Answer:

<u>Foliation </u>

Explanation:

  • It is a type of flat or planar feature looking like the layer of the rock that is created by the alignment of the platy minerals such as mica.  Thus they exist in bands of light and dark color rocks with the interlocking grains having no specific patterns.
  • Slate has a low metamorphic grade where the minerals are not visible with the naked eye thus usually dark-colored rock. Schist is a medium coarse-grained rock with the visible regions of mica and are often shiny due to reflections is a product of the intermediate grade.
  • And gneiss a course-grained rock usually of lighter and darker bands of rocks with the highest grade of foliation.

Does anyone know how to do transformation
Ipatiy [6.2K]
I can't see the picture, but to do the dilation you must first figure out the coordinates of the first image and then figure out what half of it is and add that on to the new image or take that much off of the new image.

*To dilate means to make bigger or smaller

this fossil was found in a dry, mountainous area. What can you infer about how the area has changed over time?
WINSTONCH [101]

Fossils are the remains of plants and animals that have been preserved for millennia in stones under the Earth's surface. They contain the long chapters of the history of our Earth. Fossils tell us what the earth looked like many millions of years ago, what kind of animals and plants lived on its surface and how it was changing. Fossils show us a history of over a billion years old.


From the fossil from a dry, mountainous area we can conclude that the area was once underwater and over time the soil has risen as result of continental drift and uplift. So, a mountain was once the bottom of a prehistoric ocean or sea.
