Answer:
By excavating the kitchen area the archaeological team understands the ways of the ancient villages' consumption of food and the trading of the consumable items along with the potteries which can be found in the waste dump areas. By excavating these villages the pattern of growing crops can be understood if they cultivated or consumed wild crops, along with whether the society was agrarian or hunter-gathering. The dietary patterns of eating, drinking, and utensils with food residues can be examined.

hope this helped
Explanation:
a.) Dry unit weight b.) Void ratio c.) Porosity d.) Degree of saturation Solution: a) γd= γ1+?= 17.611.108= 15.89 kN/m3b) γd= γ? ?1+15.89 = (2.67)(9.81)1+e = 0.65 c) n = e1+= 0.651.65= 0.39 d) Se = wGsS = (0.108)(2.67)0.65x 100% = 44.50% 3.2Refer to Problem 3.1. Determine the weight of water, in KN, to be added per cubic meter of soil for: a.) 80% DEGREE OF SATURATION b.) 100% DEGREE OF SATURATION Solution: a. ) S = v? ??∆S = 80 –44.50 = 35.5% n = v? ?; VT = 1m3 0.39 = v? 1Vv = 0.39 0.355 = v? 0.39; Vw = (0.355)(0.39) Vw = 0.140 m3 Ww = 0.140 x 9.81 = 1.37 Kn
Answer:
Population pyramid is used to show the changes taking place in demography of country.
Explanation:
- The population pyramid shows the demographic structure of a community. Births, deaths, and migration are three important components of population change that alter the trends in the population composition of a place.
- The main economic reason why the people under the age group of 50 are less likely to migrate to the community is due to they have good earnings and better standards of living.
- One social factor that can attract the migrants that are over the age of 65 is social linkages and cultural ties. The population of females that is vier 80 years of age is more in numbers due to they have better health conditions.
- The population pyramid can be used to show social welfare as it harnesses human capital over time.
Answer:
A, C, D
Explanation:
The Gulf Stream is a warm ocean current in the Atlantic that carries warm water from tropical latitudes towards the more northerly latitudes of Western Europe. The effect of this current on the climate of the western part of the European continent es enormous. Many European cities at the same latitudes as Canadian cities with sub-polar climates enjoy temperature cool climates thanks to the moderating effect of the Gulf Stream that reduces the continentality and high latitude effects of the location.
Answer:
Freeeze-thaw weathering
Explanation:
Freeze- thaw weathering involves the breakdown of rock particles into smaller fragments through continuous fluctuations in the temperature of the water bodies. This form of weathering is common along coastlines. The water enters the rocks and then freezes when there is a decrease in temperature. The freezing expands the rock particles and aids frictions between the rock parts. This helps in the breakdown of the rocks to smaller particles.
It involves temperatures fluctuating around 0°C and is the dominant mechanical weathering process on coastlines
