Where does the thermal energy to melt Earth's inner rock come from?
The thermal energy to melt Earth's inner rock comes from the initial collapse and formation of the planet, as well as from the radioactive decay of unstable elements within the Earth.
Explanation:The thermal energy to melt Earth's inner rock comes from two sources. Firstly, it comes from the initial collapse and formation of the planet, where gravitational potential energy is converted into thermal energy. Secondly, it comes from the radioactive decay of unstable elements within the Earth, such as uranium, thorium, and potassium. These radioactive decays release energy, which contributes to the Earth's molten interior.

The fertilizer could cause crops to release pollution into the air.
B.
The fertilizer could kill useful insects.
C.
The fertilizer could make the soil too fertile to grow crops.
D.

The fertilizer could runoff and pollute nearby water sources.
Explanation:
In the past several decades, the agriculture has changed significantly, as the methods for work, production, fertilization, have all changed in order to have maximum benefit. One of the most used things in the agriculture are the fertilizers, with their purpose being enriching the soil so that it can support more plants, and also to make them produce more in quantity. While in general this has good results when it comes to the crops, it also brings in some problems.
One of the most common problems is that the fertilizers runoff or wash through, and manage to get to the nearby water bodies. They over saturate the water with nutrients, causing eutrophication. This causes large scale growth of weeds and algae, and the algae rapidly cover the surface of the water body, blocking the sunlight, and extracting the dissolved oxygen from the water, thus systematically killing of the other organisms.

To use remote sensing correctly, a geographer needs to be physically at the place of study.
Answer:
yes
Explanation:
A geographer does not need to be physically present to use remote sensing, which is a method of collecting data from a distance using aerial platforms. This technique is valuable for analyzing the Earth's surface and tracking changes, but it should be complemented by field data for verification.
To address the student's question directly, remote sensing does not require a geographer to be physically present at the location being studied. Instead, remote sensing refers to the technique of acquiring data about the Earth's surface through the use of aerial platforms such as satellites, airplanes, or drones. This allows geographers to collect data and analyze various aspects of an area from a distance.
Remote sensing is particularly valuable because it provides imagery and information about the physical and human characteristics of a place, such as land use and landscape changes, which can be especially useful in inaccessible or vast areas. It leverages the interaction between earth materials and the electromagnetic spectrum, extending our capabilities to see beyond the visible range. For example, analyzing different wavelengths can help identify vegetated areas using the infrared spectrum.
However, it is important to mention that remote sensing serves as a complement rather than a replacement for traditional field studies. For the data obtained to be considered reliable, it often needs verification through field data collection. While remote sensing offers a broad view and can track changes over time, field verification helps ensure accuracy and provides a more detailed analysis at the ground level.
Production was often inefficient under communist rule because people
Answer:
The correct response is "people had little incentive to work efficiently."
Explanation:
Scholars who critique the communist model of society often stress how it lacks the competitiveness that is inherent to a free market system. Workers in a communist system join unions that are ultimately controlled by the state where wages are set by the government and there is little differential between different skills and talents. Thus the worker in a communist system has little incentive to perform better than their peers or to aspire to a higher position in terms of their employment following this logic.

Given that 10m = 14n , find the ration of m:n in simplist from
Answer:
5:7
Explanation:
You divide both sides by the same number to find the least common multiple. ex) 10 and 14 are both divisible by 2.
10÷2=5
14÷2=7
Therefore 5m = 7n
Final answer:
Given that 10m = 14n, the ratio of m to n in simplest form is 7:5, after dividing both terms by their greatest common divisor, which is 2.
Explanation:
To find the ratio of m to n in simplest form given that 10m = 14n, we first rewrite the equation in the form of a ratio:
m/n = 14/10
Now we simplify the ratio by dividing both the numerator and the denominator by their greatest common divisor, which is 2:
m/n = 7/5
Therefore, the simplest form of the ratio m:n is 7:5.

after 2004, Polish exports increased when _____.
After 2004, Polish exports increased after the country entered the European Union.
Explanation:
Poland, as multiple other countries of Central and Eastern Europe, has communist past. When the communism fell, Poland struggled for some time, as the country needed to change a lot in its functioning, especially the economy and the development of relations with other countries. Despite the country doing everything right, it was still not able to reach its potential because of the limitations.

