Magma in the Earth's mantle moves in convection currents. The hot core heats the material above it, causing it to rise toward the crust, where it cools. The heat comes from the intense pressure on the rock, combined with the energy released from natural radioactive decay of elements.
Let's take water: it definitely has three forms: ice, liquid and water vapor: it's definitely the correct answer!
Wind is just movement of air, so it can't be in any other state.
And as far as air and soil are concerned: some parts of them can also appear in three states, but not the air or soil generally, for example water is included in both of them and it can appear in the three states!
<u>Answer:</u>
D. Preventing people from visiting wildfire-prone areas
This would cause the greatest reduction of wildfires
<u>Explanation:</u>
Anthropogenic activities are the main source for forest fires. Humans intentionally or unintentionally became the reason for forest fires than lightning, rainfall deficit, and wind speed. Forest people responsible for causing fires because of shifting cultivation and livelihoods. Sub tropical forest were fired for cattle rearing becuase dense forests are not fit for cattle rearing. Increase in lightning storm also causes the forest fire. Decrease in rainfall leads to forest fire in Equator and tropical regions because of high temperature and high wind speed.
Answer: Endogenic systems arise from forces within the Earth, while exogenic systems arise from forces above the Earth's surface
Explanation: Endogenic systems or factors are those that, by their own power, cause processes and actions within the Earth. Exogenic systems are those that by their forces cause processes and actions above the surface and on the surface of the Earth.
Exogenous systems are driven primarily by solar energy, as well as by all forces generated by the action of solar energy, and consequently by the energy of the moon, etc. So, for example, soil erosion is caused by the influence of wind force, then the tide is influenced by the force of the moon, snow, weathering, running water, etc.
Endogenous systems are caused by forces originating from the depths of the Earth. Thus, slow and sudden movements of parts of the Earth's mass below the surface can be induced. For example, volcanoes and earthquakes are sudden movements, while slow movements are tectonic plate movements that contribute to land formation. Slow movements can be horizontal, those that contribute to the formation of mountains, and vertical that contribute to the formation, primarily changes in continental building.
Push factors may include conflict, drought, famine, or extreme religious activity. Poor economic activity and lack of job opportunities are also strong push factors for migration.
Unemployment. Often, people leave places where they are less likely to get employment (such as rural areas) and go to urban areas where job opportunities are more plentiful. This factor has been the major reasons cities and towns are highly populated. Individuals leave their homes to search for employment in more industrialized areas.
Insecurity. People move away from places that experience terrorism, violence, and high levels of crime. They move in search of peaceful and secure environment.
Scarcity of land. People are forced to migrate in search of more land to cultivate and live in. Individuals in need of undertaking extensive agriculture move to less populated areas.
Political instability. The effects of politics force people to move out of their homes or even countries, in search of a peaceful environment.
Drought and famine. Some communities are nomads in that they move away from their land in periods of severe drought and famine in search of water and food.
Hope this helps:)
