Study Notes

Globe, Latitude, and Longitude

A globe represents the Earth in three-dimensional form.
The Prime Meridian separates the globe into Eastern and Western Hemispheres.
Latitude and longitude create a coordinate grid for pinpointing locations on Earth’s surface.
The Prime Meridian runs through the Royal Observatory in Greenwich, England.
There are 360 degrees of longitude globally, facilitating time measurement.

Geography Concepts

Geoid defines the Earth's shape—an irregular sphere.
A globe accurately depicts landmasses and water bodies in proportion.
The Equator is an imaginary line that divides the Earth into Northern and Southern Hemispheres.
Canada is an example of a country with multiple time zones due to its vast size.
The Torrid Zone is recognized as the hottest temperature zone on Earth.

International Date Line

The Earth rotates around an imaginary line called the axis.
Latitudes measure north or south distance from the Equator; important for navigation.
Longitudes extend vertically from the North Pole to the South Pole, facilitating east-west measurements.
Latitude and longitude lines intersect to create a grid system used on maps.

Time Zones and Standard Time

The International Date Line is where a calendar day shifts, observing a 24-hour cycle.
Standard time balances time across various regions, minimizing confusion caused by multiple local times.
Countries with significant east-west distance need several time zones to maintain local time precision.
The terms ante meridiem (a.m.) and post meridiem (p.m.) stem from Latin phrases indicating times before and after noon, respectively.

Locating Places and Climate Prediction

Maps utilize latitude and longitude for identifying specific locations, with 180 degrees of latitude and 360 degrees of longitude.
Every degree of latitude and longitude is divided into minutes and seconds for precise navigation.
Climate zones, determined by latitude:
- Torrid Zone (near the Equator) is generally hot.
- Temperate Zone experiences mild climates.
- Frigid Zone (near the poles) is very cold.
Local time relies on the position of the overhead Sun, signaling noon for each respective latitude.

Effects of Earth's Movement on Time and Temperature

Traveling west to east results in gaining time due to the Earth’s eastward rotation.
Moving away from the Equator leads to temperature drops as the Sun’s rays hit at slanted angles, distributing heat over larger areas.
