Which theme considers latitude and longitude

People make changes to the places. People build roads, bridges, cities, and grow food. The thoughts people have about a place come from their experiences. How people describe a place tells you how they think.

It tells you what is important to them. Think about the human and physical features of your hometown. How do they shape your life? The Eiffel Tower is a landmark in Paris. Human-environment interaction answers the question, How do people and the environment affect each other?

This theme looks at how people interact with their environments. People use their environment in different ways. In dry areas, people might build dams to collect large amounts of water. Then people can use the water during dry periods when there is no rain. In wet areas, people might use boats to travel from place to place. Some changes people make can cause problems. Pollution is a problem. Sometimes, weather can harm people.

Some areas have floods, mudslides, or wildfires. In Southeast Asia, farmers use water buffalo to plow the land for rice fields.

Movement answers the question, How do people, goods, and ideas get from one place to another? Movement means change. The study of movement shows how people and goods travel import and export. It also explains how people bring new ideas to other areas of the world. Can you think of ideas that moved from other areas? Thus, human-environment interaction needs special emphasis and has been classified as one of the five themes of geography. It involves three distinct aspects: dependency, adaptation, and modification.

Dependency explores the ways in which humans are dependent on nature for a living. For example, in India , farmers across the country wait for the monsoons to arrive for the successful growth of their rain-fed crops.

If monsoons are late, or the rains are insufficient, droughts and food crises might create havoc in the highly populated country. Adaptation relates to how humans modify themselves, their lifestyles and their behavior to live in a new environment with new challenges. The different types of clothing invented by humans is one of the finest examples of how humans adapted to varying environmental conditions since the early days. While people in the cold countries adorned wool and fur clothing, those in the warmer countries adhered to cotton.

Humans built dams to water their fields in the dry season. They invented air coolers and air heaters to modify the air temperatures of the environment they inhabited.

Humans also tamed wild animals for their exploitation, converted large tracts of dense forests to human-dominated settlements, and developed automobiles and airplanes that shortened distances between places. It is this final aspect of the human-environment interaction, the modification of the environment, that has also created huge problems on the Earth today. Global warming and climate change , mass extinctions of wild species, high levels of environmental pollution, etc.

The Earth is full of movement and on a human-dominated planet, movement primarily refers to the translocation of human beings, their goods, and their ideas from one end of the planet to another. Thus, the theme of movement becomes an important part of geographical studies.

Movement deals with studies of population immigration, emigration, and distribution in the countries of the world. It is this physical movement of people that has allowed the human race to inhabit all the continents of the world, explore the depths of the oceans and land on the moon. Another aspect of movement is the transport of goods from one place on the Earth to another. This theme considers how humans adapt to and modify the environment.

Humans shape the landscape through their interaction with the land, which has both positive and negative effects on the environment. As an example of the human-environment interaction , think about how people living in cold climates have often mined coal or drilled for natural gas in order to heat their homes.

Another example would be the massive landfill projects in Boston conducted in the 18th and 19th centuries to expand habitable areas and improve transportation. Humans move—a lot! In addition, ideas, fads, goods, resources, and communication all travel distances.

This theme studies movement and migration across the planet. The emigration of Syrians during war, the flow of water in the Gulf Stream, and the expansion of cell phone reception around the planet are all examples of movement.

Regions divide the world into manageable units for geographic study. Regions have some sort of characteristic that unifies the area and can be formal, functional, or vernacular.
