continental drift was first proposed by a scientist named alfred . he theorized that the were once one large landmass that drifted apart very slowly over a long time.

Answers

Answer 1

Answer: large-scale horizontal movements of continents relative to one another and to the ocean basins during one or more episodes of geologic time. This concept was an important precursor to the development of the theory of plate tectonics, which incorporates it.The idea of a large-scale displacement of continents has a long history. Noting the apparent fit of the bulge of eastern South America into the bight of Africa, the German naturalist Alexander von Humboldt theorized about 1800 that the lands bordering the Atlantic Ocean had once been joined. Some 50 years later, Antonio Snider-Pellegrini, a French scientist, argued that the presence of identical fossil plants in both North American and European coal deposits could be explained if the two continents had formerly been connected, a relationship otherwise difficult to account for. In 1908 Frank B. Taylor of the United States invoked the notion of continental collision to explain the formation of some of the world’s mountain ranges.

= -0.15

θ =

500 word essay on , What is the theory of plate tectonics ? PLEASEEEEEE

Answers

Answer:

Plate tectonics is a scientific theory that explains how major landforms are created as a result of Earth’s subterranean movements. The theory, which solidified in the 1960s, transformed the earth sciences by explaining many phenomena, including mountain building events, volcanoes, and earthquakes.

It states that Earth's outer shell is made up of many different plates, all which glide over top the Earth's mantle. The plates are found in the lithosphere. Also known as continental drift, the theory of plate tectonics is the reasoning behind why and how continents are constantly moving.

During the 1950s and early 1960s, scientists set up seismograph networks to see if enemy nations were testing atomic bombs. These seismographs also recorded all of the earthquakes around the planet. The seismic records could be used to locate an earthquake’s epicenter, the point on Earth’s surface directly above the place where the earthquake occurs.

under florida law, when entering a no wake area, what action must a boater take?

Answers

If you see a no wake sign, it's time to wake up and power down. ... This is when you should be off plane and completely settled in the water, so that a wake, if any, created by your vessel is minimal at most.

State and federal regulations typically mandate that the captain follow the slowest vessel speed necessary to preserve steerage, but no faster than 5 MPH, when sailing through a no wake zone. The objective is to reduce the wake that boats traveling through the area make.

What is a no-wake area in Florida?

A vessel must operate in the "Idle Speed - No Wake" zone at a speed that is no faster than that required to maintain steerage and headway. At this speed, the vessel shouldn't create any wake. In areas designated by official "Idle Speed, No Wake" canal markers, it is forbidden to operate any motorboat faster than no wake speed.

Any boat moving in a zone marked "Idle Speed - No Wake" needs to move at a speed that allows it to maintain headway and steerageway. Any boat moving through a zone marked "Slow Down - Minimum Wake" needs to be totally off the aircraft and anchored to the ground.

Which statement is NOT true about the December solstice?
It is the day with the longest daylight in the Southern Hemisphere.
The subsolar point is over the Tropic of Capricorn.
Daylight hours get longer as one travels northward.
O It is summer in the Antarctic

Answers

Considering the options available, the statement NOT true about the December solstice is that "Daylight hours get longer as one travels northward."

This is evident in the fact that, during this period, that is when the North Pole is tilted furthest away from the Sun.

Also, December Solstice is characterized by the longest daylight in the Southern Hemisphere.

It is also the period when the subsolar point is over the Tropic of Capricorn.

And it causes summer in the Antarctic.

In 2021, the December Solstice will occur on the 21st of December.

Hence, in this case, it is concluded that the December Solstice is one of the unique days of the year.

In a paragraph of 3–5 sentences, describe how women worked to reform society during the Progressive Era

Answers

Answer:

In addition to the goals of combating political corruption, safety of working conditions, honourable and efficient city authorities, the Progressive Era was also a time of the women's movement that had a strong influence on the reforms and the course of that era. Due to the growth of production and business during the Industrial Revolutions, many jobs were created for women, which again created a middle class women throughout the American nation. These were women who took an active part in the implementation of social reforms during the Progressive Era. As women were massively involved in production, more free time was created at home for middle-class women. Women were involved in the struggle for emancipation as well as for the education of middle class women. The right to vote and, above all, women's main activity was to change the outdated Victorian view that women were inferior to men. So the main role of women in the progressive social reforms of the Progressive Era was to redefine the role and position of women in society.

Explanation:

Women were finding their place in America. They sought to advocate for their rights, including the right to vote. Women were also trying to influence moral reforms. Rapid growth in cities led to issues that worsened problems like poverty and unhealthy conditions. Women’s groups attempted to solve problems created by urbanization and industrialization through the temperance movement.

The temperance movement was a social movement that sought to improve family life by discouraging drinking alcohol. Drinking was blamed for social ills and keeping families in poverty. Moral reformers thought that alcohol restriction would make prisons and mental asylums unneeded. Groups like the Women’s Christian Temperance Union (WCTU) formed to combat the ills of alcohol. The WCTU advocated for laws against the consumption of alcohol. Carrie Nation, an extreme advocate of temperance, used a hatchet to smash bottles and barrels in saloons in an effort to curb alcohol consumption.

Choose a way to delnonstrate that you understand how the plates of Earth's
surface are able to move. Be sure to include these words: convection currents,
asthenosphere, divergent plate boundary

Answers

Answer:Rates of motions of the major plates range from less than 1 cm/y to over 10 cm/y. The Pacific Plate is the fastest at over 10 cm/y in some areas, followed by the Australian and Nazca Plates. The North American Plate is one of the slowest, averaging around 1 cm/y in the south up to almost 4 cm/y in the north.

Plates move as rigid bodies, so it may seem surprising that the North American Plate can be moving at different rates in different places. The explanation is that plates move in a rotational manner. The North American Plate, for example, rotates counter-clockwise; the Eurasian Plate rotates clockwise.

Boundaries between the plates are of three types: divergent (i.e., moving apart), convergent (i.e., moving together), and transform (moving side by side). Before we talk about processes at plate boundaries, it’s important to point out that there are never gaps between plates. The plates are made up of crust and the lithospheric part of the mantle (Figure 10.17), and even though they are moving all the time, and in different directions, there is never a significant amount of space between them. Plates are thought to move along the lithosphere-asthenosphere boundary, as the asthenosphere is the zone of partial melting. It is assumed that the relative lack of strength of the partial melting zone facilitates the sliding of the lithospheric plates.
