What is the role of Archaeology in the reconstruction of the past?

What is the role of Archaeology in the reconstruction of the past?

While archaeology can be a helpful tool in understanding past cultures and histories, it can also be used in a negative way to reconstruct narratives that justify certain unjust practices. Archaeology aids in constructing a skewed reality of the past by “othering” groups of people defend their discriminatory policies.

How does an archaeologist reconstruct history?

Answer: Archaeologists reconstruct the past by a study of the artefacts which they unearth such as seals, coins, remains of buildings, clay, pots or burnt grains. Archaeologists try to find about the prevalence of agriculture by finding the remains of burnt grains.

What ways do archaeologists reconstruct ancient environments?

Geoarchaeologists. They study a wide range of data, such as global climate, regional distribution of resources like stone for tools or clay for pots, local geomorphology or topography, and the clues that soil can provide in studies of ancient land-use.

Why is preservation important in Archaeology?

Archaeological discoveries let we as a species connect with our history: both our recent and our ancient past. Because of the emotional significance our species places on them, artifact preservation is a vital means of protecting these physical validations of our past. …

Why are excavations important?

Excavations can be classified, from the point of view of their purpose, as planned, rescue, or accidental. Most important excavations are the result of a prepared plan—that is to say, their purpose is to locate buried evidence about an archaeological site.

How are excavations done?

Some of the different processes used in excavation include trenching, digging, dredging and site development. Each of these processes requires unique techniques, tools and machinery to get the job done right. The processes used will depend upon the structure that will result from the construction process.

How do you select a site for excavation?

Ground-penetrating radar (GPR) and magnetometry are the two most common forms of such high-tech dig methods. Essentially, these devices narrow the search even more, after archaeologists have done their research and conducted preliminary surveys.

How is excavation helpful in learning history?

Archaeologists use special techniques and equipment to gather their evidence precisely and accurately. They must keep detailed records of their findings. This is an extremely vital activity. Once an excavation begins, it digs into — and digs past — many layers of structures.

Why do we need to learn about our past?

Studying history enables us to develop better understanding of the world in which we live. Building knowledge and understanding of historical events and trends, especially over the past century, enables us to develop a much greater appreciation for current events today.

What is the meaning of excavations?

1 : the action or process of excavating. 2 : a cavity formed by cutting, digging, or scooping. Other Words from excavation Example Sentences Learn More about excavation.

What are people who do excavations called?

When archaeologists or other people excavate a piece of land, they remove earth carefully from it and look for things such as pots, bones, or buildings which are buried there, in order to discover information about the past. To excavate means to dig a hole in the ground, for example in order to build there.

What does presumably mean?

assuming reasonably

How can we prevent excavation?

Provide protection by:

1. Set spoils and equipment at least 2 feet back from the excavation.
2. Use retaining devices, such as a trench box that will extend above the top of the trench to prevent equipment and spoils from falling back into the excavation.

What are the hazards in excavation?

1. Pit Excavation up to 3m

Type of hazard	Effects of hazard
Falling into pit	Personal injury
Earth collapse	Suffocation /breathlessness, Buried
Contact with buried electric cable, Gas / Oil Pipelines	Electrocution, and Explosion

What are some dangers of excavation?

Top 5 excavation safety hazards

• Cave-ins. Trench collapses kill an average of two workers every month, making this a serious threat to worker safety.
• Falls and falling loads. Workers and work equipment can fall into an excavated area.
• Hazardous atmospheres.
• Mobile equipment.
• Hitting utility lines.

What are the risk of excavation?

There are a range of health and safety risks associated with excavation work including:

• falls from one level to another.
• the fall or dislodgement of earth or rock.
• vibration and hazardous noise.
• exposure to an airborne contaminant .

What are the safety precautions in excavation work?

Excavation safety Precautions: Adapting soil protection method like stepping, sloping, shoring and close sheeting. If excavation reached more than 3 meter, shoring or close sheeting shall be done. Adequate barricade and excavation sign board. Gas test inside excavation before job.

Why excavation can cause landslide?

If the landslide is divided into the sliding and the anti-sliding sections, the more the anti-sliding section of the sliding body is excavated, the more the anti-sliding force will be reduced, resulting in a more unstable landslide. Therefore, unreasonable excavation will cause a landslide.

Why are trenches dangerous?

Life in the trenches was dangerous for many reasons. The more obvious dangers included enemy fire, poisonous gas attacks and artillery shelling. While the trenches offered general protection from enemy fire and artillery shelling, they could also be extremely dangerous places.

What was life like living in the trenches?

Trenches were long, narrow ditches dug into the ground where soldiers lived. They were very muddy, uncomfortable and the toilets overflowed. These conditions caused some soldiers to develop medical problems such as trench foot.

Do any of WWI trenches still exist?

There are a small number of places where sections of trench lines can still be visited. Nevertheless, there are still remains of trenches to be found in remote parts of the battlefields such as the woods of the Argonne, Verdun and the mountains of the Vosges.

What should you do if a cave in occurs?

Shielding involves using trench boxes also known as trench shields or other supports to protect workers inside a trench from collapsing soil if a cave-in occurs. The competent person should pick a trench box that is right for the soil type and all other site conditions.

What is the greatest danger associated with excavations?

• The greatest risk in an excavation is a cave-in.
• Employees can be protected through sloping, shielding, and shoring the excavation.
• A competent person is responsible to inspect the excavation.
• Other excavation hazards include water accumulation, oxygen deficiency, toxic fumes, falls, and mobile equipment.

What are some common causes of cave-ins?

Here are five factors that cause cave-in trench accidents:

• Inadequate Protection Systems in Place. A vertical wall of soil is generally unstable.
• Vibration.
• Stress Loading the Soil.
• Excavated Materials Located Too Close to the Trench.
• Failure to Inspect the Trench before Each Shift and after Weather Events.

What are some dangers of excavations quizlet?

The dangers of excavations come from the possibility of cave-ins, in addition to the possibility of the lack of oxygen (asphyxiation), fire, accidental break of underground utility lines (such as gas, electricity), collapse due to moving machinery near the edge of the excavations, inhalation of toxic materials, and …

Is fire a hazard associated with excavations?

If you are not using protective systems or equipment while working in trenches or excavations at your site, you are in danger of suffocating, inhaling toxic materials, fire, drowning, or being crushed by a cave-in.

How does OSHA define a competent person?

An OSHA “competent person” is defined as “one who is capable of identifying existing and predictable hazards in the surroundings or working conditions which are unsanitary, hazardous, or dangerous to employees, and who has authorization to take prompt corrective measures to eliminate them” [29 CFR 1926.32(f)].

Which of these is known as the greatest danger associated with excavations select the best option?
