Unit 1, part 4, the study of geography, earth
1) The ancient Greeks knew as early as the 3rd century BC that the Earth was round. Eratosthenes calculated the circumference of the Earth with remarkable accuracy in the 3rd century BC.
2) Eratosthenes was the first person to use the terms "geography" and "latitude and longitude" to describe locations on Earth. He invented the concept of measuring locations using lines of latitude and longitude.
3) Time zones were established in 1884 to standardize time based on lines of longitude, in order to account for the fact that the sun reaches different places on Earth at different times. There are 24 global time zones, each approximately 15 degrees of longitude wide.
Map
Maps are used to represent the Earth's surface and show the relationship between locations. A map depicts features like distance, direction, and size on a flat surface that can be easily transported. Different types of maps serve various purposes. Topographic maps represent 3D terrain with contour lines and are used by hikers and engineers. Geologic maps show rock formations and are used by geologists. Biogeographic maps illustrate where animals and plants live and are used by scientists to understand species ranges. Environmental maps depict features like forests, climate, and oceans used by meteorologists and planners.

World geography intro powerpoint
Geography is the study of Earth and the relationship between people and their environments. Geographers analyze locations using five themes: location, place, human-environment interaction, movement, and regions. They study physical features like landforms and oceans as well as human aspects such as population and land use. Maps are important tools that help geographers represent Earth's spherical shape on a flat surface, despite some distortion, using techniques like projections and grids. Globes are also used to depict Earth accurately as a round object.

Physical Geography Lecture 03 - Maps 100316
Maps are a geographer's tool for representing the three-dimensional real world in two dimensions. While flat maps necessarily distort features like shape, size or direction to varying degrees, cartographers use map projections to minimize these distortions. Common projections include cylindrical, azimuthal, conic, and pseudocylindrical projections. Topographic maps produced by the USGS precisely represent land elevations and relief using contour lines. However, what and what is not represented on maps can reflect biases and influence how we perceive the world.
5 themes intro
Geography is the study of the physical, human, and biological systems of Earth. Geographers examine the relationship between humans and their environments. They use five themes - location, place, human-environment interaction, movement, and regions - to analyze and organize information about Earth. Geography mixes both natural and human aspects to understand our world.

Space By Matthew Maguire
This document introduces the vast unknowns of space and the universe. It notes that while human life began on Earth, humans had little initial understanding of what existed beyond the planet. Recent technological advances have allowed humanity to gain more information and images of space. The document compares the relative sizes of planets and the sun to demonstrate how small Earth appears at different scales. It suggests continuing space exploration is important to learn if other life exists in the universe and to prepare for potential threats. Some scientists now believe parallel universes may exist, with the possibility of alternate versions of Earth, countries, and even people. The document encourages further discovery of the universe.

Nicolaus Copernicus made the groundbreaking discovery in 1514 that the Earth and other planets revolve around the Sun, contradicting the prevailing view that the Earth was the center of the universe. He used science and mathematics to explain the orbits of each planet and how long it takes for them to revolve. This discovery was vitally important because it allowed for an accurate solar system model and calendar, which we now rely on for predicting seasons, sending spacecraft, and tracking the passage of time.
5 themes and map skills
The document discusses the 5 themes of geography: location, place, interaction, movement, and region. It then provides examples to illustrate each theme. For example, it explains that interaction looks at how humans and the environment affect each other, such as how human-caused global warming is changing the planet. The document also covers map skills, different types of maps, and how to read and interpret maps.
