Answer:

They are named for the places where geologists first described rocks or fossils from that time.

Explanation:

The geological history of planet Earth is divided into multiple eras and periods. The divisions are based on some dramatic event that caused a significant change in a short period of time, thus creating an easy distinction between them. The purpose of the divisions is to be easier for the scientists to explore the past, to find it easier to describe fossils, rock strata, events, etc.

The names of the eras and periods of the geological time scale seem to be names that are familiar, at least to people in some regions, with slight changes at the end of the names. This is because the names of the eras and periods tend to be given by the places where geologists first described rocks or fossils from that time. As an example, we can take the Jurassic (named after the Jura Mountains), Devonian (named after the Devon), Cambrian (named after Cambria, which is the Latin name for Wales), etc.

Can anyone pls identify what type of sedimentary rocks these are. Thank you. This will react with acid
levacccp [35]

Answer:

Carbonate sedimentary rocks

Explanation:

Carbonate sedimentary rocks are the rocks that are primarily comprised of carbonate minerals such as calcite or aragonite. They are formed chemically. These rocks are formed when Carbon is initially trapped with the accumulation of sediments over it in association with fossil shells. They are also formed due to the dissolution or precipitation by groundwater, depending upon the temperature, pH and dissolved ions present in the solution.

They are often marked by the presence of karst topography and caves.

Some examples of these rocks are limestone and dolomite.

How does the movement of air affect the type of weather that forms from high-pressure and low-pressure systems?
Rom4ik [11]
Low pressure generally occurs in areas that are rainy and cloudy, whereas high pressure occurs in areas that are sunny and have mild temperatures. As air rises, it condenses into a low pressure, meaning clouds and rain. As air sinks, it creates a high pressure, meaning sunny.
