The 5 Themes of Geography - Definitions and Examples
Location of a place is defined according to its latitude and longitude. Latitude lines measure distances north and south of the Equator. Longitude lines measure distances east and west of the Prime Meridian. A place's absolute location is defined with latitude and longitude lines. This is its exact location.
Place Geographers study this geography theme by looking at the characteristics that distinguish one place from another place on Earth. These physical and human characteristics can include landforms, waterways, people, climate, languages, communication, and transportation.
Human/Environment Interaction Geographers study the way humans interact positively and negatively with their environments. They also study the lasting affects these interactions may have on a place. Some examples of this geography theme are damming a river, polluting the air, building highways or railroads, and even watering lawns and gardens. Human behavior such as planting trees is a positive interaction with the environment where creating landfills is a negative interaction.
Movement People are always on the move, but this theme of geography is not just about people moving from one place to another in cars and airplanes. Movement also deals with how and why people travel from one place to another. Some people travel for career, others to be close to family, and some move to escape war or religious persecution. One example of movement was pioneers heading West on the Oregon Trail in hopes of finding cheap, fertile land in Oregon.
Regions
A region is a unit on the earth's surface that has unifying characteristics such as climate or industry. These characteristics may be human, physical, or cultural. Not only do geographers study characteristics, but they also study how regions around the world may change over time.
Different types of physical regions are deserts, mountains, grasslands, and rain forests. In a city or town, there may be commercial or business regions and then residential regions. For example, in the United States, we commonly identify the South as a region. Those states that are located in the south-eastern part of the United States have similar climates and grow similar crops, in addition many people who live there have a "southern" accent. These are characteristics that help unify this area of land that is considered a region.
In case, the major ocean currents stops or slows down, the heat distribution on the Earth will be affected in the following ways:
There would be quite significant climatic changes.
It affects one of the major phenomena in the ocean , the thermohaline circulation of the ocean which is responsible for the supply of heat to the polar areas.
Heat distribution is affected in such a way that keeps the warm water of the equatorial region remains in the same region and can not delivered to the polar areas.
This phenomena results in more heat in the equatorial region and colder polar areas.
The oldest of the zircons in the study, which came from the Jack Hills of Western Australia, were around 4.3 billion years old—which means these nearly indestructible minerals formed when the Earth itself was in its infancy, only roughly 200 million years old.
Weathering is the breaking down or dissolving of rocks and minerals on Earths surface. Once a rock has been broken down, a process called erosion transports the bits of rock and minerals away. Water, acids, salt, plants, animals, and changes in temperature are all agents of weathering and erosion.
Answer: Plains occur as lowlands along the bottoms of valleys or on the doorsteps of mountains, as coastal plains, and as plateaus or uplands. ... Plains may have been formed from flowing lava, deposited by water, ice, wind, or formed by erosion by these agents from hills and mountains.
