How have new technologies helped scientists determine the age of Earth?
Answer:
Radioisotopic dating as a new technology has really helped to determine the age of the earth.
Explanation:
The actual age of the earth has been a subject of wanton speculation among different groups of people. Speculations arise from religious, cultural and philosophical perspectives.
However, studies using many radioactive isotopes believed to be present from the origin of the Earth and having extremely long half lives have been most helpful in determining the age of the earth. Radioisotopic dating is a common technique used to determine the age of ancient artifacts. It has shed a great light on the possible age of the earth.
Hence the application of radioisotopic dating as a new technology has really helped to determine the age of the earth.

Answer:Despite seeming like a relatively stable place, the Earth's surface has changed dramatically over the past 4.6 billion years.
Explanation:Despite seeming like a relatively stable place, the Earth's surface has changed dramatically over the past 4.6 billion years. Mountains have been built and eroded, continents and oceans have moved great distances, and the Earth has fluctuated from being extremely cold and almost completely covered with ice to being very warm and ice-free. These changes typically occur so slowly that they are barely detectable over the span of a human life, yet even at this instant, the Earth's surface is moving and changing. As these changes have occurred, organisms have evolved, and remnants of some have been preserved as fossils.

⇒ https://brainly.com/question/15111409
The correct option to the answer is option C Reforestation
Reforestation is the method of replanting trees in places that have been damaged by both natural and manmade disturbances, such as lumbering, quarrying, agricultural production, and construction. Natural disturbances include wildfires, drought, pest and disease infestations, and wildfires. This could entail anything from encouraging revegetation in a degraded area to planting ecologically suitable tree seedlings in the wake of forest fires.
Reforestation improves the environment by ensuring or accelerating the restoration of healthy natural forests by sustaining and enhancing the forest canopy and preserving biodiversity within the ecosystem by planting trees in areas that have been deteriorated or eroded.
By storing carbon dioxide in the atmosphere in their leaves, and roots and absorbing toxic emissions into their bark and leaves, it aids in carbon storage.
Reforestation offers habitat for more than 80% of the planet's plant diversity and reduces soil erosion by establishing roots that hold the soil together. It functions as a natural air conditioner by lowering air pressure temperatures. By absorbing water and gradually releasing it through transpiration, plants can greatly aid in preventing floods and landslides.

The following best characterizes the asthenosphere as "a layer of soft, solid, magnesium silicates and molten iron droplets at the base of the mantle."(B)
The asthenosphere is a layer of the Earth's mantle situated directly under the lithosphere. The asthenosphere's thickness is about 180 km (112 miles) below the surface. It is composed of soft, weak material, similar to a weak plastic, made up of solid, magnesium silicates, and iron droplets that are molten.
The asthenosphere is believed to be partially melted, with partially molten rock flowing under higher pressure. These hot molten rocks transfer heat to the Earth's crust through convection currents. The movement of the material in the asthenosphere is responsible for the motion of tectonic plates and volcanic activity.(B)

calculate the longitude of the position of a ship whose navigation office obwerve that Greenwich mean time is 1416 hours when the local time is noon
Answer:
34 degree West
Explanation:
Given
Greenwich Mean Time (GMT) = 14:16 hours
Local Time = Noon = 12:00 hours
Required
Calculate The Longitude of the Ship's position
We start by calculating the time difference;
Time Difference= GMT - Local Time
Time Difference = 14:16 hours - 12:00 hours
Time Difference = 02:16 hours
Convert time difference to minutes
Time Difference = 02:16 hours
Time Difference = 02 hours + 16 minutes
Time Difference = 02 * 60 minutes + 16 minutes
Time Difference = 120 minutes + 16 minutes
Time Difference = 136 minutes
Convert Minutes to degrees
In GMT, 4 minutes it will rotate 1 degrees
So, 136 minutes = 136 degrees / 4
136 minutes = 34 degrees
Hence, the ship is 34 degree West

why we know much more about the ice-sheet margins at the lgm (and during the deglaciation) than we do about the pre-lgm ice sheets
The Last Glacial Maximum (LGM) occurred when ice sheets and glaciers throughout the world were at their maximum extent during the last ice age.
Furthermore, in some locations, the LGM was not the biggest glacier event of the LGC and some places saw smaller glaciers than earlier in the LGC.
What is The Last Glacial Maximum (LGM)?
The Last Glacial Maximum (LGM) was a major climatic event in the Last Glacial Cycle (LGC) and in many areas was a time of significant landscape change. Glaciers were often close to their maximum extent of the LGC over the 29- to 19-ka interval.
However, the evidence presented in this chapter reveals complexities in this extended interval with some areas seeing maximum glaciers at the beginning of this interval than others seeing maximum glaciers at the end of this interval.

How has Brazil's African heritage affected its culture today?
Answer:
Explanation:
A lot, specially in northeast and southwest.
I think that’s a lot complicated to say how exacly much is because most of african culture in Brazil was not just copy and paste but created here as well.
The Camdoble, for example, its “Brazilian” in the way that its a mix of different african religions, mixed again some Amerindians traditions and mixed again with catholicism. But not stop here, the catholicism itself is a lot mixed as well with theses African religions, no wonder a lot of people are Catholic AND Candomble, there’s a big relationship between Catholic Saints and Candomble “Orishas”.
It means that a lot of things which we may think that is “african” maybe is not, and a lot of things that not seems african may really is.
The most agnostic answer its say that is 33% African, 33% European, 33% Ameridian, 0,5% Middle East and 0,5% East Asian. Probably is not that, probably is more European (50%?) and less Ameridian, but its a good way to start.

It’s difficult for me to answer this A2A because I am originally from South of Brazil, where the African impact is almost non-existent. But here is what I can afirm for sure.
Brazil is not “an African nation” outside of Africa as many sugests. The reason behind it, is that africans were absorbed through centuries of racial mixing with Europeans and Native indians. So you may have to search a lot until you find a person that is 100% african in Brazil. But the African influence is huge in cultural terms.

What might cause some of the areas near 30 deg north and
south latitude to be dry deserts?
When Cold air and Warm air collide which is forced to
rise? Why?
The Hadley cell circulation is the reason for some areas near 30 degrees north and south latitudes to be dry deserts. In this circulation, dry air descends and warms as it sinks, causing high temperatures and low humidity.
The area near 30 degrees north and south latitude experiences dry conditions because the descending air absorbs moisture, which evaporates before it reaches the surface. Due to this, the regions experience minimal rainfall, which makes them arid or semi-arid. When warm air and cold air collide, the warm air is forced to rise above the cold air because of its lower density. The collision can create weather conditions such as thunderstorms, cumulonimbus clouds, and precipitation. The rising air cools as it rises to higher elevations, which can form clouds and, in some cases, rainfall. If there is not enough moisture to produce rain, the warm air can create warm fronts that can produce cloudy or overcast skies.
