<p>Over the years and throughout history, our climate has changed. The greenhouse effect is a natural process that warms the Earth’s surface. When the Sun’s energy reaches the Earth’s atmosphere, some of it is reflected back to space and the rest is absorbed and re-radiated by greenhouse gases. This is demonstrated in the illustration within this puzzle. You will learn all about the atmosphere, carbon dioxide from cars and other forms of transport, and the needs of the plants. The puzzle displays how solar heat is being trapped and returned to the earth by the greenhouse gasses in the atmosphere. It shows how animals need plants to eat and breathe. Without sunlight, the plants will not grow and therefore will result in no reproduction of humans or animals, as the plants release oxygen for us all to breathe. The puzzle comes complete with 69 custom-cut pieces and is best suited for slightly older children learning about our climate.</p> <p>with 69 pieces</p>
