Which of the following events could increase Earth's temperature?
Question 2 options:
A. a decrease in the relative percent of greenhouse gases
B. planting more trees
C. widespread removal of tropical forests
D. a reduction in the use of fossil fuels
Answer:
The answer is C & A.
Hope this helped you out!^^
Temperature measures the average kinetic energy of particles of the substances. Therefore, the correct option is option C that is widespread removal of tropical forests.
What is temperature?Temperature is used to measure degree or intensity of heat of a particular substance. Temperature is measured by an instrument called thermometer.
Temperature can be measured in degree Celsius °c, Kelvin k or in Fahrenheit. Temperature is a physical quantity. Heat always flow from higher temperature source to lower temperature source.
We can convert these units of temperature into one another. The relationship between degree Celsius and Fahrenheit can be expressed as:
°C={5(°F-32)}÷9
A decrease in the relative percent of greenhouse gases, planting more trees and a reduction in the use of fossil fuels will decrease the temperature of the earth. Widespread removal of tropical forests increase the temperature of earth.
Therefore, the correct option is option C that is widespread removal of tropical forests.

How does a balanced chemical equation prove the Law of Conservation of matter?
Answer:
Every chemical equation follows to the law of conservation of mass, which states that matter cannot be created or destroyed. When you have an equal number of atoms of an element is present on both sides of a chemical equation, the equation is balanced therefore it is following the law of conservation of mass.
Explanation:
Answer:
A balanced chemical proves the Law of Conservation of Matter because the law stats that matter cannot be created nor destroyed. so, in every chemical reaction the amount of matter will stay the same in the product as it did in the reactant.
In other words, balanced chem equations show that mass in conserved in chemical reactions

How do water, wind, and thermal energy from the sun move about the earth's surface?
Molecules move more quickly because the sun's light energy transforms into heat energy on the planet. While cooler polar air and water travel away from the poles and towards the equator, warm air and water molecules rise and move in the opposite direction.
What is light energy ?The capacity to make different forms of light visible to human sight makes light energy a sort of kinetic energy. Light is referred to as an electromagnetic radiation that is produced by hot things like the sun, lasers, and lightbulbs. Photons, which are tiny energy packets, are present in light.
Water temperature, biological activities and plant photosynthesis and development are all impacted by light energy.
The air is heated by the sun, and warm air rises. The colder air from the surroundings is forced to enter to replace the rising heated air. The result of this is the wind. Ocean currents function similarly.
Thus, Molecules move more quickly because the sun's light energy transforms into heat energy on the planet.

How is a lunar eclipse similar to a solar eclipse? How are they different?
Answer:
they moon and sun are a factor in both of them
Explanation:
Answer:
From our perspective on Earth, two types of eclipses occur: lunar, the blocking of the Moon by Earth's shadow, and solar, the obstruction of the Sun by the Moon. When the Moon passes between Sun and Earth, the lunar shadow is seen as a solar eclipse on Earth. Also they are similar by An eclipse occurs when one celestial object obscures another celestial object. In the case of a solar eclipse, the moon moves between the Earth and the sun, thus obscuring the sun. A lunar eclipse occurs when the Earth moves directly between the sun and the moon. Either type of eclipse can be total or partial.
