They based their idea of continental drift on several lines of evidence: fit of the continents, paleoclimate indicators, truncated geologic features, and fossils.

Continental go with the flow is the hypothesis that the Earth's continents have moved over geologic time relative to each other, as a result acting to have "drifted" across the sea bed. The idea of continental go with the flow has been subsumed into the science of plate tectonics, which researches the movement of the continents as they experience on plates of the Earth's lithosphere.

The speculation that continents might have 'drifted' was first put forward by way of Abraham Ortelius in 1596. A pioneer of the modern-day view of mobilism turned into the Austrian geologist Otto Ampferer. The concept changed independently and extra completely developed by Alfred Wegener in 1912, but the speculation changed into rejected by using many for loss of any cause mechanism.

Answer: Earth would become an ice-cold planet without the sun's heat and light.

Explanation:

Without the sun's heat photosynthesis would not take place in plants. The temperature of the Earth would drop and it would not be a liveable place for numerous plant and animal species. Humans would cease to exist. The top layers of the oceans would be frozen.

Although the frozen top layers of the oceans would insulate the deep waters below, keeping them liquid for hundreds of thousands of years, they would eventually freeze as Earth moved toward a stable average global surface temperature of about -400º F. At that point, the atmosphere would have also frozen and fallen to Earth, leaving anyone left alive exposed to the harsh cosmic radiation that travels through space.

Without the light of the sun, there would be complete darkness on the surface of the Earth.

Phosphorus repositories are tracked down fundamentally in soil and sedimentary rocks, in light of the fact that dissimilar to different supplements that cycle through the biosphere, phosphorus can't be tracked down in that frame of mind in the vaporous state.

Phosphorus moves in a cycle through rocks, water, soil and silt, and creatures. Over the long haul, downpours and enduring reason rocks to deliver phosphate particles and different minerals. This inorganic phosphate is then appropriated in soils and water. Phosphorus can be tracked down on earth in water, soil, and dregs. Dissimilar to the mixtures of other matter cycles phosphorus can't be tracked down in the air in the vaporous state. This is on the grounds that phosphorus is typically fluid at ordinary temperatures and tensions. It is basically going through water, soil, and silt.

To determine the relative ages of the rocks, the geologist use: the law of superposition. The correct answer is option C.

Law of superposition, a major principle of stratigraphy stating that within a sequence of layers of sedimentary rock, the oldest layer is at the base and that the layers are progressively younger with ascending order in the sequence.

An example would be that the silt back-fill of an underground drain would form sometime after the ground immediately above it. Other examples of non-vertical superposition would be modifications to standing structures such as the creation of new doors and windows in a wall.

Although part of your question is missing, you might be referring to this full question: A geologist is studying three layers of sedimentary rock in an area. The layers have not shifted from their original positions. The geologist records the relative ages of the rocks. The bottom layer is listed as the oldest. The top layer is listed as the youngest.

African slavery expanded in the 17th century for a number of reasons. One of the main factors was the increasing demand for labor in the New World, particularly in the Caribbean and in the colonies of North and South America. As these regions were colonized and developed, there was a need for a large, reliable source of labor to work on plantations, mines, and other forms of economic development.

At the same time, there was a declining supply of indentured servants in Europe, as conditions improved and the population grew. This meant that plantation owners and other employers in the New World were forced to look for other sources of labour. African slaves were seen as an attractive alternative, as they were believed to be stronger and more resistant to disease than European indentured servants. They were also more readily available, as the transatlantic slave trade was already well established by this time.

Another factor that contributed to the expansion of African slavery in the 17th century was the increasing demand for luxury goods, such as sugar, tobacco, and cotton, which were produced on plantations in the New World. The demand for these goods was fueled by the growth of European economies, particularly in England and France, which became major consumers of these products. To meet this demand, plantation owners needed to expand production, which required a larger and more reliable source of labour. African slaves were seen as an ideal source of labour, as they could be coerced and controlled more easily than European indentured servants.

Finally, the expansion of African slavery in the 17th century was also facilitated by the development of legal and institutional frameworks that supported the trade and exploitation of slaves. European powers such as Portugal, Spain, and England established laws and policies that supported the enslavement and exploitation of Africans, and they also provided economic incentives to encourage the trade. These legal and institutional frameworks helped to create a profitable and sustainable system of African slavery that persisted for many centuries.

Overall, the expansion of African slavery in the 17th century was driven by a combination of economic, demographic, and legal factors. The increasing demand for labour in the New World, the declining supply of indentured servants in Europe, the growing demand for luxury goods, and the development of legal and institutional frameworks that supported the trade and exploitation of slaves all contributed to the expansion of African slavery during this period.

It restricts freedom.

It may ignore societal needs.

It slows down innovative developments.

It causes black markets to explode.

It offers no competition.

Explanation:

1. It restricts freedom.

Due to the fact that this type of economic system is tied to communist countries, it is no surprise that it also takes the freedom away from the people and puts full control in the hands of the government alone. People can not choose their careers based on their skills and interests; rather, it is based upon what the government forces them to do. All jobs are aligned with needs at a time, and people have little freedom of choice. This major downside to a command economy can lead to discontented citizens.

2. It may ignore societal needs.

Command economy often ignores the needs of the society for its betterment. Workers will not be given the options on where they can work or where they can move.

3. It slows down innovative developments.

Unlike a free market that encourages change and innovation, a command economy does not offer this advantage. Since the government controls the market, it does not make innovation a priority or does not encourage it all in all. This is because it controls all aspects of production and leaves no room for people to make it better, leading to a workforce that is less motivated to create higher-quality products or services.

4. It causes black markets to explode.

Because of restrictions by the government, some products and services are not offered in the command economy, so they would be offered on black markets.

5. It offers no competition.

Competition on the market is one of the main forces of improvement, but in a command economy, there is little competition. The government owns all the industries and does not encourage competition or actually exerts effort to eliminate it. The benefits gained from competition are not seen in this type of market.

The collection of subatomic particles known as leptons, which are thought to be fundamental or elementary particles, includes electrons in its description of particle physics. A chemical element is uniquely defined by its atoms, which are tiny pieces of substance. A negatively charged electron or electrons surround the nucleus. The positively charged, comparatively hefty protons and neutrons that make up the nucleus may be present. In the list of statements, the statement that most accurately defines an electron is that it lives in the nucleus.
