Answer is D: the current make up of the crust
Changes in the temperature of the Earth's core will do the following:
1. Cause the outer core to solidify
-this means that the liquid outer core which is responsible for generating the magnetic field protecting us humans from solar radiation will be gone
2. Cause the mantle to solidify
-this means that if the mantle solidifies, the plate tectonics will stop moving around, and if this happens, the earthquakes and volcanoes will not be produced anymore and also mountain ranges will not be renewed, and the earth will be flattened by erosion.
Sam is studying the interaction between porcupines, pinion pine trees, and pine bark beetles. Over the course of his study in Colorado, he observes the behaviors of 25 porcupines, records the location of 151 pinion pines, and traps 332 beetles.
His study include 3 populations
- Population ecology is the study of the factors influencing the number and distribution of animal and plant populations.
- The study of the development, control, and interactions of animal populations is known as animal population ecology.
- A population's growth may be significantly influenced by the behavior of its constituent individuals, and the presence of predators, prey, and competitors in the community will also have significant effects.
- The population is a level of organization that lies between individuals and communities, but there is no clear distinction between the phenomena that affect these levels and those of the population.
- Here Sam studies 25 porcupines, records the location of 151 pinion pines, and traps 332 beetles. hence 3 populations are being studied here.

o describe the characteristics of currency with the statements provided, the answers are...
- Currencies can vary from nation to nation.
Think of the style of currency within the United States, we have dollar bills, quarters, nickels, dimes, pennies, etc. In other countries such as Germany for example, they use a type of currency known as "Euros".
- Currencies are divisible and have denominations.
These denominations within the United States include: Pennies (1 cent), Nickels (5 cents), Dimes (10 cents), Quarters (25 cents), and the Native American Dollar Coin (1 dollar).
- The value of a nation’s currency can change, and this value is based on many factors.
In 1690, America used a paper currency system (These were called "paper notes") to fund "Military Expeditions" and later other colonies began to take up this system as well. Later in 1861 during the Civil War, the U.S began to issue non-interest-bearing Demand notes (Later earning the nickname "Greenbacks"). Throughout the years, these "Notes" went through many re-designs and eventually became the dollar we see today.
