1) how does our earth's surface look the way it does? 
 well, I think the earths surface looks like this because of time adn how people treat the envirornment and also bevause of erosions that happened over time, also the amount of water and sand we have aroung the world!  also natural disasters are a big part of how our earth looks the way it does because when some extreme diasaster like a volcano eruption happens it effects how the earth looks now. there are four types of erosions they are wind erosion, water erosion, chemicla erosion amf glacier eriosion. water erosion is when a big amount of water such as a flood or really heavy rain happens is creates canyons and etc. glacier erosion is when a big amount of glacier is moved across a land and over all the hills and mountains in that land. wind erosion is when wind picks up small pieces of sand from a dessert and creates wind erosion
