundaries redistribute stress and accommodate the movement between neighboring plates.

Answer 13

Transform Boundaries

Question 14

• Distribution of volcanoes is mostly found along the plate margins, which can be in an either destructive or constructive boundary.

• Volcanoes are also found in areas where there is subduction of plates.

Answer 14

Volcanic Distribution

Question 15

• Mountains have been formed due to the movement of plates, either apart or toward each other.

• Some are formed underwater or on the seabed, whereas others are formed on top of the continental crust.

Answer 15

Mountain Ranges

Question 16

The solid and fluid layers of Earth, which are the lithosphere and the asthenosphere, respectively.

• Convection current is the driving mechanism of plate movement.

• Due to te differences in the densities of the two crustal features of the lithosphere, when the internal driving force from Earth causes the surface to move, it results in different geologic phenomena such as earthquake and volcanic activities.

Answer 16

Plate tectonic theory

Question 17

• also known as plate boundaries have three types: convergent, divergent, and transform.

Answer 17

Plate margins

Question 18

•collision between oceanic and continental crust.

•oceanic crust sinks down the continental rust and goes back to the mantle called subduction.

• Trenches are also formed by the intersection of the oceanic and continental crust.

Answer 18

Oceanic Continental convergence

Question 19

• collision between two oceanic plates.

• It causes one plate to subduct from the other.

• both oceanic crust have the same density, the one that subducts is the older plate.

Answer 19

Oceanic oceanic Convergence

Question 20

•Two continental crust move toward one another.

•Formation of mountains

• Crustal plates meet up occurs, one crust descends to the other continental crust but not toward the mantle.

Answer 20

Continental continental Convergence

Question 21

the origin at which earthquake occurs.

Answer 21

Hypocenter/focus

Question 22

the point directly above the focus on the surface.

Answer 22

Epicenter

Question 23

Bodywave and surface wave

Answer 23

Seismic waves

Question 24

Are in the form of primary and secondary waves.

Answer 24

Body waves

Question 25

travel through the interior of Earth and through solid and fluid materials. They travel faster than secondary waves.

their velocities varies depending on the location and material in which they move.

their motion is longitudinal, which vibrates along with the direction Particle Motion of its motion.

Answer 25

Primary wave/ p waves

Question 26

travel through solid materials only within the interior of the Earth.

velocity is less than that of P-waves.

Their vibrations are perpendicular to the direction of the motion of the waves.

Answer 26

Secondary wave/ s wave

Question 27

• occurs on the surface of the lithosphere.

• can be a love wave or Rayleigh wave.

Answer 27

Surface wave

Question 28

sweep the surface in a side-to-side movement.

transverse wave

Answer 28

Love wave

Question 29

shakes the ground in an up- and-down movement.

Answer 29

Rayleigh wave

Question 30

an instrument that detects and measure seismic waves.

Answer 30

Seismo graph

Question 31

• internal part of seismograph.

• works as a pendulum that swings back and forth which is attached to a barrel that rotates and makes prints of the ground shaking.

Answer 31

Seismic meter

Question 32

• is the most common scale for the magnitude of an earthquake.

• also called local magnitude.

logarithmic scale of the wave amplitude of an earthquake.

Answer 32

Richter scale
