topic: Rocks activity: Sedimentary rocks Question 1 Assign a number to each of the five steps of clastic sedimentary rock formation shown here to indicate the correct order in which they occur. ____ Lower layers compact under the weight above. ____ Erosion transports the weathered material. ____ Rock is broken down into pieces by weathering. ____ Minerals dissolve, cementing sediment into rock. ____ Sediment settles and is deposited into layers. Question 2 Observe the following sedimentary rocks and comment on how their features help explain how they were formed. ADD SANDSTONE/LIMESTONE & CONGLOMERATE Show rocks, provide text input space Question 3 © IntoScience 2013.

The rover drilled rock samples at the Sheepbed mudstone (shown lower left) and scientists estimated they have only been exposed at the surface for approximately 80 million years. This is unexpectedly quite young. Which process would likely explain the exposure of these younger layers of rock? (circle one) Tectonic plate uplift from the ocean floor Weathering and erosion Folding due to high temperature and pressure Current volcanic activity (b) Describe the features of the Gillespie Lake sandstone that might indicate that this is a sedimentary rock? © IntoScience 2013.

(d) Research what layers of Martian sedimentary rocks tell us about the history of Mars. (e) Do you believe the presence of sedimentary rocks on Mars provides evidence that life on Mars once existed? © IntoScience 2013.
