1 00:00:00,000 --> 00:00:09,000 Hello everyone! I'm going to show you the course of a river and the parts of the river. 2 00:00:09,000 --> 00:00:20,000 I have made a market of a river basin, that is an area of land that drains into a river. 3 00:00:20,000 --> 00:00:35,520 There are three parts in a river, the upper course, the middle course, and the lower course. 4 00:00:35,520 --> 00:00:40,280 And the river begins in the source. 5 00:00:40,280 --> 00:00:48,240 In the upper course, the river goes very fast, this forms waterfalls. 6 00:00:48,240 --> 00:00:59,679 Then the river reaches the middle course and it goes in a speed of medium. 7 00:00:59,679 --> 00:01:06,760 The middle course form meanders that are bends of a river. 8 00:01:06,760 --> 00:01:15,319 Tributaries are tiny rivers that flow into a large river like this one. 9 00:01:15,319 --> 00:01:19,799 This is the tributary and this is the large river. 10 00:01:21,180 --> 00:01:28,760 The lower coast is where the river finishes because here is the mouth. 11 00:01:29,359 --> 00:01:40,980 And in the mouth, the river reaches the sea or ocean and it goes to the sea or ocean. 12 00:01:40,980 --> 00:01:49,980 Deltas form when the water reaches the sea or the ocean. 13 00:01:49,980 --> 00:01:53,980 Thank you for watching!
