B. Newton
C. Copernicus
D. Brahe

Answers

Answer 1
Answer:

The answers are:

A. Ptolemy

B. it always casts a curved shadow during a lunar eclipse

C. Copernicus


Ptolemy believed that the Earth was the center of the universe. He refined the model of Plato. He proposed that the planet has a small orbit called an epicycle and it moves along the a larger orbit that goes around the Earth.


Aristotle was convinced that the Earth was round because a lunar eclipse is caused by the shadow of the Earth. The shadow is always circular.


Copernicus was the first to propose the heliocentric model. He described the movements of the planets using astronomical theories which proposed the sun was at the center and not the Earth.

How do changes in wind currents affect the short-term climate in a region? Prevailing winds can cause a milder climate with heavy rain. Global winds can cause a longer summer. Prevailing winds can cause heavy rains or a dry climate. Global winds can cause a longer winter.

Answers

Change in the winds currents.

The changes in the sea currents which affect the waters and the climate of the region. Thus the answer is prevailing currents created large rain. These events lead to the creation of the changes that lead to the formation of the weather changes.

  • As per the global winds patterns, the exchange of the pressure leads to the flow of winds in the said direction in addition to the spinning of the earth.
  • These prevailing winds are cause of heavy rains or the dry climate.
  • Thus the option C is right.

Answer:

Prevailing winds can cause heavy rains or a dry climate.

Explanation:

Wind currents bring significant changes in the climate of the place. It is the wind currents that shifts and communicate air from climate of one place to another. When warm winds blow over the area containing water, they carry the moisture from the place and shifts them to another place. When these winds reaches to cold place, they condense and falls as water droplets. In this way, the wind currents can cause change in the short-term climate in a region.

In general, where do volcanoes form in subduction zones?.

Answers

Volcanoes form in two situations: when an oceanic plate descends beneath another oceanic plate or when an oceanic plate descends beneath a continental plate. This process is known as subduction, and it results in different types of volcanoes depending on the location: An island-arc volcano is formed as a result of ocean-ocean subduction.

Final answer:

Volcanoes in subduction zones form on the overriding plate as the subducting plate sinks beneath it. The subduction process creates deep ocean trenches where magma rises to the surface, forming volcanic arcs and mountain ranges.

Explanation:

In subduction zones, volcanoes typically form on the overriding plate as the subducting plate sinks beneath it.

When the subducting plate bends and plunges into the mantle, it creates a deep ocean trench. As the oceanic crust subducts, it begins to melt due to high temperatures and pressure. The melted rock, or magma, is less dense than the surrounding mantle, causing it to rise to the surface and form volcanic arcs or mountain ranges.

Examples of volcanic arcs formed in subduction zones include the Andes in South America and the Cascades in North America.
