Ripple mark formation. Ripple marks are one of the most common bedforms found in the intertidal zone of the beach. They are also a very common feature in ancient rocks. Ripple marks form any place where there are the right kind of winds, waves and currents. They form on the dunes, the beach, on the shoreface, or way offshore on the continental ...Question: Q.4/ Give brief answer the following questions; - 1) is associated with mountains building. 2) The only fold that has two axial planes is 3) Nominate five processes of weathering. 4) What do mean by axial plane? 5) There are four types of stylolite's, stylolite, and 6) Symmetric ripple marks indicate 7) Which is more extending, physical weathering orripple marks are symmetrical. A rough mechanical analysis of the sand in this rock is as follows: Diameter of Grains Percentages in Millimeters by Weight I/8 -I/6 80 I/16-I/32 20 Two years ago I found ripple marks of the same size, or possibly slightly smaller, forming in some fine sandy silt in the Rio Grande, in Webb County.

Sedimentary structures, like those in Figure 7-2, are commonly preserved in sediment (e.g., ripple marks, mud cracks, etc.). Sedimentary rocks can form from loose sediment of various sizes (i.e., mud, sand, gravel), from mineral crystals (like silica or calcite) that evaporate or precipitate from water, or from the accumulation of organic material. are a sure sign that the area had periodic droughts. FEEDBACK: Symmetric ripple marks require an oscillating current, such as those created by waves at the coast, in permanent shallow water (not deep lake bottoms), and they form at right angles (not parallel) to the direction of the current. 1 / 1 pts Question 18 (Q018) This diagram is a cross section of …Current ripples are asymmetric, with gentle upstream face ( stoss side) and steep downstream face ( lee side) approaching or at angle-of-repose. Individual current …Ripple marks develop in soft beds of sand in shallow water. The two directional movements (back and forth) of waves create symmetric ripple marks. Asymmetric ripple marks occur when waves move in one direction. Graded beds form when there is rapid deposition with water that has varying sizes of sediment, making the sediment coarse at the bottom ...Question: (25 Mark) Q.4/ Give brief answer the following questions: is associated with mountains building, 2) The only fold that has two axial planes is. 3) Nominate five processes of weathering. 4) What do mean by axial plane? 5) There are four types of stylolite's stylolite, 6) Symmetric ripple marks indicate 7) Which is more extending physical weathering or
