Test: Geographic Grid Latitudes and Longitudes - SSS 1 MCQ

The Torrid Zone is located between the Tropic of Cancer (23.5° N) and the Tropic of Capricorn (23.5° S). This zone is characterized by the hottest temperatures due to direct sunlight throughout the year.

Crossing the International Date Line from east to west results in gaining a day. The IDL serves as the boundary for changing dates and is located near 180° longitude.

The Equator is the longest latitude line at 0° latitude. It divides the Earth into the Northern and Southern Hemispheres and is a reference point for measuring latitude. Other latitude lines, known as parallels, decrease in length as they approach the poles.

The distance between meridians decreases as one moves toward the poles. At the poles, meridians converge and the distance becomes zero, which is important for understanding geographic navigation.

The distance between two consecutive latitude lines is about 111 km (or 69 miles). This measurement is crucial for geographic navigation and helps in calculating distances on Earth.

The Geographic Grid is a system of lines that helps in locating places accurately. It consists of latitude and longitude lines, which serve as reference points for navigation and mapping. This grid system is essential for understanding geographical relationships and positioning on Earth.

The Prime Meridian is not a latitude line; it is a longitude line at 0° that serves as the reference for measuring east-west positions. The Tropic of Cancer, Tropic of Capricorn, and Arctic Circle are all significant latitude lines.

The Earth rotates 360° in 24 hours, which means it covers 15° of longitude every hour. This relationship is crucial for understanding time zones and calculating local times based on longitudinal positions.

There are 360 meridians around the Earth, with 180 to the east and 180 to the west of the Prime Meridian. These meridians help in determining geographic locations and are crucial for navigation.

A great circle represents the shortest distance between two points on a sphere, such as the Earth. Great circles, including the Equator and pairs of opposite meridians, are essential for navigation and route planning.

The North Frigid Zone extends from 66.5° N to the North Pole at 90° N. This zone is characterized by extremely cold temperatures and harsh climatic conditions, making it inhospitable for most life forms.

The Great Circle Distance Formula is used to calculate the shortest distance between two points on the Earth's surface. This is crucial for navigation, especially for aircraft and ships, to optimize travel routes.

The main function of latitude lines is to measure distances north or south of the Equator. These lines help in identifying locations and understanding the Earth's climate zones based on latitude.

Lines of longitude, also known as meridians, run from pole to pole. They help determine time and location on the Earth’s surface, unlike latitude lines, which are parallel to the Equator and measure distance north or south.

The world is divided into 24 time zones, each spanning 15° of longitude. This division is based on the Earth's rotation and helps standardize time across different regions.

Latitude lines are spaced 1° apart, allowing for precise measurement of distances north or south of the Equator. This spacing helps in various geographic calculations and navigation.

The Prime Meridian is significant as it serves as the reference point for measuring longitude at 0°. It divides the Earth into Eastern and Western Hemispheres and is used as the basis for time zones, specifically Greenwich Mean Time (GMT).

Local Time is determined based on the Sun's position overhead at noon in a specific place. This type of time can vary significantly based on longitude, as the Earth rotates.

The Temperate Zone, which includes both the North and South Temperate Zones, experiences moderate temperatures. This zone is located between the Tropics and the Polar Regions, allowing for diverse climates.

Standard time refers to the uniform time used across a country, which is typically based on the local time of its central meridian. This helps maintain consistency in timekeeping, especially in larger countries with multiple time zones.
