Answer:
it includes the decomposition and disintegration of rocks in "situ"
define folding and briefly explain the process of folding
Folding corresponds to a shift in tectonic plates, which move causing a change in the shape of rocks.
How does the folding process take place?Tectonic plates receive forces that compress them at the edges of the converging plates, which causes folding, which causes rocks to bend rather than break.
Therefore, the folding process can be observed through the change in rock formations, altering the structure of the rocks and the landscape of the reliefs.

Which dating method would be MOST appropriate for establishing the age of a sedimentary rock layer from an early hominid site in eastern Africa
potassium-argon dating of volcanic rocks provides very accurate ages for many East African Rift Valley hominid sites.
Potassium-Argon Dating is a method of determining rock formation time by measuring the ratio of radioactive argon to radioactive potassium in the rock. This dating method is based on the decay of radioactive potassium-40 into radioactive argon-40 in minerals and rocks. Potassium-40 is also broken down into calcium-40.
The potassium-argon (K-Ar) isotope dating method is especially useful for dating lava. It was developed in the 1950s and was important for the development of plate tectonics theory and the calibration of geological time scales.
K-Ar dating Accurate dating from 4.3 billion years (age of the earth) to about 100,000 years ago. During 100,000 years, only 0.0053% of potassium-40 in rocks decayed to argon-40, pushing the limits of today's detectors.

O C.
-5q2 + 262 + 8ab
- 36
O D.
-5a2 + 4ab
36
Answer:
D
Explanation:
you have to make groupes.
start with a² part and forget the rest from example.
-4a²-a²=? Now remember - and - is adding up. so -5a², which takes out options a and b, as there are 3a² instead of 5.
now let's take ab part and forge the rest.
-2ab+6ab=? that gives us 4ab. So option c, which says 8ab, is wrong. the last number isn't really important in this case because you've already seen the rest can't be.

Adams town, the main agreement on the islet, lies within the stormy receptacle. Polynesian islands Pitcairn is accessible only by boat through Bounty Bay, due to the islet's steep escarpment.
Henderson Island, covering about 86 percentage of the home's total land area and supporting a rich variety of creatures in its nearly inapproachable innards, is also able of supporting a small mortal population despite its scarce fresh water, but access is delicate, owing to its external props being steep limestone escarpments covered by sharp coral.

Explain what water pollution is and state the human activities that causes water pollution.
The presence of harmful chemicals and biological agents in groundwater that go above and beyond what is normally present in the water and may be hazardous to the environment and/or human health is referred to as water pollution. Additionally, substances that have been added to water bodies as a result of numerous human activities might constitute water contamination. Regardless of the risk they may represent to the environment and human health, any quantity of harmful substances pollutes the water. Water pollution is a hideous problem all around the world that is caused entirely by human behavior. So, what would it take to stop or in the very least reduce the rate of significant water pollution? The answer includes creating and imposing laws on how waste is disposed on a large scale, such as factories and farms, as well as educating the overall public on what each person can do to contribute to the solution instead of the problem. The major causes of water pollution in today’s society are from household sewage, industrial manufacturing, and agricultural runoff. Laws such as Clean Water Act of 1972 have been helpful but now, half a century later it is in need of an overhaul to address the polluting sources not included in the original version. Examples of which include indirect source polluting from farm and residential runoffs that carry with them pesticides, household chemicals, and even pharmaceuticals right to the steams and oceans infesting marine life and drinking waters. The ultimate solution is to come at the problem from both ends, cleanup the waste that is already in the water systems throughout the globe, but more importantly stopping or at the very least significantly cutting down on the careless polluting practices currently in place. That is why it is vital to publicize this problem, educate on the causes and effects of society’s activities, and fight for creation and enforcement of stricter laws for waste disposals.
If global climate change results in an area of temperate grassland receiving less rainfall and higher temperatures, it will ________.
If global climate change causes a temperate grassland region to get less rainfall and higher temperatures, it will start to support more desert species.
Global climate change refers to long-term average changes over the whole planet. These include rising temperatures and precipitation changes, as well as the repercussions of global warming, such as: Sea levels are rising. Mountain glaciers are receding.
Climate change will most certainly impact the makeup of grassland communities, but complex interactions make forecasts difficult.
Extreme weather events can cause a swift and severe reaction, affecting both ecosystems and human groups . Droughts, floods, fires, and hurricanes are anticipated to have a greater impact on grassland ecosystems in the United States. Drought worsens soil erosion and depletes aquifers. Increased precipitation variability favors more frequent fires, that can minimize the encroachment of woody plants into grasslands.

Compared to continental air masses with the same air temperature, maritime air masses: have lower water vapor content. have about the same water vapor content. have higher water vapor content.
Maritime air masses have higher vapor content compared to continental air masses with the identical air temperature.
First of all, we want to grasp what's air mass?
An Air mass said to an outsized volume of air during which the atmosphere that's mostly uniform in temperature and moisture in nature. It can extend thousands of kilometers across the surface of the planet, and can also reach from ground level to the stratosphere upto16 kilometers i.e., (10 miles) into the atmosphere.
Meteorologists have their own method of identifying air masses in keeping with which they form over the planet. There categorized atmospheric state in four; arctic, tropical, polar and equatorial. Arctic air masses are formed in Arctic region and known to be very cold. Tropical air masses form in low-latitude areas which are moderately warm. Polar air masses forms in high-latitude regions and are cold. Equatorial air masses shapes near the Equator, and are warm.
Air masses were also identified supported whether or not they form over land or over water. Maritime air masses form over water and are humid on the opposite, Continental air masses form over land and are dry.
It can clear with an example of atmospheric states that develops over northern Canada which is termed a continental polar atmosphere is claimed examine to be cold and dry and one that forms over the Indian Ocean is thought as maritime tropical air mass which is warm and humid.
With the above explanation we conclude our answer which is Maritime air masses have higher vapor content compared to continental air masses with the identical air temperature.
