Final answer:
We live in the Phanerozoic eon, within the Cenozoic era, and are currently in the Quaternary period of geologic time.
Explanation:
Current scientific understanding classifies the divisions of geologic time first into eons, then eras, periods, epochs, and ages. The eon we currently live in is the Phanerozoic, which is known for abundant animal and plant life. Within the Phanerozoic eon, we are in the Cenozoic era, often referred to as the era of "modern life" or the age of mammals, which started approximately 65 million years ago.
The Cenozoic era is themselves divided into periods, and the period we live in today is the Quaternary. The Quaternary period is the most recent and encompasses the last 2.588 million years to the present. As part of the Quaternary period, we are in the Holocene epoch, which began around 11,700 years ago after the last major ice age.

Some cartoons have shown early humans keeping dinosaurs as pets. From what you know about Earth’s history, is this possible? Why or why not?
Before humans arrived on Earth, over 65 million years had elapsed since the extinction of the dinosaurs. However, there were tiny mammals present during the period of the dinosaurs, including primates the size of shrews.
What is the dinosaur's history on earth?The majority of the Mesozoic era, a geological period that spanned from 252 million to 66 million years ago, saw the existence of dinosaurs. The Triassic, Jurassic, and Cretaceous epochs are all part of the Mesozoic era. During the Triassic epoch, when the environment was severe and arid, dinosaurs evolved from tiny dinosauromorph forebears. For tens of millions of years, they had to compete with the croc-line archosaurs, but they eventually won when Pangaea started to separate, according to Brusatte.
Global warming and a catastrophic extinction occurred during this period as a result of volcanoes erupting along the supercontinent's fractures, he claimed. The Cretaceous period is when the biggest dinosaurs yet discovered lived, notably Argentinosaurus. The Cretaceous-Tertiary (K-Pg) extinction event, which occurred when an asteroid 6 miles wide hit Earth, marked the end of the Cretaceous era.

In the United States, the president, a civilian, is commander-in-chief of the armed forces. This means that the president is __________.
Correct answer: The president is not a member of the military.
Explanation:
A "civilian" means someone who is not a member of the military. Some presidents have formerly served in the military, but as elected officials in the White House, they are serving as civilians in that office.
A prominent stand-off over the President's authority over the military occurred during the presidency of Dwight Eisenhower. Eisenhower had been a military general himself (during World War II), but then was elected to serve as civilian commander in chief as President of the United States. In 1950, when North Korean forces invaded South Korea,General Douglas MacArthur wanted to bomb the People's Republic of China and use Nationalist Chinese forces from Taiwan also in an attack on communist China. President Eisenhower would not grant these requests to escalate the war, and MacArthur made his opposition to Truman's policies a public argument. Eisenhower felt he had to relieve MacArthur of his command and maintain respect for civilian control of the military, with the President as Commander-in-Chief.
Which of the following is a characteristic of a flintlock muzzleloader?
Final answer:
A flintlock muzzleloader is characterized by its flintlock mechanism for igniting gunpowder and its smoothbore barrel, as it loads gunpowder and projectiles from the muzzle, or front end, of the barrel.
Explanation:
A flintlock muzzleloader is a type of firearm that was used extensively in the 17th, 18th, and early 19th centuries. It is characterized by the flintlock mechanism, where a piece of flint held in the jaws strikes a steel surface to produce sparks, which then ignite the gunpowder to fire the projectile. Another notable feature is that it is a muzzleloader, meaning the projectile and gunpowder are loaded from the open end of the barrel at the front of the gun.
In contrast to flintlock muzzleloaders, rifled firearms such as the noted Enfield rifle have grooves (rifling) in the barrel that impart spin to the bullet, thereby increasing accuracy and range. Flintlock muzzleloaders, however, have smoothbore barrels and do not utilize this rifling pattern. The Enfield rifle's importance also stemmed from the American System of Manufacturing, which meant that parts were standardized and could be easily replaced, unlike earlier guns where each was handcrafted and unique.

Global warming is caused by an increase in the level of carbon dioxide gas in the atmosphere. How has this affected the world's oceans?
The effect on the worlds oceans are a large portion of the carbon dioxide gas is returned to the atmosphere by the oceans.
What is atmosphere?Atmosphere is defined as the layer of gases kept in place by Earth's gravity and forming its planetary atmosphere. In addition to preserving the oxygen we breathe, the atmosphere protects us from the Sun's harmful rays, maintains the planet's surface temperature, and is essential to the water cycle.
Global warming is defined as the phenomena of earth's average temperature gradually rising. Because more atmospheric carbon dioxide is dissolving in the water, the ocean has become more acidic during the past few decades. The mineral balance in the ocean water is impacted by higher acidity, which might make it more challenging for some marine species to develop their protective skeletons or shells.
Thus, the effect on the worlds oceans are a large portion of the carbon dioxide gas is returned to the atmosphere by the oceans.

Countries where a Kurdish revolt is likely to occur include _____.
Iran
Iraq
South Africa
Spain
Turkey
Iran, Iraq, and Turkey
Explanation:These regions have significant Kurdish populations who have historically sought independence and autonomy, aiming to establish a proposed country known as Kurdistan. The concept of an independent Kurdistan, comprising parts of these nations, has led to numerous insurrections that have often been met with violent suppression by the respective governments.
The Kurds are considered the largest ethnic group without a state, with significant populations in Turkey, Iran, Iraq, and a corner of Syria. In Turkey, where the largest Kurdish population resides, the city of Diyarbakir has been posited as the Kurdish capital of a potential Kurdistan. Despite historical attempts to gain statehood, including a petition at the 1945 UN conference, the Kurdish nation has yet to achieve an internationally recognized autonomous region. The inconsistencies in foreign support, particularly from the US, have also influenced the Kurdish struggle for independence.

A landslide is an example of which of the following:
A.
erosion agent
B.
mass wasting
C.
meandering
D.
evaporation
The right option is; B. mass wasting
A landslide is an example of mass wasting.
Mass wasting is the bulk movement of soil, sand, regolith, and rock downslope due to the force of gravity. A landslide is an example of mass wasting. Landslides occur in various environments that has steep or gentle slope gradients. Gravity is the major force that causes landslides, and it can also occur due to disturbance of slope, changes in groundwater, volcanic activity and earthquakes.
Mass wasting
Further Explanation:
The term landslide points out towards various other forms of mass wasting and that includes a wide range of ground movements. This phenomenon takes place almost at every part of the world. These forms of mass wasting include rock falls, mud flows as well as debris flows. Mass wasting takes place in variety of environments which is segregated by either steep or gentle steep gradients. The major force which is also known to be as the driving force behind these landslides is gravity but there are other reasons also involved behind mass wasting.
Many a times, mass wasting or landslides are triggered by a specific event which can be a heavy rainfall, earthquake or a slop cut in order to build roads etc. Landslides usually take place when there is a portion of the slope goes through some process which may stable it or unstable it. This phenomenon takes place due to decrease in the shear strength of the slope material and when that materials fails to hold on to that slope, landslide takes place.

deposition
abrasion
moraines
compression
Answer:
moraines
Explanation:
A striangulation means a grove that is created by a moving object such as a place on the surface of the rocks and this is either due to the fault moment and mostly occurs in areas of the glacial action. They can also occur n their habitats like that of the feldspar, quartz and the chalcocite.
