Pumice floats on water because it has an incredibly low density due to the air bubbles inside of it. As it is blown out of a volcano (extrusive igneous), and dissolved gasses exsolve and more air gets into it before it hardens into pumice. The less dense air offsets the more dense rock, causing it to float.

Students want to determine the impact of soil erosion from the development of new housing. They plan to measure the density of a species of algae growing along the bottom of a river that flows through their town. The town is built in a heavily forested area, but a large area of trees along the river was recently clear-cut to allow for the construction of a new housing development, which has caused exposed soil to wash into the river. The river flows north to south through the town and is still forested both up- and downstream of the town. Which of the following would be the best control sample for the study?
a. A sample of water collected just downstream of the northern forest
b. A sample of water collected just downstream of the southern forest
c. A sample of distilled water
d. A sample of water collected just downstream of the housing development
Considering the situation described above, the statement that would be the best control sample for the study is "a sample of water collected just downstream of the northern forest."
The students want to measure the density of algae growing along the bottom of a river that flows through their town.
And given that the river flows north to south through the town, it is ideal for controlling the sample for the study through a sample of water collected just downstream of the northern forest.
Hence, in this case, it is concluded that the correct answer is option A.

These graphs show global temperatures (left) and carbon emissions (right) over time. The graph of global temperatures is based on
1951-1980 average temperatures, which was 14 degrees Celsius (57.2 degrees Fahrenheit). The data show how high or low Earth's
surface temperature was above that average (14 degrees Celsius). The Global Fossils Carbon Emissions graph shows annual carbon
dioxide emissions based on fuel type. Human activities such as fossil fuel combustion, cement production, and agriculture all
contribute to carbon emissions. Based on the data shown, what reasonable conclusion can be drawn?

A)
Global temperatures tend to increase as carbon emissions increase
B)
Global temperatures increase over time, regardless of human activity
Natural gas emissions have no effect on global temperature increases.
D)
The burning of coal has had the greatest effect on global temperatures.
According to the information, we can state that global temperatures tend to increase as carbon emissions increase, as shown in option A.
We can arrive at this answer because:
According to the information in the question, the increase in carbon emissions is one of the main factors responsible for the increase in global temperatures.This can be proven by observing the graph, where it is possible to see that there was a significant increase in global temperatures, as carbon emissions increased.These carbon emissions are the result of the increase in human activities and industrial processes, which promote the degradation of the atmospheric layers and allow an intense increase in global temperature.

plsssss helpppp im confused.....i dont know if the answer I chose is correct
Answer:
You chose the right answer! Chemical weathering degrades rocks and minerals; or breaks it down, instead of building it up!
Explanation:
The erosion or disintegration of rocks, building materials, etc., caused by chemical reactions (chiefly with water and substances dissolved in it) rather than by mechanical processes.
Examples on Chemical Weathering:
Some examples of chemical weathering are rust, which happens through oxidation and acid rain, caused from carbonic acid dissolves rocks. Other chemical weathering, such as dissolution, causes rocks and minerals to break down to form soil.

the Sun's involvement or role
any benefits or effects on Earth, life on Earth, and/or Earth's natural processes
Be creative!
Create your illustration using a computer program (such as Word, Paint, Power Point, Publisher, or any other you are familiar with) and upload it.

Answer:
So you have to choose one of those topics me personally would choose photosynthesis jsut because its something I remember and have done basically this task on before. You have to create something like a diagram/ illestration on it
For example you could do a diagram of the sun in the sky and a plant and how photosynthesis happens
Or the water circle so coukd draw a puddle and the sun and the water evaporating ( I think this is right and I hope this helps sorry if it dosent :))
Photosynthesis, involves the Sun's relationship with Earth. It was the natural process.
What is Earth radius?The term Earth refers to the planet of the solar system. The Earth is the only planet where life is possible for living things' in reason of gravitational force. The Earth's main elements are life, air, water, and land. The Earth's planet radius is 3,959 miles. The Earth is only for oxygen.
Photosynthesis is the primary function of the sun on earth. Because of this mechanism, life exists on Earth because plants use solar energy to make their food, which is then consumed by herbivores, maintaining the food chain.
As a result, the significance of the involves the Sun's relationship with Earth. It was the natural process are the aforementioned.

describe the main processes of water cycle
Answer:
water evaporates from the water bodies and forms clouds..then the clouds condense and finally precipitate in the form of rain,hail storms,snow etc..
hope it helps
Answer:
There are five processes at work in the hydrologic cycle: condensation, precipitation, infiltration, runoff, and evapotranspiration
Explanation:
The water cycle depicts the continual flow of water on Earth and in the atmosphere. It's a complex system with many separate processes. Liquid water evaporates into water vapour, condenses into clouds, and precipitates as rain and snow on the ground.
Evaporation, condensation, and precipitation are the three fundamental processes that make up the water cycle. Evaporation is the transformation of a liquid's surface to a gas.
Liquid water (from the ocean, lakes, or rivers) evaporates and turns into water vapour in the water cycle. Water vapour is a significant greenhouse gas as well. Evaporation, condensation, and precipitation are commonly taught as a simple circular cycle.
Evaporation, condensation, precipitation, interception, infiltration, percolation, transpiration, runoff, and storage are all processes that may be examined. When the physical condition of water changes from a liquid to a gaseous state, evaporation happens.
The water cycle is the course that all water takes as it passes through different phases across the Earth. Oceans, rivers, lakes, and even subterranean contain liquid water. The water cycle is the course taken by all water as it travels around our world.

Explain how wildlife (animals) can survive in a hot desert environment.
Some smaller desert animals burrow below the surface of the soil or sand to escape the high temperatures at the desert surface. These include many mammals, reptiles, insects and all the desert amphibians. Rodents may plug the entrances to their burrows to keep out hot, desiccating air.
Explanation:
Animals survive in deserts by living underground or resting in burrows during the heat of the day. Some animals get the moisture they need from their food, so they don’t need to drink much water.
