Question

Dinosaurs once stomped across the Yukon, leaving tracks in mud that were buried in more mud and hardened to stone. Some may have been turned on end or turned over by mountain building; others were split apart and turned over by humans looking for dinosaur tracks and putting them in museums. The light was shining in from the upper right, as indicated, making lighter-looking and darker-looking places depending on whether they were facing the light or in shadow; we have indicated a shadow of the human glove and of the dinosaur track to help guide your eye. Is the rock now upside-down (you are looking at the side that was down when the sediment was soft) or right-side up (you are looking at the side that was up when the sediment was soft)?

Answer 1

You forgot to provide the image needed for the question to be answered. The image is attached below

Answer:

Upside down

Explanation:

According to the indication of shadows in the figure, we can see the shape of the foot of the dinosaur that stepped on that rock. This is because we can see a slight formation of fingers and nails in the right corner of the image. In this way, if you analyze the position of the foot presented on the rock, we will notice that the rock is positioned upside down, which indicates that you are looking at the side that was down when the sediment was soft.

Answer 2

In this question, we are not provided with the image of the dinosaur track. Because of this, we are unable to tell whether this specific track is right-side up or upside-down. However, we can give you some guidance so that you can identify this on your own.

In general, in this type of prints, mud cracks extend downward into soft sediment. These cracks mean that when more sediment is washed in, the second layer fills the cracks beneath. Afterwards, once the layers have hardened, the rock may be cracked apart. Based on this, we can conclude that if you see troughs in a mud-crack pattern, you re looking at the second layer, which was originally right-side up.
