widespread black shales were deposited on the north american craton in the late devonian and early mississippian periods. today they serve as source rocks for oil and gas.

Answers

Answer 1

Black shale is a type of sedimentary rock that forms under anoxic conditions (lack of oxygen) in the ocean.

These conditions can occur when there are high levels of organic matter in the water, such as during periods of rapid plant and animal growth. The organic matter decomposes and becomes buried in the sediment, eventually becoming black slate in the process of petrification.

Black shale is a common source rock for oil and gas because it contains high levels of organic matter that has been converted to hydrocarbons over time through the process of thermal aging. The organic matter in black shale is usually composed of algae and other microorganisms, as well as the remains of larger animals and plants.

The widespread deposition of black shale in North America during the late Devonian and early Mississippi may have been due to a combination of factors, including increased marine organic matter productivity and the presence of shallow seas where sediments could accumulate. highly sexual. Black shale deposits from this period have been found in many areas of North America, including the Appalachian and Williston Basins.

The Invention of Printing Press can increase the level of literacy rate in a country. This is true.

What is literacy?

The ability to read, write, speak, and listen in a way that enables us to effectively communicate and make sense of the outside world is known as literacy.

It is necessary to be literate in order to function in society, accomplish one's objectives, and expand one's knowledge and potential.

Applying a clear equity lens to understand gaps in developing educational policies and standards will be necessary for fundamentally improving literacy.

Only about 30% of European adults were literate when Johannes Gutenberg created the printing press in 1440. Since Gutenberg's invention, there has been an increase in literacy rates in Europe.

Letterpress printing has had a significant influence on education throughout history. The invention of letterpress printing in the middle of the fifteenth century made it possible to produce large quantities of books for distribution. Because more people could afford books to learn to read as a result, the literacy rate rose.

A scale drawing of Jerome's living room is shown below: A rectangle is shown. The length of the rectangle is labeled as length equal to 8 cm, and the width is labeled as width equal to 6 cm. If each 2 cm on the scale drawing equals 6 feet, what are the actual dimensions of the room? Length = 16 feet, width = 12 feet Length = 11 feet, width = 9 feet Length = 24 feet, width = 18 feet

Answers

The actual dimensions of Jerome's living room are length = 24 feet, width = 18 feet, hence option (C) is correct.

What are dimensions?

The power to which the fundamental quantities are increased in order to express a physical quantity is referred to as the dimension of that physical quantity. The symbols for mass, length and time are [M], [L], and [T], respectively. Height, length, and width are the three dimensions that define everything around us, including the homes in which we reside and the items we use on a daily basis.

Physical items are not the only things that can have dimensions. Two dimensions (2D) shapes only have two dimensions, like length and height. A 2D shape is something like a circle, square, or triangle. An object that is three-dimensional (3D) has three dimensions, including length, breadth, and height.

Given:

Since 2cm = 6 feet

So,

Length is = 4(6) = 24 feet

And, width is = 3(6) = 18 feet

True or False? Landslide-potential maps designate areas in which construction is illegal because of the high risk of mass movement there.

Answers

The statement, "Landslide-potential maps designate areas in which construction is illegal because of the high risk of mass movement there." is false.

The potential threat posed by landslides is depicted on many types of maps. These maps might be as straightforward as one that shows where past landslides have occurred to denote possible risk, or they could be as sophisticated as one that incorporates probabilities depending on elements like rainfall, slope angle, soil type, and earthquake shaking intensity.

Maps depicting the likelihood of landslides as well as the projected losses in lives and property, should one occur. Landslide hazard maps show the likelihood of landslides in a certain location. An ideal landslide potential risk map displays both the likelihood that a landslide will develop at a certain location and the likelihood that it will move downslope a specific distance.
