Answer:
It was the result of a colossal impact onto the accumulating Earth flinging raw materials, forming the moon.
It took approximately one million years for the moon to form the Lunar Highlands. 3.9 billion years ago, a vast amount of asteroids and meteorites impacted the moon and reformed the it’s surface. Many people came to believe that at one time the moon’s surface was actually smooth, but when this bombardment of meteorites and asteroids occurred craters were formed. The lunar highlands are light in color, mountainous, and heavily covered with craters. The highlands contain the oldest rocks on the moon which are known as anorthosites, they are composed almost entirely of plagioclase feldspar with a calcium end group ( CaAl2Si2O8). Anorthosites seemed to have formed when feldspar crystallized and floated to the top of a global magma ocean that surrounded the Earth soon after it formed. So the highlands were most likely formed by the magma ocean.
The Maria, which contain many of the Moon’s largest craters called the basins, were most likely caused by the lunar cataclysm. The mare rocks are young compared to the highland rocks, being formed at approximately 3.3-3.6 billion years ago. They contain mostly basaltic rock- a rock with a high percentage of iron ( 17%-22% by weight) and a wide range of titanium (1%-
13% by weight) and a relatively low albedo as compared to the anorthositic highlands.
Rilles can come to be several kilometers wide and hundreds of kilometers in length. They are said to be formed from lava flowing above or under Earth’s surface, and are better known as “lava tubes”.
3 Types exist:
Sinuous Rilles- meander in a
curved path
Arcuate Rilles- have a smooth
curve and are found on the edge
of the lunar mare
Straight Rilles- follow a linear
path and are believed to be
grabbens- areas where the crust
has sunk between two parallel
faults.

2.Environmental threat #2

3.Environmental threat #3
(reason they are losing habitat, food, etc.)
Explanation:
The key findings from many years of study of tiger population have indicated that in many sites, tigers decline in numbers because of habitat loss and prey depletion rather than being killed directly. A tiger needs to eat about 50 deer-sized animals or 6,600 pounds of living prey every year. Wherever prey-base is adequate and good protection measures are in place tiger populations reach high numbers simply because the species breeds quickly.
Prey species itself depend on conditions of the habitat. 21 tiger reserves in India out of 28 had lost about 250 square km of forest from 1997 to 2002. In the outer surround (within 10km from periphery of a tiger reserve) forest cover declined over the same period by 124 sq km in the same reserves. Tigers typically survive in what scientists call meta-populations — a source population with breeding females living in dense patches of forests — surrounded by dispersing tigers making their way into not so well kept nearby forests. Now when both core and buffer zones are under pressure, the tiger is hardly likely to be unaffected.
The National Tiger Conservation Authority (NTCA) commissioned a study by Wildlife Institute of India (WII) to show how much of India’s forests in tiger habitats are really capable of supporting the cat. In Shivaliks, comprising Corbett National Park and other areas, only 20.34 per cent were found of capable of really holding the tigers. The rest is too degraded and under pressure from human activity. Similarly, in central India, only 38.5 per cent could support tigers.
According to RPS Katwal, additional director general, wildlife in the Union ministry of environment and forest, increasing human habitation in and around forest sanctuaries, immense shortage of manpower in forest department and lucrative smuggling trade in wildlife to China and South East Asian nations are proving to be major stumbling blocks in the protection of the big cat in India. To kill tigers rich smugglers employ poor gullible villagers and they do it for a few thousand rupees

Which of the following is not a function of a vertebrate’s endoskeleton?
a.) Increase speed of digestion
b.) Protect major organs
c.) Offer support and structure
d.) Connect with muscles to create movement
Increase speed of digestion is not a function of a vertebrate’s endoskeleton. So, the correct option is (A).
What is Endoskeleton?
The rigid part which provides internal support of the structure is called endoskeleton which develops from endoderm and is called a living structure. Some examples of endoskeleton are cartilage, bone etc. The hard part that is on the outside of the body that protects the soft tissues and muscles is called the exoskeleton.
Vertebrates are animals that have a backbone and an endoskeleton which is a skeleton inside their body while invertebrates are animals that do not have a backbone. Invertebrates may have a skeleton on the outside of their body called an exoskeleton, while some invertebrates have no skeleton at all.
It protects major organs, offer support to the structure, connect the muscles to create movement.
Thus, Increase speed of digestion is not a function of a vertebrate’s endoskeleton. So, the correct option is (A).

Explanation:
Environmental impact has also been seen through human activity with agriculture. This is due to the high amounts of monoculture farming. Although having large agricultural fields of one crop can be efficient, it results in attracting a higher number of pests, which, in turn, results in a high use of pesticides. Identify a solution that would possibly remedy this issue and explain why that action would be beneficial.
Explanation:
Pesticides, fertilizers and other toxic farm chemicals can poison fresh water, marine ecosystems, air and soil. They also can remain in the environment for generations. Many pesticides are suspected of disrupting the hormonal systems of people and wildlife. Fertilizer run-off impacts waterways and coral reefs.

jill made the table below during her research on aquatic zones and living organisms. Based on jills observations, which conclusion can you draw? (ik the answer i just need the explanation)
Answer:
B. There are no producers in the benthic zone that relay on photosynthesis.
Explanation:
There are no producers present in the benthic zone because benthic zone is located in higher depth where there is no sunlight so no photosynthesis occurs there. We know that photosynthesis only occurs in the presence of sunlight, if there is no sunlight then there is no photosynthesis occurs and as a result no producer can survive there so we can conclude that there is no producers present in the benthic zone .

what're the two body systems opossums use to fake their death?
Apparent death, colloquially known as playing dead, feigning death, or playing possum, is a behavior in which animals take on the appearance of being dead. This form of animal deception is an adaptive behavior also known as tonic immobility or thanatosis. Apparent death can be used as a defense mechanism or as a form of aggressive mimicry, and occurs in a wide range of animals.
When induced by humans, the state is sometimes colloquially known as animal hypnosis. According to Gilman et al.,[1] the investigation of "animal hypnosis" dates back to the year 1646 in a report by Athanasius Kircher.
Opossums do not virtually play lifeless whilst they are threatened. Instead, they involuntarily input a catatonic kingdom.
Opossums, as they're generally called, are much more likely to run the alternative way, uncover their tooth, and growl in risky situations.
Playing dead is an involuntary reaction at the a part of the opossum. The strain of the war of words going through the opossum reasons him to enter surprise. This surprise induces a comatose kingdom that may remain for forty minutes.
Why ringtail Opossums don't play dead.No, ringtail Opossums they do not, they make a sound, you could concentrate on it on the subsequent post: Strange Australian Back Garden Beastie Sounds.
Therefore it is clear that they play dead by unover their tooth and growling in risky situations.
