now you were doing the Gangnam Style dance very nice you also look very happy what's the reason that's great you watch the nervous system video two times and you got 10 out of 10  what is there in that second paper you got a test tomorrow when weathering and erosion that's why you seem worried don't worry let's learn about it now but first go to the bathroom and wash your hair why what do you mean why because you were touching your pee pee part with your hands come clean your hands  thought you forgot to turn off the tap the sea what's been weathered and eroded by the water I don't look surprised yes the soap has been weathered and eroded by water so your lesson Starts Now take this up with you so let's learn about weathering and erosion remember to secret codes the weathering code is breaking and the erosion code is to take away  remember weathering and erosion keep happening from moment to Moment Like Big Rocks which keep getting broken and small parts of rocks which are play Carried Away by water or wind forces yeah you're right weathering and erosion happen to this soap and it was caused by water water first wrote the self and then carried away the broken part  can you give some more examples  oh yes you are causing weathering when you break the Rock  yes wind has taken away the broken parts which is erosion weathering and erosion caused many changes all around us look at these pictures mountains rivers many more things keep changing their size and shape due to weathering and erosion I hope this far we have understood the difference between weathering and erosion now let's learn more about how it happens in nature first let's look in weathering weathering can be caused by many factors for example water breaks down rocks and soil into different ways one way is when it rains water seeps through rocks from small cavities in the night when the temperature becomes lower the water freezes this frozen water more space so it puts pressure on the surrounding Rock which then breaks down yep you're right it's like putting a nail in the Rock and then the rock breaks down when it tries to space for the nail there is another way in which water causes weathering water in the river breaks the soil on the sides by first making it soft and wet lights are also responsible for weathering see a plant is growing on a rock its roots are going deep in search of water the roots are trying to make space to grow further which was can cracks in breakdown in the Rocks another cause of weathering is wind wind carries a lot of dust and sand particles when these particles keep hitting the Rocks year after year gradually the Rocks were down yes it's the same as sharpening the lead of a pencil with a piece of sandpaper as the grains of sand in the Sandpaper rub against the lead over an the lad begins to break down  so weather in can be caused by water wind or even plants and you saw the temperature can also play a role since water freezes at low temperatures this kind of weathering is called physical weathering there is another kind of weathering called chemical weathering there are many gases and many men those in our environment they keep reacting to each other and many times it causes weathering for example when oxygen reacts with iron minerals within rocks it forms rust this can also result in the breaking of rocks sometimes chemicals in our atmosphere combined with water which causes acid rain these acid rains are also respond for weathering  so now you understand two different kinds of weathering but remember in nature this breaking down does not happen in days or months it takes hundred thousands or sometimes millions of years  erosion happens in many ways it keeps happening along with weathering like the soil on the Riverside which is first broken by the pressure of the water and then falls down into the river where water carries it to different places and also plays a major role in carrying away broken particles see here a farmer is plowing his field this plowing causes many broken soil particles which are then Away by the strong wind so we learned today then weathering and erosion are two major factors which keep changing the world around us and they keep working together at the same time so we learned about different kinds of weathering and erosion are you ready for your test now I have a question for you tell me the two secret codes of weathering and erosion very good I hope that you get another 10 out of 10 on your test I guess you can keep dancing
