Back Start Next Adapting to the Climate The map shows where in the world you came from. You are buried at 46 degrees north latitude. Draw an imaginary line across the map. Which states or provinces share the same latitude? Look at the photo taken from outer space. What do you notice? Imagine it is winter now. You are in the mountains. It can get to 40 degrees below zero there. Most of the water is frozen. What would happen if you came out of the ground during the winter? Plants that did that didn't live. Your ancestors survived because they poked out when conditions were right. Now you naturally do the same. In fact, you need at least two months of cold underground temperatures before you'll pop out of the ground.
