SCIENCE

Question 1

is an opening in a planet or moon’s crust through which molten rock, hot gases, and other materials erupt.

Answer 1

Volcano

Question 2

is an Intense shaking of Earth’s surface. The shaking is
caused by movements in Earth’s outermost layer.

Answer 2

earthquake

Question 3

is a series of mountains or hills ranged in a line and connected by high ground.

Answer 3

A mountain range / hill range

Question 4

, also referred to as the Circum-Pacific Belt, is a path along the Pacific Ocean characterized by active volcanoes and frequent earthquakes.

Answer 4

The Ring of Fire

Question 5

How are volcanoes, mountain ranges, and other geologic features are formed?

Answer 5

The Crust is made of solid rocks and minerals. Composed of igneous, metamorphic and sedimentary rocks.

Question 6

Two Types of Crust

Answer 6

Continental rust
Oceanic rust

Question 7

is the crust that makes up the continents. It is thicker and older than oceanic crust.

Answer 7

Continental Rust

Question 8

is the crust below the oceans. It is thinner and younger than the continental crust.

Answer 8

Oceanic crust

Question 9

is a geographical region in which very high levels of volcanic activity are present.

Answer 9

Volcanic Belt (Most volcanoes in the world are located along divergent plate boundaries. One of these boundaries is the Mid-Atlantic Ridge. and the said ridge was formed due to the separation of tectonic plates on both sides of the ocean.)

Question 10

representing Alpine-Himalayan chains of Eurasia and northern Africa and epicenters of east African fault zone. This belt represents the collision or subduction zones of continental plates.

Answer 10

Mid-Continental Belt

Question 11

is a narrow zone on the earth’s surface around which majority of earthquakes take place.

Answer 11

Earthquake Belt

Question 12

is a three-dimensional surface or zone across which there is a significant change in the velocity (speed or direction) of motion of one lithospheric plate relative to the adjacent lithospheric plate.

Answer 12

Plate boundary

Question 13

is a linear feature that exists between two tectonic plates that are moving away from. (parang kami ni ex)

Answer 13

Divergent boundary

Question 14

is an area on Earth where two or more lithospheric plates collide (parang kami ni ex pag bumalik kami)

Answer 14

Convergent Boundary

Question 15

are created when tectonic plates slide past each other horizontally along strike-slip faults or transform faults (parang charger sa outlet ko pag triny ko icharge na walang makita)

Answer 15

Transform Boundary

Question 16

is the solid, outer part of the Earth.

Answer 16

lithosphere

Question 17

A scientific theory that explains how major landforms are created as a result of Earth’s subterranean movements.

Answer 17

Plate Tectonics

Question 18

In (1915) Alfred Wegener, a German scientist, publish the theory which state that continent is moving.

Answer 18

Continental Drift Theory

[Difference Between this and plate tectonics… the former is continents moving while the latter is plate moving away.]

Question 19

A geologic process in which tectonic plates– large slabs of Earth’s lithosphere split apart from each other. In 1920 the discovery of the long chain of mountains also called mid-ocean ridges, on the ocean floor revived the continental drift theory. (By Harry Hess, an American geologist.)

Answer 19

Seafloor Spreading Theory

Question 20

was given by Arthur Holmes in the 1930s. It discussed the possibility of convection currents operating in the mantle portion These currents are generated due to radioactive elements causing thermal differences in the mantle portion.

the soul of Seafloor Spreading Theory…

Answer 20

Convectional current Theory

Question 21

Alfred Wegner. His theory was that the continents fit together like puzzle pieces. (also pangea)

Answer 21

continental fit

Question 22

types of plate margins

Answer 22

volcanoes
earthquakes
mountains

Question 23

types of mountains

Answer 23

folded
fault-block
volcanic
upwarped

Question 24

geological process, oceanic, lithosphere, recycled

Answer 24

subduction

Question 25

fossil remains

Answer 25

fossil evidence

inner core

Question 27

parts of earth?

Answer 27

asthenosphere
