To talk about locations in the natural world, we often use the prepositions in<\/span> e on<\/span>.<\/strong> These small words help us say exactly where something is. For example, we say in the river<\/span> for something inside the water, and on the mountain<\/span> for something on its surface. Understanding the difference is important for clear communication in English. Think of in<\/span> for being *inside* or *surrounded by* something, like in the sky<\/span> ou in the forest<\/span>. Use on<\/span> for being *on the surface* of something, like on a tree<\/span> ou on the ground<\/span>. This lesson will help you use these prepositions correctly with common nature words at an A1 level, making your descriptions more precise and natural.<\/div>\n
