1 99:59:59,999 --> 99:59:59,999 Hi guys, 2 99:59:59,999 --> 99:59:59,999 the objective of this video is to look at 3 99:59:59,999 --> 99:59:59,999 the bedding structures that form when sediment is deposited. 4 99:59:59,999 --> 99:59:59,999 These bedding structures all form in different environments. 5 99:59:59,999 --> 99:59:59,999 These environments which create the bedding structures will be discussed. 6 99:59:59,999 --> 99:59:59,999 Firstly, we will talk about the horizontal beds, 7 99:59:59,999 --> 99:59:59,999 or strata, that the sediment is laid down in. 8 99:59:59,999 --> 99:59:59,999 Sedimentary rock is stratafied, which means that it has layers. 9 99:59:59,999 --> 99:59:59,999 These layers have formed because sediment is laid down in horizontal layers called strata. 10 99:59:59,999 --> 99:59:59,999 Between each layer of strata, we have bedding planes. 11 99:59:59,999 --> 99:59:59,999 And these bedding planes form because the region has experienced 12 99:59:59,999 --> 99:59:59,999 a change in depositional environment or material. 13 99:59:59,999 --> 99:59:59,999 We can see here in this photo that we have had one type of sediment laid down 14 99:59:59,999 --> 99:59:59,999 And then, a change in depositional environment 15 99:59:59,999 --> 99:59:59,999 has caused a different type of sediment to be laid down on top, 16 99:59:59,999 --> 99:59:59,999 in between which is a bedding plane. 17 99:59:59,999 --> 99:59:59,999 We know that the strata towards the bottom of a series is older 18 99:59:59,999 --> 99:59:59,999 than the strata at the top. 19 99:59:59,999 --> 99:59:59,999 And this happens because the sediment is laid in this way. 20 99:59:59,999 --> 99:59:59,999 Bedforms are formations that occur due to the movement of wind and water. 21 99:59:59,999 --> 99:59:59,999 Bedforms are created when water or wind, flows over loose sediment. 22 99:59:59,999 --> 99:59:59,999 And the shape and
