First step - draw a strike line where line A intersects the 400 m line.
Second step - you know that the sandstone layer is of equal thickness and dip, so you can draw a parallel line at the place with line B intersects the 400 m line. This will give you the thickness, as expressed on a horizontal surface. You know what the dip angle is, so getting the real ...

The workflow of fusing RGB true color image and panchromatic grayscale image can help understand this question. After converting RGB color space to the IHS space, the intensity component is replaced with the (high-resolutional) panchromatic image, and then the new intensity, hue, saturation combination as IHS are converted back to the original RGB space.

This is a tale of two three dimensional coordinate systems. You may need to take a bit of a side track if your students are not already familiar with the concepts of three dimensional coordinate systems, three dimensional vectors, the three dimensional dot and cross products, and transformations between coordinate systems. The image below portrays two such ...

Not knowing the setting and judging from the image alone in this trampled environment, I think we're looking at a form of chemical weathering called "spheroidal weathering".
The gist is this (from the linked wiki page):
Penetrating water alters the bed-rock along cracks or joints, causing volume changes between altered and unaltered parts. These ...