Two angle sare supplementary. One angle measures 75° more than twice the measure of the other. What are the measurements of the two angles?
Answer:
The measurements of two angles are 40 and 140
Explanation:
Let's call the angles as x and y.
We know that supplementary angles must add to 180 degrees,
so, x+y=180. ---------(i)
Furthermore, we know that x is 75% more than 2 y.
We can write "75% more than" numerically as 1.75,
so x = 1.75(2 y).
We can simplify the second equation by multiplying
[tex]1.75 \times 2[/tex]
x = 3.5 y.
Now we can solve the system of equations by substitution by plugging
3.5y in for x in
x+y=180.
(3.5 y) + y = 180
Combine like terms.
4.5 y = 180
y =[tex]\frac{180}{4.5}[/tex]
y = 40
Putting the value of y = 40 in equation (i) and calculating the value of x
x + 40 = 180
x = 140
The answer is 40 and 140.
Therefore, the measurements of two angles are 40 and 140

The evolution of photosynthetic life led to an increase in atmospheric oxygen, reduction in CO2 levels, and the formation of an ozone layer, which allowed for more complex life forms to evolve on Earth.
Explanation:The evolution of photosynthetic life forms, such as cyanobacteria, dramatically altered Earth's atmosphere. Initially, the atmosphere was anoxic, containing no molecular oxygen, and only anaerobic organisms could live. However, once photosynthesis began, these organisms released oxygen as a by-product. Over time, the accumulation of oxygen led to significant changes, including the development of an ozone layer that protects living organisms from harmful ultraviolet radiation, allowing for more diverse and complex life forms to evolve.
Furthermore, the process of photosynthesis involved the consumption of carbon dioxide, which reduced the atmospheric levels of CO2 and led to the deposition of carbon in marine sediments. This contrasted greatly with planets like Venus and Mars, which ended up with atmospheres dominated by carbon dioxide. On Earth, thanks to photosynthetic life, we now have an atmosphere rich in nitrogen and the unique presence of free oxygen.

Describe negative effects of climate change
The climate change is a natural process, lately helped by the human activity, which can have numerous negative and positive effects.
Explanation:
The climate change is a natural process that has been present on the planet for hundreds of millions of years. In the past few decades it is often stated that the humans with their activity have big influence on this process, but that is not true, as the influence is minimal, at least for now. The climate change can go either way, it can be global cooling (Ice Age) or global warming.
It seems that in the present we are facing with global warming. The global warming can have multiple effects, both positive and negative. The negative ones are that the climate will become more unpredictable. Some places will experience longer droughts, while some intense rainfalls. The storms will be becoming more powerful as the sea level rises. The rise of the sea level will submerge the most populated areas on the planet, thus a mass migration toward the interior will be needed.

Which of these processes describes the effect Earths atmosphere has on Earths hydrosphere
C.
Warm, moist air in the atmosphere causes an increase in ocean temperatures. This is one processes that describes the effect Earth's atmosphere has on Earths hydrosphere.
Explanation:
When the atmosphere is warm, this heat is transferred to the oceans by conduction - because the two systems are not isolated from each other they share matter and energy. The warmer the atmosphere the warmer the oceans become. Moist air also means that the atmosphere cannot accommodate as much more moisture. Therefore oceans cannot lose much heat by evaporation. Collectively, warm moist air causes a significant rise in ocean temperatures.

Answer: There are many different types of precipitation —rain, snow, hail, and sleet for example—yet they all have a few things in common. They all come from clouds. They are all forms of water that fall from the sky.
Explanation:
The four main forms of precipitation are rain, snow, sleet, and hail. Each is the result of specific atmospheric conditions and temperature variations.
Explanation:The four main forms of precipitation are rain, snow, sleet, and hail. Rain occurs when water droplets in clouds become too large and heavy, causing them to fall to the ground. Snow is formed when cold temperatures freeze this water vapor into ice crystals. As for sleet, it happens when raindrops pass through a layer of cold air and freeze before hitting the ground. Finally, hail form in severe thunderstorms when updrafts carry raindrops upward into extremely cold areas of the atmosphere where they freeze and accumulate layers of ice before falling to the ground.
