How did ancient American Indian cultures use Clovis and Folsom points quizlet?

The Clovis culture used Clovis points, or arrowheads. These points were between 4 and 6 inches long and had fluted points. The Clovis used these points along with atlatls to hunt large game like mammoths. The Folsom culture also used points to hunt; however, their points were slightly different.

Which are factors that influence the type and rate of weathering a rock undergoes choose all that apply?

Rainfall and temperature can affect the rate in which rocks weather. High temperatures and greater rainfall increase the rate of chemical weathering. 2. Rocks in tropical regions exposed to abundant rainfall and hot temperatures weather much faster than similar rocks residing in cold, dry regions.

What may include sand rocks pebbles soil dust and other particles?

D Geologist 5 Movement or rocks and sediment that have broken apart. 6 May include sand, rocks, pebbles, soil, dust and other particles. 7 The person who studies rocks and minerals.

Which geologic feature is caused primarily by chemical weathering?

The most common feature that can be caused purely by chemical weathering is Karst Landscape, which can lead to caverns and sinkholes.

What did Archaeologists find in the cave at Diuktai?

Most of the stone artifacts at Dyuktai Cave are waste from tool production, consisting of wedge-shaped cores and a few single-platform and radially flaked cores. Other stone tools included bifaces, a wide variety of shaped burins, a few formal scrapers, knives and scrapers made on blades and flakes.

How did the first people get to America?

The settlement of the Americas is widely accepted to have begun when Paleolithic hunter-gatherers entered North America from the North Asian Mammoth steppe via the Beringia land bridge, which had formed between northeastern Siberia and western Alaska due to the lowering of sea level during the Last Glacial Maximum ( …

What are weathering agents?

Weathering describes the breaking down or dissolving of rocks and minerals on the surface of the Earth. Water, ice, acids, salts, plants, animals, and changes in temperature are all agents of weathering.

What is the agent of weathering?

Water, ice, acids, salts, plants, animals, and changes in temperature are all agents of weathering. Once a rock has been broken down, a process called erosion transports the bits of rock and mineral away. No rock on Earth is hard enough to resist the forces of weathering and erosion.

What is a major agent of chemical weathering because water?

water expands when it freezes. water is a major agent of chemical weathering because water. dissolves many of the minerals that make up rocks. You just studied 105 terms!

Which rock layers in the formation appear to be the most resistant to weathering?

Igneous rocks are usually solid and are more resistant to weathering. Intrusive igneous rocks weather slowly because it is hard for water to penetrate them. Sedimentary rocks usually weather more easily. For example, limestone dissolves in weak acids like rainwater.

How are rocks formed step by step?

Formation of rocks. Sedimentary rocks are formed through the gradual accumulation of sediments: for example, sand on a beach or mud on a river bed. As the sediments are buried they get compacted as more and more material is deposited on top. Eventually the sediments will become so dense that they would essentially form a rock.

What is the process of breaking up rocks called?

Updated April 08, 2018. The process known as weathering breaks up rocks so that they can be carried away by the process known as erosion. Water, wind, ice, and waves are the agents of erosion that wear away at the surface of the Earth.

What is the synthetic investigation of rocks?

The synthetic investigation of rocks proceeds by experimental work that attempts to reproduce different rock types and to elucidate their origins and structures. In many cases no experiment is necessary.

How do weathering and weathering break up rocks?

The process known as weathering breaks up rocks so that they can be carried away by the process known as erosion. Water, wind, ice, and waves are the agents of erosion that wear away at the surface of the Earth. Water is the most important erosional agent and erodes most commonly as running water in streams.
