Which is NOT an example of unconformity that occurs in rock layers? * 1.)Rock layers are curved. 2.) Rock layers are flat and horizontal. 3.)Rock layers have wavy lines between them indicating erosion. 4.)Rock layers change from igneous to sandstone.
Answers
Answer:
Sedimentary rocks are laid down in layers called beds or strata. A bed is defined as a layer of rock that has a uniform lithology and texture. Beds form by the deposition of layers of sediment on top of each other. The sequence of beds that characterizes sedimentary rocks is called bedding
Unconformities are gaps in the geologic rock record. They are surfaces of contact between older rocks and younger sedimentary rocks, formed due to erosion or lack of sediment deposition over extended periods of time.
Igneous rocks are made from the rapid or slow cooling of magma/lava.
Metamorphic rocks change form based on the influence of heat, pressure, or chemical activity.
Sedimentary rocks are essentially formed by pieces of smaller rocks, fossils, and sediments.
