Which part of the earth is responsible for generating the planet's magnetic field?

Answers

Answer 1

Answer:

The magtnetic feild is generated by eletric currents due to the motion of convection currents of the molten iron in the Earths outer core. These convection currents are caused by heat escaping from the core, a natural process called a geodynamo.

Explanation:

Answer 2

Earth's magnetic field is generated by the movements of molten metals in its liquid outer core. These movements produce electric currents through the dynamo effect, creating a magnetic field that shields the planet from harmful solar wind and cosmic radiation.

The Earth's magnetic field is critically important for life on Earth. Here's a detailed explanation:

Outer Core: The primary source of Earth's magnetic field is the liquid outer core, primarily composed of molten iron and nickel. The movement of these molten metals generates powerful electric currents.Thermal and Compositional Currents: Within the liquid outer core, thermal and compositional currents arise due to temperature and pressure differences. When coupled with the Earth's rotation, these currents produce the geomagnetic field.Dynamo Effect: The process responsible for generating the magnetic field is called the dynamo effect. This involves the motion of the liquid metal that creates and maintains the magnetic field.Protection from Solar Wind: The magnetic field plays a vital role in shielding Earth from the solar wind, a stream of charged particles from the sun that can strip away the atmosphere and harm life by allowing harmful ultraviolet rays.Magnetosphere: The region enveloped by Earth's magnetic field, known as the magnetosphere, further extends thousands of kilometers into space, providing additional protection from cosmic radiation.

In summary, the dynamic movements of molten metals in the Earth's liquid outer core, driven by thermal and compositional currents and the Earth's rotation, are responsible for generating and maintaining the planet's magnetic field.

What was "manifest destiny"? Question 12 options: Mexican belief that it was meant to be independent from Spain doctrine that the US had the right and duty to expand throughout North America Canadian doctrine that supported elimination of most Native American tribes American belief in the natural goodness of all colonists

Answers

Final answer:

Manifest Destiny was the 19th-century belief that the US was destined to expand across North America, a doctrine that gained momentum in the 1840s leading to the annexation of territories like Texas and California.

Explanation:

The term "Manifest Destiny" referred to the widely held 19th-century belief and doctrine that it was the destiny and duty of the United States to expand its territory across North America. Proponents argued that this expansion was preordained, just, and reflected a mission to spread democracy and freedom "from sea to shining sea". The movement for expansion gained significant momentum in the 1840s, incorporating regions such as Texas and Oregon into the Union. It was also a leading cause of the war with Mexico, leading to the acquisition of territories like California. During this process, Americanization of the local inhabitants, including Native American tribes and Mexicans, was considered a natural progression, often overlooking the complex realities of the existing societies and the means through which territories were acquired.

Describe how you plan to construct your geologic column for the grand canyon canyon.

Answers

Final answer:

Constructing a geologic column for the Grand Canyon involves studying and documenting each layer of rock from the bottom to the top of the canyon, noting the type of rock and any fossils. This process represents time, with each layer equating to a specific geologic era.

Explanation:

To construct your geologic column for the Grand Canyon, you would need to start by comprehensively studying and documenting the different rock layers. The Grand Canyon's geologic column is unique and vast, comparable in size to a canyon system stretching from Los Angeles to Washington, DC.

Begin at the bottom of the canyon, with the oldest rock layers – the Vishnu Basement Rocks, and gradually move upward through each distinct strata, noting the type of rocks and any visible fossils. This can include the Supai Group, Redwall Limestone, or the igneous and metamorphic rocks found in areas such as the Zoroaster Granite.

The final step would be to compile your findings into a detailed report, effectively producing your geologic column. Do remember that the process of constructing a geologic column is a representation of time, with each layer equating to a specific geologic era.

What causes the northern and southern halves of the planet to experience winter and summer at opposite times?A) the tilt of Earth B) Earth’s daily rotation C) the gravitational pull of the moon D) the distance of Earth from the sun

Answers

Answer:

a. the tilt of the earth

Explanation:

The Northern and Southern Hemisphere experience different seasons at opposite times because of the tilt of the Earth's axis.

The tilt of Earth causes the northern and southern halves of the planet to experience winter and summer at opposite times. The correct option is A.

What are the northern and southern halves of the Earth called?

The hemispheres, which are formed when a circle is traced around the Earth, are equally sized. Generally speaking, there are four hemispheres: the northern, southern, eastern, and western. The Northern and Southern Hemispheres of the Earth are separated by the Equator, sometimes known as the line of 0 degrees latitude.

The tilt of Earth's axis causes the northern and southern hemispheres to be oriented towards or away from the sun at different angles throughout the year. This causes the amount of sunlight and heat received by each hemisphere to vary, resulting in the opposite seasons.

When the northern hemisphere is tilted towards the sun, it experiences summer, while the southern hemisphere is tilted away from the sun and experiences winter. When the northern hemisphere is tilted away from the sun, it experiences winter, while the southern hemisphere is tilted towards the sun and experiences summer.

Thus, the ideal selection is option A.

The explanation:

- Alps's mountain chains was the only one which not created by subduction, because Alps formed by collision. The collision is a geologic process in which two plates collide each other, in our example(Alps formation) the Africa tectonic plates collide with the Eurasian tectonic plates and  uplift the crust of the earth  forming the mountain chains.

- but the subduction is a geologic process happened in the regions called subduction zone when one tectonic plate is go under another tectonic plate.

So Alps wasn't created by subduction , but formed by collision.
