Movements Inside the Earth

One fascinating thing students learn in class 7 geography chapter 3 is how our Earth is always changing due to movements inside it. These movements happen in the lithosphere, which is made up of lithospheric plates. These plates are in constant motion due to molten magma beneath Earth's surface. The forces behind these movements are of two types: Endogenic forces, which work from within the Earth, and Exogenic forces, which act on the Earth's surface. The Endogenic forces can cause earthquakes, volcanoes, and landslides. On the other hand, Exogenic forces shape the various landforms we see on the surface.

What is a Volcano?

In simple terms, a volcano is an opening in the Earth's crust. Molten rock known as magma comes out through this opening as lava, forming a volcano. This topic is essential to understand the "our changing earth class 7 questions and answers."

What is an Earthquake?

Earthquakes are a result of the shifting of lithospheric plates inside the Earth. The point where this movement begins is called the focus, and the point directly above it on Earth's surface is known as the epicentre. The closer you are to the epicentre, the more the impact. Earthquakes are measured on the Richter scale, making it a key point in class 7 geography chapter 3 question answer studies.

Movements on the Surface of the Earth

While earthquakes and volcanoes happen due to internal forces, other changes like valleys, hills, and rivers are formed by external forces like weathering and erosion. Here, elements like water, wind, and ice play a significant role.

Work of a River

Running water, like rivers, carves out valleys, waterfalls, and even helps in creating fertile lands due to sediment deposits. Students learn these in detail through the "class 7 geography chapter 3 short questions and answers."

How are Beaches Formed Class 7th?

Beaches are formed by the constant deposit of sediments along the shore by sea waves.

Work of Ice and Wind

Glaciers and wind also significantly change the Earth’s surface. Glaciers carve out valleys and create lakes, while wind can erode and deposit sediment, forming structures like sand dunes.

What is Erosion Class 7?

Erosion is the wearing away of Earth's surface by natural agents like water, wind, and ice. This is a crucial concept in "ncert class 7 geography chapter 3."

Why is our environment changing

The environment is changing for a variety of reasons, both natural and human-made.

Natural Changes

Earth has always been subject to natural changes. Factors like volcanic eruptions, earthquakes, and natural climate fluctuations have historically brought about significant changes. Seasonal cycles, animal migrations, and plant growth also contribute to smaller-scale, cyclical changes in the environment.

Human Activities

However, in recent times, human activities have significantly accelerated the pace of environmental change. Here are some reasons:


The rise of industries has led to increased pollution, including air and water pollution. Factories emit harmful gases and chemicals, contributing to issues like global warming and water contamination.


Trees absorb carbon dioxide and provide oxygen, among other benefits. Cutting them down for land and lumber means less CO2 is absorbed, affecting the atmosphere and leading to climate change.

Overfishing and Hunting

Overfishing in the oceans and excessive hunting on land have led to the depletion of many species, affecting biodiversity.


Modern agricultural practices often involve the use of pesticides and fertilizers that can harm local ecosystems. Also, the need for more agricultural land leads to deforestation.


Increasing consumerism has led to more waste, including non-biodegradable materials like plastics, which harm animal life and ecosystems.


As cities expand, they take over more land, affecting local ecosystems and often leading to increased pollution.

Climate Change

Human activities have contributed to climate change, which in turn affects weather patterns, sea levels, and habitats.


Whether you're studying "class 7th geography chapter 3 question answer" or exploring the "class 7 geography chapter 3 questions and answers pdf," knowing how our Earth changes due to various natural forces is fascinating. From understanding why earthquakes happen to learning about how rivers and glaciers shape our world, class 7 geography chapter 3 covers it all. So next time you see a mountain, valley, or river, you'll have a deeper understanding of the forces that helped create them.
