Given parameters;
The radius of a circle is increased by a factor of x;
let the radius of the circle = r;
The increased radius = rx
Area of a circle is given as πr²;
Initially, the area of the circle = πr²
where r is the radius
New area after the increase = π x (rx)² = πr²x²
To compare the factor with which the area increased;
Factor = [tex]\frac{New area}{original area}[/tex] = πr²x² / πr² = x²
The area increased by a factor of x²
How does the availability of resources impact whether a tribe is sedentary or nomadic?
Hey there! I'm happy to help!
Sedentary means you stay in one place and aren't very active. Nomadic means that you travel around a lot.
If there are a lot of available resources, the tribe will want to stay because having resources nearby will help them survive much easier. This would make them sedentary.
If there are scarce resources nearby, they will go away and look for more abundant resources, making them more nomadic.
Have a wonderful day! :D

Which explains the difference between the equator and the prime meridian?
The equator separates the Northern and Southern hemispheres, while the prime meridian divides the Western and Eastern hemispheres.
The equator separates the Western and Eastern hemispheres, while the prime meridian divides the Northern and Southern hemispheres.
The equator separates the Northern and Western hemispheres, while the prime meridian divides the Southern and Eastern hemispheres.
The equator separates the Western and Southern hemispheres, while the prime meridian divides the Northern and Eastern hemispheres.
Answer:
The equator separates the Northern and Southern hemispheres, while the prime meridian divides the Western and Eastern hemispheres.
Explanation:
The line that circles the Earth midway between the North and South poles is known as the Equator, whereas the Prime Meridian is the line that passes through Greenwich, England. The fictitious line that circles the globe's center is known as the Equator.
Thus, Option A is correct.
How are the Equator and the prime meridian similar?The Earth is completely encircled by the equator and prime meridian circles. The Northern and Southern Hemispheres are divided by the Equator.
At 0° latitude, the Equator is located. The Prime Meridian divides the hemispheres into the Eastern and Western. The Equator's line of zero degrees latitude separates the Earth into its two equal hemispheres (north and south).
Latitude of 0 degrees marks the location of the Equator. Caitlin Dempsey, map The Prime Meridian is a hypothetical line at latitude 0 degrees.

What happens due to divergent plate movement?
A. Mountain formation
B. Volcano eruption
C. Seafloor spreading
D. Earthquakes
Spreading of the seafloor occurs along divergent plate boundaries. When tectonic plates progressively migrate apart from one another, heat produced by the mantle's convection currents causes the crust to become more flexible and thinner. Thus, option C is correct.
What is the seafloor spreading due to divergent plate?As oceanic plates diverge, tensional stress causes fractures in the lithosphere. Although there is often extensive magma activity at spreading ridges, the driving factor for seafloor spreading ridges is tectonic plate slab pull at subduction zones.
Less dense material tends to ascend, often forming mountains or elevated seafloor regions. Eventually, the crust breaks.
Oceanic crust has a propensity to subduct, or dive under, neighboring continental plates or younger segments of oceanic crust because it cools and eventually becomes denser than the asthenosphere beneath.
Therefore, Seafloor spreading happens due to divergent plate movement.
