A striation of any length is a sure sign of glacial activity in the past. A striation is formed when a glacier scrapes moraine (load) against the rock face, forming a mark known as a striation. The mark shows that the area was once dominated by glacial activity.

Is striation erosional or depositional?

Striation is typically erosional. Striations are long, narrow lines or grooves on a rock surface caused by the movement of a glacier, which acts as a powerful scouring tool that can scrape and polish the bedrock beneath it as it flows.


Waves that travel at the surface such as Raleigh and long waves?

Raleigh waves are surface waves that occur in many types of media, such as water and the Earth's crust. They cause the ground to roll up and down in a wave-like motion during an earthquake. Long waves, or long-period ocean waves, are also surface waves that have longer wavelengths and occur in the ocean due to forces such as gravity and wind.


Which erosional feature most likely formed on the surface of the bedrock under the glacial ice?

Striations would most likely form on the surface of the bedrock under the glacial ice. Striations are caused by the movement of large rocks embedded in the base of a glacier scraping across the bedrock, resulting in long, parallel grooves being carved into the bedrock surface.


What effect would a long-term rise in the average surface temperature have on the ocean?

A long-term rise in the average surface temperature would lead to ocean warming, impacting marine ecosystems by disrupting habitats, altering species distributions, and potentially causing coral bleaching and other negative consequences. This warming could also contribute to sea level rise due to thermal expansion of water and the melting of polar ice caps and glaciers.


What is a long hole IN the ground to bring water to the surface?

A long hole in the ground used to bring water to the surface is called a well. Wells are typically constructed by digging or drilling deep into the earth's surface until reaching underground water sources, allowing access to water for various purposes such as drinking, irrigation, and industrial use.

If you saw long scratch marks on a flat rock surface you would suspect what?

I would suspect that the rock may have been scratched by a sharp object or dragged by something with enough force to leave a mark. The scratches could also be the result of natural weathering or geological processes over time.


What is a striation marking?

Striations are long, thin lines in the surface of something, usually multiple, and commonly all roughly or exactly parallel to each other. Picture dragging a stiff bristled floor broom across wet concrete - the marks it leaves behind are striations.

What happens if the officer coaches the suspect as to what to write on a voluntary statement?
