How are eras and periods of the geologic time scale named?

•They are named for the places where geologists first described rocks or fossils from that time.
•Their names are based on the names of scientists who discovered the rocks and fossils.
•They are named after plants and animals that lived during that time.
•Their names are based on the number of centuries within that length of time.

Answers

Answer 1

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.

true/false. regional metamorphism is a common, widespread type of metamorphism typically associated with mountain building where large segments of the crust are deformed by the collision of two colliding blocks.

Answers

Answer:

true

Explanation:

Regional Metamorphism occurs on a large scale, typically involving hundreds of square kilometers of surface area. It is the most widespread of the metamorphic types and is typical of the major fold-mountain belts such as the Appalachians, Himalayas, Alps or Rocky Mountains.

The given statement "regional metamorphism is a common, widespread type of metamorphism typically associated with mountain building where large segments of the crust are deformed by the collision of two colliding blocks" is True because regional metamorphism is a type of metamorphism that occurs in wide areas of the Earth's crust.

Regional metamorphism occurs mainly in areas with mountain-building activity where large segments of the Earth's crust are deformed by the collision of two blocks. Metamorphic rocks are formed when pre-existing rocks undergo profound changes in response to the influence of high temperature, high-pressure fluids, and the passage of time.

Regional metamorphism, in which rocks are subjected to high pressure and temperature, is one of the two types of metamorphism. The process results in the formation of metamorphic rocks. The high pressure and temperature lead to the development of crystals, and the compression of layers causes the rock to become denser.

Regional metamorphism is widespread and can occur in large areas of the Earth's crust, often associated with the formation of mountains. The other type of metamorphism is contact metamorphism. In contrast to regional metamorphism, it occurs only in small areas and is caused by heat from magma chambers or hot igneous bodies.

dramatic steps such as spraying aerosols into the stratosphere to reduce solar radiation or building large machines to draw carbon directly from ambient air are examples of what?

Answers

Dramatic steps such as spraying aerosols into the stratosphere to reduce solar radiation or building large machines to draw carbon directly from ambient air are examples of global engineering (geoengineering).

What is the meaning of global engineering?

This involves the extensive manipulation of a certain process that is essential to managing Earth's climate in order to get a particular benefit. The amount of solar radiation that Earth receives and how this energy is handled within the Earth system, namely how much of it is absorbed by the surface of the planet and how much is reflected or reradiated back into space, both affect global temperature.

Several factors, like as the albedo of the Earth's surface, the amount of clouds, and the presence of greenhouse gases like carbon dioxide in the atmosphere, affect how much solar radiation is reflected (CO2). Geoengineering projects must deliberately change the relative influence of one of these regulating systems if they are to have any significant impact on the global climate.

describe two soil conservation strategies that could be used to prevent soil erosion in agricultural fields that are established in this landscape.

Answers

You did not provide what "this landscape" is.

Answer:

1. Cover crops

2. Terracing

Explanation:

There are several soil conservation strategies that can be used to prevent soil erosion in agricultural fields. Two common strategies are:

1. Cover crops: Cover crops are plants that are grown in agricultural fields when they are not being used to grow crops for human consumption. These plants help to protect the soil by providing a protective layer of vegetation that can reduce the impact of rain and wind on the soil. Cover crops can also help to hold the soil in place and prevent it from washing or blowing away.

1. Terracing: Terracing is a technique in which agricultural fields are divided into a series of levels or tiers, with each level separated from the others by a series of raised ridges or walls. This helps to prevent erosion by slowing the flow of water down the slope of the field and allowing it to infiltrate the soil more gradually. Terracing can also help to prevent soil from being washed or blown away by wind, and it can help to preserve the soil's structure and fertility.

Both of these strategies can be effective at preventing soil erosion in agricultural fields, and they can be used alone or in combination with other soil conservation techniques. It is important to carefully consider the specific conditions of the field and the local environment when choosing which soil conservation strategies to use, in order to ensure that they are effective and sustainable.

The variable K in the logistic growth formula (orange) represents the carrying capacity of an ecosystem. Use the sliders in the simulation to determine how the carrying capacity affects the population over time.

Answers

The carrying capacity has a significant impact on the population over time. As the carrying capacity increases, the population grows at a faster rate until it reaches the new limit. However, if the population exceeds the carrying capacity, it will experience a decline due to the limited resources. On the other hand, if the carrying capacity decreases, the growth rate slows down, and the population may even decline. Thus, understanding the carrying capacity is crucial in managing and preserving the ecosystem's health and resources.

More than any other region, Sub-Saharan Africa is noted for its wildlife, especially large mammals. What environmental and historical processes explain the existence of so much fauna?

Answers

The environmental and historical processes that explain the great variety of fauna in Sub-Saharan Africa are, respectively, the formation of diverse environments and the isolation of the region.

Sub-Saharan Africa is home to a diverse array of fauna due to a combination of environmental and historical processes:

Environmentally, the region's diverse environments, ranging from savannas and grasslands to tropical rainforests and deserts, provide a wide range of habitats for different species to thrive. Additionally, the region's climate, which is generally warm and wet, promotes the growth of vegetation and supports a large number of herbivorous animals, which in turn support a large number of carnivorous animals.Historically, Sub-Saharan Africa has also been relatively isolated from other regions, allowing its fauna to evolve without significant competition from other species. The region's relative lack of human development has also allowed many animal species to survive without being hunted or having their habitats destroyed.

In summary, the combination of diverse environments, a favorable climate, relative isolation, and a lack of human development have all contributed to the abundance of fauna in Sub-Saharan Africa.
