Journey Through Time

Geography is the study of the physical features of the earth and of how human activity affects and is affected by the environment.

Some examples of physical features that geographers study are mountain ranges, state and national boundary lines, and natural landmarks like mountains and lakes.

A map is a two-dimensional drawing of the earth's surface that can show natural landmarks, like mountains and lakes, and also show man-made boundaries, like state lines or roads and trails.

<p>Geography is the study of the earth and how people interact with the earth. It is considered both a natural and social science because geographers study both the physical aspects of the earth (natural landmarks, physical features) and social phenomena like cities and human populations.</p> Signup and view all the answers

<p>GPS stands for Global Positioning System. It uses satellites to calculate the location of objects by measuring the frequency of radio signals. It helps people track their location and provides directions.</p> Signup and view all the answers

<p>GIS stands for Geographic Information System. It is a software database that collects data from GPS and other sources, allowing geographers to store and manipulate data. GIS provides a more complete view of information compared to maps or GPS.</p> Signup and view all the answers

<p>GIS can be used to enter information about rivers and population concentrations. By analyzing this data, geographers can predict who will be most affected by a chemical spill and guess where the chemicals will go based on the geography of the area.</p> Signup and view all the answers

<p>The Mercator projection is a map projection that presents north as up and south as down in all locations. It accurately represents the shape of landmasses near the equator, but it exaggerates the size of landmasses that are far away from the equator, making them appear larger than they actually are.</p> Signup and view all the answers

<p>GPS stands for Global Positioning System. It originated from attempts to track the USSR's Sputnik satellite based on shifts in its radio signal. By calculating the location of the satellite using the Doppler Effect, scientists developed a system that could accurately determine positions on Earth.</p> Signup and view all the answers

<p>GIS stands for Geographical Information System. It connects the information from GPS with other types of data. It allows people to communicate and share information that has a geographic component, whether it's in the form of images or scientific data.</p> Signup and view all the answers
