Then what is it then

Geographers study the Earth and its various components to understand how they interact and influence each other. In the process, geographers explore how Earth and its people affect different aspects.

One area of study is how Earth and its environment impact human health. Geographers examine factors such as air quality, access to clean water, and the presence of natural hazards like earthquakes or floods to understand their implications for human well-being. They also analyze how human activities such as urbanization or industrialization can influence public health.

While geographers primarily focus on studying Earth, it's important to clarify that their scope doesn't extend to examining the solar system. Geographers typically concentrate on Earth's physical features, its atmosphere, climate, and the interaction between human societies and the environment.

Moreover, geographers also investigate how humans and Earth affect each other. This involves studying the ways in which human activities, such as agriculture, mining, or urban development, shape the physical landscape and natural resources of the planet. Additionally, geographers explore the impacts of human-induced changes, like climate change or deforestation, on Earth's ecosystems and biodiversity.

Lastly, geographers examine the relationship between Earth, its people, and political systems. They analyze how political decisions and policies influence the environment, resource management, and urban planning. Geographers may investigate topics such as political boundaries, territorial disputes, or the impact of globalization on different societies.

To learn about how Earth and its people affect other aspects like the solar system, one would need to consult experts from fields such as astronomy or astrophysics. These disciplines specifically focus on studying celestial objects, the universe, and interactions between Earth and the rest of the cosmos.
