CONTINENTAL DRIFT AND PLATE TECTONIC

Question 1

-This theory states that all the continents were once one large landmass that broke down apart, and
where the pieces moved slowly to their current locations.

Answer 1

CONTINENTAL DRIFT THEORY

Question 2

a German meteorologist (1880-1830). He believes that the continents were once part of a large landmass called PANGEA that drifted apart or away from each other. During the Jurassic period, the Pangea began to split into two smaller supercontinents called LAURASIA and
GONDWANALAND.

Question 4

a large landmass that drifted apart or away from each other.

Answer 4

PANGEA

Question 5

Pangea began to split into two smaller supercontinents called

Answer 5

LAURASIA and
GONDWANALAND.

Question 6

The northern part of the supercontinent comprising the Europe, North America,
and Asia.

Answer 6

LAURASIA

Question 7

The southern part of the supercontinent comprising the Africa, Antarctica,
Australia, South America.

Answer 7

GONDWANALAND

Question 8

EVIDENCES

Answer 8

1. Topographic Evidence
2. Fossil Evidence
3. Rock Evidence
4. Paleoclimatic Evidence

Question 9

Geologic process that continually adds new material to the ocean floor while pushing old rocks away from the mid ocean ridge.

Answer 9

SEA FLOOR SPREADING

Question 10

This theory was proposed in 1960 by Harry Hammond Hess (1906-1969), a professor of geology at Princeton University (USA). He study the ocean floor through using sonar.

Answer 10

SEA FLOOR SPREADING THEORY

Question 11

a sounding gear helpful for exploring and mapping the ocean floor with the use of sound waves.

Answer 11

SONAR

Question 12

A theory that combines the idea of continental drift and sea floor spreading.
- According to this theory, the lithosphere is broken up into section or pieces that move on top of the liquid mantle (asthenosphere).

Answer 12

PLATE TECTONIC THEORY

Question 13

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

Answer 13

Plate tectonics

Question 14

PLATE BOUNDARY

Answer 14

✓ Areas in which tectonic plate meets
✓ All tectonic plates share boundaries with other tectonic plates
✓ The type of boundary depends on how the tectonic plates move relative to one another.

Question 15

Type of Plate Boundaries

Answer 15

1. DIVERGENT PLATE BOUNDARIES
2. CONVERGENT PLATE BOUNDARIES
3. TRANSFORM PLATE BOUNDARIES

Question 16

the two plates move away from each other. Sea floor spreading happens.

Answer 16

DIVERGENT PLATE BOUNDARIES

Question 17

The two plates move toward each other.

Answer 17

CONVERGENT PLATE BOUNDARIES

Question 18

two plates slide or grind past each other without diverging or converging. Best example of
this plate is the San Andreas fault which is bounded by the North American plate and the
Pacific plate.

Answer 18

TRANSFORM PLATE BOUNDARIES
