Hello! I have 2 questions here I'm struggling with,
1.
Explain how scientists use the law of superposition and index fossils to determine the relative age of an unknown item.

2.
Identify and describe the two main methods for measuring the age of Earth and its parts

Answers

Answer 1

Identify and describe the two main methods for measuring the age of Earth: Radiation Measurement.

Stratigraphic Superposition.

Explain how scientists use the law of superposition and index fossils to determine the relative age of an unknown item:

Scientists read the rock layers knowing that each layer is deposited on top of other layers. The law of superposition states that each rock layer is older than the one above it. So, the relative age of the rock or fossil in the rock or fossil in the rock is older if it is farther down in the rock layers.

Global refers to D. the whole planet.Let's take the example of the Co.vid-19 pandemic. We can call this a global pandemic because the whole planet is affected by it & not just 1 region or country. One nation's issues are referred to as national issues & since US is 1 nation, it applies here as well.A community's concerns are known as community problems.So, option D. the whole planet is the correct answer.

the container in figure 5.1 33 is made from a circular cylinder and a cube the height of the cylinder is 20 cm and its base radius is it that cube has sides of 16 cm
calculate the volume in cm3 of the cylinder and the total volume of the container on cm3 ​

Answers

Answer:

Volume of cylinder = 4019.2 cm³

Total volume of container = 8115.2 cm³

Explanation:

Given that :

Height of cylinder, h = 20 cm

Base Radius of cylinder, r = 8cm

Volume of a cylinder, V = πr²h

Volume = 3.14 * 8² * 20

Volume = 3.14 * 64 * 20

V = 4019.2 cm³

The volume of a cube, V = a³ ; where a = edge of the cube

Edge of the cube, a = 16 cm

Hence,

V = a³ = 16³ = 16 * 16 * 16 = 4096 cm³

The total volume of the container is :

Volume of cube + Volume of Cylinder

4019.2 cm³ + 4096 cm³

= 8115.2 cm³

What was the rate at which the glacier's toe retreated (through melting/sublimation) between 1818 and 1882

Answers

Answer:

Explanation:

The missing part of the question is shown in the diagram attached below:

From the image attached, we can see the Map of Rhone Valley glacier in Swiss Alps.

To determine the rate at which the glacier's toe retreated between 1818 & 1882;

Let start by determining the scale of the map

Using the scale of  1.5cm = 3000 feet

Then;

1 cm = 2000 feet

So, if the ice retreated 2.1cm;

Then to feet, we have:

2.1 cm * 2000 feet = 4200 feet

Hence, the required rate at which the glacier toe retreated is:

[tex]= \dfrac{4200}{1882 -1818} \\ \\ =\dfrac{4200}{64}[/tex]

= 65.63 feet/year

How widespread was sharecropping in the South in the late 1800s?
All the Southern states had sharecropping on more than half their farms.
All the Southern states had sharecropping on less than half their farms.
Sharecropping varied from state to state, but it was common in many places.
Sharecropping varied from state to state, but it was never very common.

Answers

Answer: Sharecropping varied from state to state, but it was common in many places.

Explanation:

With the Civil War having ended slavery, Southern states still needed cheap labor to work on their farms and so they turned to sharecropping. As most of the South was plantation based, sharecropping took hold in many places.

Sharecropping however varied from state to state based on local laws and norms. In some areas, the sharecroppers were more at a disadvantage due to the laws passed by the state and this led to a lot of them living in abject poverty.

Answer:

C. Sharecropping varied from state to state, but it was common in many places.
