Have you ever wondered what the world would be like if all the continents were still joined together as one giant landmass called Pangea? Let’s explore some interesting ideas about how life on Earth might be different!
One of the most important things about Earth’s history is how different species have evolved. When continents are separated, like Australia and Madagascar, they become unique homes for many plants and animals that can’t be found anywhere else. If Pangea had never broken apart, we might not have such a wide variety of life forms. This is because isolated places help new species to develop and thrive.
If Pangea were still around, the climate would be quite different. Coastal areas would be great places for life to flourish because they would have access to water and moderate temperatures. However, the middle parts of this supercontinent would be very hot and dry, almost like deserts. This is because clouds would lose their moisture before reaching these areas, making it hard for plants and animals to survive there.
With all the land connected, ocean transportation might not be as important as it is today. People could travel across the land to reach different places. But there’s a fun side to this too! Imagine beaches stretching for thousands of miles. Beach-goers and surfers would have endless coastlines to enjoy, making it a paradise for those who love the sea.
While it’s fascinating to think about what life would be like if Pangea never broke apart, it’s also important to appreciate the world we live in now. The separation of continents has helped create the amazing diversity of life we see today, and it has shaped the environments and cultures we know and love.
Imagine what the world would look like if Pangea still existed. Use a large sheet of paper to draw a map of Pangea, labeling current countries and continents. Think about where different climates might be and how animals and plants would adapt to these environments.
In groups, choose a unique species from a continent like Australia or Madagascar. Role-play how this species might have evolved differently if Pangea had never broken apart. Present your ideas to the class, explaining how isolation affects evolution.
Conduct a simple experiment to understand how moisture affects climate. Use sponges to represent clouds and a large tray of sand for land. Observe how water travels and discuss how this relates to the dry central areas of Pangea.
Hold a debate on the pros and cons of land versus ocean transportation if Pangea still existed. Consider how travel and trade would change and what new challenges and opportunities might arise.
Design your own endless beach resort on Pangea. Think about what activities and features would attract visitors. Present your design to the class, highlighting how the geography of Pangea influences your choices.

It’s AumSum Time. What if Pangea never broke apart?
Firstly, it would have been very detrimental to the diversity of life forms on Earth. Earth’s history shows that isolated geographic landmasses are crucial for the evolution of new species. For example, isolated landmasses like Australia and Madagascar have many species that are not found anywhere else.
Secondly, life would have thrived in coastal areas, but the deep interiors would have become extremely hot and arid, experiencing almost desert-like conditions as clouds would have lost their moisture before reaching them.
Thirdly, ocean transportation would have diminished in significance, as everyone would be connected by land. However, on the positive side, beach-goers and surfers would have been quite happy, as beaches would have stretched for thousands of miles.

Pangea – A supercontinent that existed millions of years ago, where all the Earth’s landmasses were joined together. – Scientists believe that Pangea began to break apart about 175 million years ago, leading to the formation of the continents we know today.
Continents – Large landmasses on Earth’s surface, such as Africa, Asia, and Europe. – There are seven continents on Earth, each with its own unique geography and ecosystems.
Species – A group of living organisms that can interbreed and produce fertile offspring. – The giant panda is an endangered species that lives in the bamboo forests of China.
Climate – The typical weather conditions in a particular region over a long period. – The climate in the Sahara Desert is extremely dry and hot, with very little rainfall.
Environment – The surroundings or conditions in which a person, animal, or plant lives or operates. – Protecting the environment is crucial for maintaining biodiversity and ensuring clean air and water.
Transportation – The movement of people or goods from one place to another. – Rivers have been used for transportation for centuries, allowing people to travel and trade goods.
Beaches – Sandy or pebbly shores along a body of water, often popular for recreation. – Many tourists visit the beaches of Hawaii to enjoy the sun, sand, and surf.
Life – The existence of living organisms, including plants, animals, and humans. – The rainforest is teeming with life, from colorful birds to diverse plant species.
Diversity – The variety of different species, ecosystems, or genetic variations within a certain area. – The Amazon Rainforest is known for its incredible biodiversity, hosting thousands of different species.
Plants – Living organisms that typically grow in soil and use sunlight to make their own food through photosynthesis. – Plants like trees and flowers are essential for providing oxygen and food for many other living creatures.
