The Earth is about 12,000 km in diameter. It is therefore how many orders of magnitude wider than you are tall? (i.e., the Earth’s diameter is how many times larger than your height (give an order-of-magnitude estimate)?) (I am 5'2")
If you start at the equator and travel to 10 degrees north approx. how many kilometers (or miles) north of the equator will you be? Take the circumference of earth to be 40,000 kilometers (24,900) miles).
