Why can you see layers in foliated rocks but not in nonfoliated rocks?

Because layers from foliated rocks came from the same direction and nonfoliated rocks came from several directions

What are the layers of rock made of?
Layers or strata in sedimentary rock are composed of deposited smaller rock particles and possibly organic matter.
How would you know the difference between igneous and sedimentary and metamorphic rock?
Sedimentary rocks tend to have layers. Igneous rocks tend to have crystals. If you don't see layers or crystals, the rock might be metamorphic.
What does rock composition mean?
Igneous rock composition basically means how the rock would look if you were to cut it in half. In the case of igneous rock, you would see the different layers of rocks that have melted with it.
What Causes rock to flake off in layers?
Different erosional features can lead to layers of rock flaking off. In layered sedimentary rocks this is usually the case when some of the layers are less resistant against weathering (e.g. when the grains are cemented by carbonate which is dissolved by acid rain). One can often see that phenomenon on old sandstone buildings. Also igneous rocks show the effect of layers flaking off the surface. This may be related to thermal expansion and contraction working mostly on the outer part of large boulders. It might as well have something to do with the structure of the rock inherited from its crystallization and residual stresses and the depth that water can penetrate and weather the rock. Another answer: The flaking off in layers of rocks is called exfoliation. This usually occurs in deserts and is caused by changes in temperature.
What clues or characteristics do you look for i n order to identify sedimentary rocks?
== == Sedimentary rocks may exhibit strata, or layering. Sandstones will have visible sand grains. Limestones will fizz when placed in vinegar. Fossils usually only appear in sedimentary rocks. A rock made of an assortment of other rocks is usually sedimentary.

Where can I get information about non foliated and foliated metamorphic rocks for my science report?
See link for the Wikipedia article.
Is limestone a foliated rock?
No. Foliation is a word used to describe metamorphic rocks that have undergone deformation which has caused an alignment of their crystals. Foliated rocks often appear to have "bands" of minerals. To find out more and to see a picture of a foliated rock - in this case a Gneiss, please see the related link.
Which rocks are commonly non foliated?
Some common non foliated rocks include sandstone and limestone. The majority of rocks are non-foliated as foliation is a rock texture caused most commonly by the recrystallisation of rocks that have undergone metamorphism. However it can also occur in igneous rocks due to the alignment of crystals during crystallisation and the formation of cumulates in a magma chamber or due to frictional drag forces between a magma and the magma chamber walls and also form in lava flows. Please see the related links.

What are some ways to use 'non-foliated' in a sentence?
The geologist could see that the metamorphic rock was non foliated as it did not contain aligned minerals in bands.
Talk about the patterns you can find in sedimentary rocks. Where do you see these patterns?
Sedimentary rock is formed when many rocks are broken into small pieces by erosion, after a long time the small rocks fuse together and become a rock with many different layers.
Why are geologists interested in outcrops and cliffs?
In outcrops and cliffs it is possible to see multiple layers of rock exposed in one place, which makes it easier to study a set of rocks.
What does rock composition mean?
Igneous rock composition basically means how the rock would look if you were to cut it in half. In the case of igneous rock, you would see the different layers of rocks that have melted with it.
In photoshop where do you look to see how many layers are in an image?
Open the Layers window.
Are rock layers always younger than the faults that cut across them?
If the situation is as simple as the one you have stated, it isn't difficult. Meanwhile, many faults displace laterally, either in compression or tension so that it can appear that younger rocks overlie older ones. See the law of super-position. Compressive faults generally force younger rocks below older, but not always. See subduction zones. Then see ophiolite suites.
