In geology, a graded bed is one characterized by a systematic change in grain or clast size from one side of the bed to the other. Most commonly this takes the form of normal grading, with coarser sediments at the base, which grade upward into progressively finer onesI just learned about this in our rocks and minerals unit for science,
Answer:
Lithospheric
Explanation:
Lithospheric plates are part of a planetary scale thermal convection system. The energy source for plate tectonics is Earth's internal heat while the forces moving the plates are the “ridge push” and “slab pull” gravity forces
Answer:
After an organism's soft tissues decay in sediment, the hard parts — particularly the bones — are left behind. Water seeps into the remains, and minerals dissolved in the water seep into the spaces within the remains, where they form crystals. ... If that mold gets filled with other minerals, it becomes a cast.
Explanation:
In Newton's Third Law of Motion, when one object exerts a force on a second object, the forces are equal in magnitude and opposite in direction. The correct answer is B.
<span>Answer: a) a series of anatomical traits that distinguish Cro-magnon features from Neandertals.</span>
<span>Neanderthals (Homo neanderthalensis) were first discovered in Germany in 1856 and are believed to emerged between 100,000 and 200,000 years ago. </span>
<span>Significant differences found in the human and </span>Neanderthal includes<span>: 1) their DNA, 2) the brain of a Neanderthal had a raised larynx and was also bigger, and 3) Compared to modern humans, Neanderthals had bigger and muscular body but with shorter legs.</span>
Cro-magnon is<span> the earliest known Western European example of our species who lived 35,000 and 10,000 years ago. They are believed to be actually modern in every anatomical respect. They are much like us.</span>
<span>Neanderthal and Cro-magnon were believed to overlap in Europe for a thousand years but long-term interbreeding was not seen. </span>
