Answer:
2.62 years
Explanation:
The half life of a material is the time taken for half of the number of radioactive atoms in a radioactive material to remain.
If a radioactive material is cut into pieces, each piece has the same half life as the whole material.
Hence, if Strontium-147 is cut into pieces, each piece will have a half life of 2.62 years, just as the whole material.

After the Mexican Revolution, the new government promised "land, bread, and justice for all." What does this slogan tell you about the living conditions of the people before the revolution?
This comes to show that the people were previously living an inhumane life. They most likely did not have access to safe grounds to settle on, did not have much access to foods such as bread, and most importantly, did not have a government that cared about delivering equality and care to its people.

Explanation:
Name the river that the Hebrews settled nearby in Canaan
Answer: Canaan, area variously defined in historical and biblical literature, but always centered on Palestine. Its original pre-Israelite inhabitants were called Canaanites. The names Canaan and Canaanite occur in cuneiform, Egyptian, and Phoenician writings from about the 15th century BCE as well as in the Old Testament. In these sources, “Canaan” refers sometimes to an area encompassing all of Palestine and Syria, sometimes only to the land west of the Jordan River, and sometimes just to a strip of coastal land from Acre (Akko) northward. The Israelites occupied and conquered Palestine, or Canaan, beginning in the late 2nd millennium BCE, or perhaps earlier; and the Bible justifies such occupation by identifying Canaan with the Promised Land, the land promised to the Israelites by God.

Studies have shown that there is a relationship between the type and location of boundaries and the distribution and depth of earthquakes along or near these boundaries. Many earthquakes, shown in the map as wide bands, occur along convergent areas. These areas experience varying depths of earthquakes. Where would oceanic-oceanic convergence most likely occur? Nazca plate converging with the South America plate, forming the Andes mountains Philippine plate converging with the Pacific plate, forming Mariana Islands in the Pacific Ocean Juan de Fuca converging with the North American plate, forming the Cascade mountains North America Plate converging with the Eurasian Plate, forming a mid-ocean ridge
Answer:
Philippine plate converging with the Pacific plate, forming Mariana Islands in the Pacific Ocean
Explanation:
Oceanic convergence is the process resulting from the impact generated by the collision of two oceanic plates. This impact causes the heavier plate to sink to the point of being below the less heavy plate. The stronger the impact, the lower the heavier ocean plate will descend and the further it descends, the more it will be heated by the earth's mantle. As this plate is heated, the materials that melt and are incorporated into the mantle that increases in volume to the point of creating cracks in the terrestrial surface. This is how volcanic islands are formed, as well as cracks, similar to trenches on the seabed, are also created. Most of these volcanic islands are located in the Pacific, in the most easterly region. A strong example of this type of phenomenon is the Mariana Islands in the Pacific Ocean.

B) Philippine plate converging with the Pacific plate, forming Mariana Islands in the Pacific Ocean

describe the importance of growing plants
Answer:
Many human needs are met by plants and trees.
Most human needs for food, clothing, energy and medicinal needs are all met by plants and fruits, meat plants. Animals also depend on the existence of plants, meat fruits, and plants. Oxygen supply, carbon uptake from the environment and rainwater uptake into the soil, soil stabilization and prevention of soil erosion (high winds and showers) are other benefits of trees and plants in the environment.
The green space and the floral aroma of plants brought peace, joy and happiness to human beings. One of the most important places covered with trees and green space is the best place for recreation and human leisure. Existence of green space and trees can make the environment happy in landscapes and increase human life. Foliage of trees and plants absorbs airborne dust and reduces air pollution.
Airborne lead is the result of the activity of industrial units and motor vehicles and is one of the toxic and dangerous substances for humans, which is absorbed through respiration and has adverse effects and consequences on human health, which are caused by dense trees.

Artesian well:
Water pressure:
Zone of saturation:
Porosity:
Answer:
An artesian aquifer is a confined aquifer containing groundwater under positive pressure. An artesian aquifer has trapped water, surrounded by layers of impermeable rock or clay which apply positive pressure to the water contained within the aquifer.
A force that makes a flow of water strong or weak high/low water pressure.
The soil or rock located below the top of the groundwater table. By definition, the zone of saturation is saturated with water. Also see water table. Where raw wastewater is exfiltrating from a sewer pipe, the area of soil that is moistened around the leak point is often called the zone of saturation.
Porosity or void fraction is a measure of the void spaces in a material, and is a fraction of the volume of voids over the total volume, between 0 and 1, or as a percentage between 0% and 100%. Strictly speaking, some tests measure the "accessible void", the total amount of void space accessible from the surface.

Why is the distance between two meridians at the North Pole 0 miles?
Answer:
They are meeting at the North Pole. the North Pole & South Pole are the only places where lines of longitude meet and the distance is 0 miles.
Explanation:
Unlike parallels, which are always parallel to each other, meridians converge as they approach the poles. This causes a degree of longitude to vary from approximately 69 statute miles at the Equator (a great circle) to 0 miles at the poles.
