Physical geography

We study the natural world.

One part of this is physical geography. It looks at how our world works. We study the air and the water.

We look at the shape of the land. We study how rivers move. We also look at the ice.

Some people study the soil. They look at where plants and animals live. This helps us learn about nature.

It is fun to see how things change. The world is full of wonder!

Physical geography is a way to study our natural world.

It looks at the patterns in nature. This includes the air, the water, and the land.

One part of this study is geomorphology. This field looks at how the Earth's surface is shaped. It looks at how land changes over time.

Scientists also study water in a field called hydrology. They look at rivers, lakes, and even underground water.

They study the way water moves across the land.

Other experts study the ice. This is called glaciology. They look at big ice sheets and small glaciers. Some people study the climate. They look at weather over a long time. Others study where plants and animals live. This is called biogeography. This field helps us see how life spreads across the Earth. Physical geography helps us understand how all these parts work together.

Physical geography is a major branch of science.

It focuses on the natural world around us. This study looks at patterns in the air, water, and land. Scientists call these parts the atmosphere, hydrosphere, biosphere, and geosphere. It is different from human geography. Human geography looks at the places people build. Technical geography looks at tools for spatial information. These different branches often overlap and work together.

Many special fields help us understand these natural patterns. Geomorphology studies how the Earth's surface gets its shape.

It looks at how land changed in the past and how it changes now. Hydrology is the study of water moving on the land.

This includes water in rivers, lakes, and rocks. Glaciology is the study of ice and ice sheets. This field looks at both large continental ice and smaller alpine glaciers. Climatology looks at weather patterns over a long period of time.

History shows how this science has grown over many years. In the Ancient Age, thinkers like Strabo and Eratosthenes studied locations. During the nineteenth century, Alexander von Humboldt viewed geography as a natural science. In the mid-1750s, Mikhail Lomonosov worked in Siberia. He studied how soil forms and how ice moves. His work helped start the new branch of glaciology. This was a very important time for the study of our world.

There are many specific ways to study the Earth. Biogeography looks at where different species live and why. This field grew from the work of Alfred Russel Wallace. Oceanography studies the oceans and the sea floor. It looks at everything from tiny marine life to huge ocean currents. Soil geography and pedology study how soil is spread across the land. Coastal geography looks at the meeting point between the ocean and the land. Even the last 2.6 million years are studied in Quaternary science.

These studies help us connect many different ideas. For example, environmental geography looks at how humans and nature interact. It brings together geology, weather, and water studies. Geomatics uses tools like maps and remote sensing to gather information. Scientists share what they learn in special journals. Some of these are called Nature or The Professional Geographer. By studying these parts, we learn how our whole planet works together.

Physical geography, also called physiography, is a major branch of natural science.

It focuses on the processes and patterns found in the natural environment. Scientists study several connected systems to understand our world. These include the atmosphere, which is the air around us. They also study the hydrosphere, the biosphere, and the geosphere. This branch is distinct from human geography, which studies the built environment. It is also different from technical geography, which focuses on tools for spatial information. However, these different branches often overlap in their research.

One major field is geomorphology. This is the study of the Earth's surface and how it is shaped. Geomorphologists look at how landforms changed in the past and how they change today. They use field observations, physical experiments, and numerical modeling. This modeling is often called geomorphometry. Geomorphology includes sub-fields like desert geomorphology or fluvial geomorphology. These focus on specific environments but share core tectonic or climatic processes. This work also provides a foundation for pedology, the study of soil.

Water is another vital part of physical geography. Hydrology focuses on the amount and quality of water on land. It examines water in rivers, lakes, aquifers, and even glaciers. This field often uses the hydrological cycle to explain how water moves. Hydrology has strong links to engineering and uses quantitative methods. It also includes sub-fields like limnology and ecohydrology.

Glaciology is another specialized area. It is the study of the cryosphere, which includes all ice phenomena. Glaciologists study both continental ice sheets and alpine glaciers.

Life and climate are also key areas of study. Biogeography examines the patterns of where species live and why. This field grew from the work of Alfred Russel Wallace. It is influenced by theories like evolution and plate tectonics. Biogeography includes sub-fields like zoogeography and phytogeography. Climatology is the study of climate, which is weather averaged over long periods. Climatologists look at both local microclimates and global macroclimates. They also study how humans and nature influence these patterns.

The study of the Earth's surface also involves soil and oceans. Soil geography looks at how soil is spread across different terrains. Pedology is the specific study of soils in their natural environments. It looks at soil morphology and how soil is classified. Oceanography is the branch that studies the Earth's oceans and seas. It is a diverse field that blends many different disciplines. Oceanographers study marine organisms, ocean currents, and the geology of the sea floor. They may specialize in biological, physical, geological, or chemical oceanography.

History shows how these sciences have evolved over time. In the Ancient Age, thinkers like Strabo and Eratosthenes studied locations. In the nineteenth century, Alexander von Humboldt viewed geography as a natural science. A major shift occurred during the European colonial expansion. This led to the creation of university departments and national geographical societies. In the mid-1750s, Mikhail Lomonosov conducted research in Arctic Siberia. He studied the organic origin of soil and the movement of ice. His work helped found the branch of glaciology.

Modern geography uses advanced tools and connections. Geomatics is the field of gathering and processing geographic information. It includes cartography and remote sensing, which uses devices to collect data from a distance. Environmental geography bridges the gap between human and physical geography. It analyzes how humans and the natural world interact. Finally, scientists share their findings through professional journals. These include publications like Nature and The Professional Geographer. By studying these many parts, we gain a complete view of our planet.
