1. Which result from the Interaction of solar weather on Earth’s magnetic field?
A. Geomagnetic storms and B. Auroras.
Explanation:
Reactions that occur on the surface of the Sun are known as solar or space weather. These reactions usually affect our planet differently, mainly to the Earth's magnetic field that serves as a shield for the earth.
A geomagnetic storm occurs when the solar wind collides with the electromagnetic field of the earth generating disturbances in the Earth's magnetosphere.
An aurora is a luminescent formation produced by the interaction of charged solar particles and the terrestrial electromagnetic field. The solar wind pushes these particular to the terrestrial electromagnetic field that later transports them to the poles, where they are seen in different colors according to the type of particle.
2. The sun’s energy is generated in its
D. Core.
Explanation:
The energy emitted by the sun comes from the core. In the core the hydrogen atoms are converted to helium through Nuclear fusion, this process causes the core to heat up to 17 million degrees Fahrenheit. These particles later go up to the photosphere where they produce light and heat and then are expelled into space.
3. How does nuclear fusion make life on Earth possible?
B.releases energy that warms Earth.
Explanation:
Nuclear fission occurs when the hydrogen nuclei under the great gravity of the sun merge into a heavier nucleus, in helium, this releases a large amount of energy; This energy is expelled from the sun into space. On earth, we perceive these particles as light and heat and due to this process, the earth has a suitable temperature for life.
4. During the low point in the sun’s 11-year cycle, the___ gravitational magnetic, radiative or electric field lines up with the poles,resulting in___ more or fewer . At the peak of the solar cycle,__ more or fewer sunspots tend to form.During that phrase of the solar cycle,intense bursts of radiation cause__sunspots or solar flares or solar eclipses.This often occurs with coronal mass ejections, which are magnetic projections or eruptions of huge amounts of plasma from the sun.
During the low point in the sun’s 11-year cycle, the field lines up with the poles, resulting in sunspots. At the peak of the solar cycle, more sunspots tend to form. During that phrase of the solar cycle, intense bursts of radiation cause solar flares. This often occurs with coronal mass ejections, which are eruptions of huge amounts of plasma from the sun.
Explanation:
Solar cycles are periods of 11 years in duration that regulate the activity of the sun.
During a cycle, the sun reaches the maximum solar (the period of greatest activity) every 11 years due to the process carried out by its magnetic field and how it controls the solar plasma. During the solar maximum, coronal loops are created and are ejected from the sun in large flares that can be studied from the earth.
5. Over the past 100 years,Earth’s temperature has increased about 1.1F or 2.4 F . Solar heating due to space weather is responsible for about ___ 25% or 50%
Over the past 100 years,Earth’s temperature has increased about 1.1F. Solar heating due to space weather is responsible for about 25%.
Explanation:
Temperature is the measure by which the heat in the Earth's atmosphere is evaluated using measuring instruments. The terrestrial temperature usually varies through the years due to different processes, and throughout the terrestrial history, we have the temperature has been higher or colder.
We are currently going through a period of global warming, in part due to space weather, and in part due to increased greenhouse gases in the atmosphere that prevent the sun's heat particles from leaving the Earth's surface.
6. Which are predicted to happen in the case of a severe geomagnetic storm?
B. Signals from radio navigation systems will be disrupted and be inaccurate.
D. High-frequency radio waves used for radio communications will be blocked.
Explanation:
An electrical storm occurs when the solar wind collides with the Earth's electromagnetic field and generates disturbances in the magnetosphere. These storms can be mild or severe, and they have various effects.
One of the effects of disturbances occurs in radio waves because the magnetosphere is affected, radio waves do not work properly, artificial satellites in space are also affected, mainly telecommunications satellites, that is why that the GPS would not work correctly.
