Why do archaeologists carry out an excavation?

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.

Archaeological excavation is the procedure by which archaeologists define, retrieve, and record cultural and biological remains found in the ground. Past activities leave traces in the form of house foundations, graves, artifacts, bones, seeds, and numerous other traces indicative of human experience.

One may also ask, what do we learn from excavation? Excavation techniques have developed over the years from a treasure hunting process to one which seeks to fully understand the sequence of human activity on a given site and that site’s relationship with other sites and with the landscape in which it is set.

Furthermore, what did archaeologist find during excavation?

These data include artifacts (objects made or modified by humans), features (modifications to the site itself such as post molds, burials, and hearths), ecofacts (evidence for the local environment and resources being used such as snail shells, seeds, and butchered bones) and, most importantly, archaeological context (

Why is archaeological excavation destructive?

Archaeological excavation is often destructive as it is the study of cultural layers and to reach a layer under another, the layer above is removed. This is why: modern archaeology tries to study just a section of a site, leaving the remainder for the future (imagine taking a slice from a pie);

What are archaeological methods?

The archaeological method helps scientists uncover artifacts responsibly. When archaeologists begin the excavation, they don’t just start plowing shovels into the ground. First they create a grid system to help record where objects are unearthed. Then they gently start moving the earth one tiny trowel full at a time.

What are the two types of excavation?

What are the hazards of excavation?

The hazards and risks are usually: People and vehicles falling into the excavation. The undermining of nearby structures causing their collapse into the excavation. Damage to underground services during excavation work causing electrocution, explosion, gas escape, flooding etc. Ingress of water causing flooding.

Who studies the time before human writing?

Scholars define prehistory as events that occurred before the existence of written records in a given culture or society. History refers to the time period after the invention of written records in a given culture or society.

What is the difference between horizontal and vertical excavation?

In vertical excavation, the archeologist may use test units to identify and/or remove strata. In horizontal excavation, the archeologist may plow strips along the surface of the site to expose any objects lying near the surface.

Why are excavation sites divided into grids?

Answer and Explanation: Excavation sites are divided into grids so that archaeologists can record the exact location where artifacts are found.

How do you make excavations safe?

10 Excavation Safety Tips Inspect trenches daily before work begins. Check weather conditions before work, be mindful of rain and storms. Keep heavy equipment away from trench edges. Be mindful of the location of utilities underground. Always wear proper protective equipment. Don’t work beneath raised loads.

What is Isarchaeology?

Archaeology is the study of the ancient and recent human past through material remains. Archaeology analyzes the physical remains of the past in pursuit of a broad and comprehensive understanding of human culture.

How do you excavate?

Part 2 Excavating the Trench Remove the topsoil. Begin the digging. Dig your first cut to the appropriate depth. Keep the removed soil as far from the excavation as possible. Move along the length of your trench as each section is excavated to the required depth. Check the completed trench. Complete the project.

Why is Archaeology important today?

The goal of archaeology is to understand how and why human behavior has changed over time. Archaeologists search for patterns in the evolution of significant cultural events such as the development of farming, the emergence of cities, or the collapse of major civilizations for clues of why these events occurred.
