Answer:
Ripple marks are caused by water flowing over loose sediment which creates bed forms by moving sediment with the flow. Bed forms are linked to flow velocity and sediment size, whereas ripples are characteristic of shallow water deposition and can also be caused by wind blowing over the surface.
Explanation:
Students are investigating the rocks with fossil markings that are found in an area that was once covered by a lake. The rocks they are observing are MOST likely —
igneous
metamorphic
sedimentary
thermic
Answer:
sedimentary rock
Explanation:
The rocks they are observing are MOST likely sedimentary. The correct option is C.
What is sedimentary rock?Sedimentary rock is one of the three main types of rock formed on Earth (the others being igneous and metamorphic rocks). It is formed by the accumulation and solidification of sediment, which is any material that is transported by wind, water, or ice, and eventually deposited on the Earth's surface. This can include particles of minerals, rocks, and organic matter.
Over time, these sediments are buried and subjected to pressure and compaction, which causes them to become more tightly packed and solidified. The weight of the overlying layers can also cause the sediment to undergo cementation, where minerals dissolved in water between the particles precipitate and bind them together. As the sediment becomes more compacted and cemented, it eventually becomes a solid rock.
Sedimentary rocks are often characterized by their visible layers or strata, which can contain fossils and provide a record of past environmental conditions. They are also important sources of natural resources, such as coal, oil, and natural gas, as well as many of the minerals and building materials used in construction. Some common examples of sedimentary rocks include sandstone, shale, and limestone.
Here in the question,
Sedimentary rocks are formed from the accumulation and consolidation of sediment, often containing fossils. The fact that the area was once covered by a lake supports the idea that the rocks would have been formed from sediment deposited in the lake. Therefore, option C is the most likely and correct choice.
Igneous rocks are formed from molten magma and do not typically contain fossils. Therefore, option A is not correct.
Metamorphic rocks are formed from preexisting rocks that are altered by heat and pressure. They also typically do not contain fossils. Therefore, option B is not correct.
Thermic is not a commonly used term in geology, so option D is not a valid choice.
Therefore, The correct option is C. sedimentary.

Why do you see objects when you shine a flashlight in a dark room?
Answer:
We see objects in a dark room due to the emission of light photons which are sensitive to our eyes. Darkness is simply a terminology used to describe the absence of light. Visible light to human is a component of the electromagnetic spectrum. Our eyes have receptors that picks the photons which light releases

Explain why an X-linked recessive trait is expressed more commonly in males than in females.
Answer:
X-linked recessive inheritance
A male with a mutation in a gene on the X chromosome is typically affected with the condition. Because females have two copies of the X chromosome and males have only one X chromosome, X-linked recessive diseases are more common among males than females.
