Three strategies in which local municipality is implementing
in addressing the issue of lack of clean water are the following:
-
Having people to make campaigns or join
campaigns into having to save water
-
Having to implement a system of which factories
or companies to pay high taxes when they have resources or waste dump in the
water
-
Planting more trees and plants in which will
help in the environment and in the same way, it protects water and maintaining
balance.
Answer:
The Bulk density = 1.3 g/cm³
the porosity of the sample is 132 cm³
Explanation:
Given:
Volume of cylinder = 260 cm³
Mass of container and the soil = 403 g
Mass of the empty container = 65 g
Thus,
The mass of the soil is = 403 - 65 = 338 g
Now,
The Bulk density = 
or
The Bulk density = 
or
The Bulk density = 1.3 g/cm³
also,
average particle density for mineral soil is usually given as 2.65 g/cm³
i.e the air present in the given soil sample has reduced its density from 2.65 g/cm³ to 1.3 g/cm³
The mass of the whole sample = Volume × Density
= 260 × 2.65
= 689 gm
but,
The actual mass of the dry sample = 338 g
thus,
Mass of air in the sample = 689 - 338 = 351 g
Therefore,
the volume of 351 g soil = 
= 
= 132.45 cm³
so the porosity of the sample is 132 cm³
Answer:
No
Explanation:
Continental drift describes one of the earliest ways geologists thought continents moved over time. Today, the theory of continental drift has been replaced by the science of plate tectonics
The correct answer is - inner core.
The Earth's inner core is the deepest layer of the Earth, and it practically represents the center of the Earth. It is a layer composed predominantly of iron-nickel alloy. In here we have the biggest temperatures and pressures, the temperature on the surface on the inner core is estimated to be like that of the Sun's surface, 5430 C degrees.
