Earth Science Terminology Quiz

Study Notes

Tectonic plates are massive parts of the Earth's crust and upper mantle that constantly shift and interact.
A fault line is a weak area on the Earth's surface where these plates meet, potentially causing seismic activity.
An isthmus is a narrow strip of land connecting two larger landmasses.
The Pacific Ring of Fire is a zone around the Pacific Ocean characterized by intense volcanic activity and earthquakes.
The Circum-seismic Belt is a location marked by a high number of earthquakes, often overlapping with the Pacific Ring of Fire.
Insular refers to something surrounded by water, specifically an island.
Relative location describes a place's position in relation to its neighboring places.
Absolute location defines a place's exact position using latitude and longitude coordinates.

Latitude lines are imaginary circles that run horizontally across the Earth, indicating north and south directions.
The Equator is the 0° latitude line that divides the Earth into the Northern and Southern Hemispheres.
Longitude lines are imaginary circles that run vertically across the Earth, indicating east and west directions.
The Prime Meridian is the 0° longitude line that divides the Earth into the Eastern and Western Hemispheres.
The Tropic of Cancer is located at 23.5° N latitude.
The Tropic of Capricorn is located at 23.5° S latitude.

Southeast Asia occupies 4.43 million square kilometers, representing almost 10% of the total Asian landmass.
The region is situated south of mainland China, east of South Asia and the Bay of Bengal, and west of the Pacific Ocean.
Mainland Southeast Asia comprises Myanmar, Thailand, Cambodia, Laos, and Vietnam.
The Philippines, Indonesia, Malaysia, Brunei Darussalam, Singapore, and Timor-Leste make up the island portion of Southeast Asia.
Southeast Asian countries are located between the Tropic of Cancer and Tropic of Capricorn, and along the equatorial line.
Due to its tropical location, the region experiences warm temperatures year-round with abundant rainfall.
Southeast Asia sits at the intersection of three major continental plates: Eurasia, Indian-Australian, and Pacific.
This position makes the region part of the Pacific Ring of Fire and Circum-seismic Belt, resulting in numerous fault lines.
The Philippines Fault Zone (PFZ) extends 1,200 kilometers from northwest Luzon to southeast Mindanao.
