What type of rock is a ripple mark?
A ripple mark is not a kind of rock in and of itself, but a feature found in some sedimentary rocks, usually sandstones.
Why are sedimentary rocks so important for understanding the history of the Earth?
Through observation of sedimentary rocks, geologists are able to analyze rock layers and date the rocks by testing the carbon in each sample.
How many years do the majority of geologists believe it took for sedimentary rocks to form?
600 million years
Rocks formed from weathered debris from preexisisting rocks are called?
They are called clastic sedimentary rocks.
Rocks are to geologists as stars are to?
Rocks are to geologists as stars are to astronomers.
Which type of rock is likely to show ripple marks and fossils?
Sedimentary rocks show fossils, because of pre-existing life forms. They also show ripple marks due to weathering and erosion...
What are the markings on sedimentary rocks that record the wave motion of wind or water called?
Ripple marks
What are the markings on sedimentary rocks that record the wave motion of the wind or water called?
Ripple marks
What are the markings in sedimentary rocks that record the wave and motion of wind or water called?
"Ripple marks" (but you could also say cross bedding and dune bedding sort of do this too).
List four ways geologists classify rocks?
sedimentary,metormorphic , igneous .........
What are the three main categories into which geologists classify rocks?
Sedimentary, metamorphic and igneous.

Sedimentary rocks with ripple marks suggest that the rocks formed where?
Ripple marks in sedimentary rock were emplaced in sediments by near shore wave action, covered by additional sediments, and eventually lithified into a solid rock which becomes exposed by weathering and erosion of overlying material over large expanses of time.
What refers to the investigative process by which geologists identify and match sedimentary strata and other rocks of the same ages in different areas?
The investigative process by which geologists identify and match sedimentary strata and other rocks of the same ages in different areas is referred to as correlation.
How many years do the majority of geologists believe it took for sedimentary rocks to form?
600 million years
Rocks formed from weathered debris from preexisisting rocks are called?
They are called clastic sedimentary rocks.
