B) Ontario
C) Nova Scotia
D) Ellesmere Island
The answer is: D. ellesmere Island
a location would be considered to has a arctic climate If the area continously undergone long cold winter followed by short cool summer, and the cycle would repeat.
Ellesmere Island has these criterias. But since the condition in this area is very harsh, there was very little people actually stay in this area.
I believet the answer would be D. Ellesmere Island

A carbon-14 sample starts with 100 atoms, and 5,730 years later, there are 50 atoms the half-life of carbon-14 are 5,730 years
The chemical element carbon has the atomic number six and the letter C assigned to it. It has a tetravalent atom, which means that four of its electrons can be used to create covalent chemical bonds. It is nonmetallic. The periodic table's group 14 includes it. The crust of the Earth contains 0.025 percent carbon.
Similar to hydrogen, oxygen, lead, and all the other chemical elements listed in the periodic table, carbon is an element. An extremely common element is carbon. As in diamonds and graphite, it can exist in pure or almost pure forms, but it can also interact with other elements to form molecules.
The half-life of carbon-14's degradation into nitrogen-14 is 5730 years, making it an unstable element. The time it takes for half of the Carbon-14 atoms to decay back into Nitrogen-14 is therefore 5730 years.
Therefore, Thus option (c) is correct.

Answer: C
Explanation:
Answer:
When acidic water soaks into the ground, water dissolves limestone, resulting in the formation of caves.
Explanation:
Groundwater causes erosion through hydraulic action and solution, leading to the formation of unique landforms.
Groundwater can cause erosion and deposition through two main processes: hydraulic action and solution.
ydraulic action occurs when the force of moving groundwater dislodges and carries away the particles of soil and rock. This can create channels and cavities, causing erosion.
Solution happens when groundwater dissolves certain minerals and rocks, such as limestone, leaving behind deposits.
For example, when groundwater flows through a limestone cave, it can dissolve the rock, leading to the formation of stalactites and stalagmites.
These are formed through the deposition of dissolved minerals from the water.
In summary, groundwater can erode and deposit material through hydraulic action and solution, shaping the landscape and creating unique landforms.

B. a culture in which both children and adults learn from their peers
C. a culture in which adults also learn from their children
D. a culture in which adults learn from their peers and their children
The movement of rivers. The water pressure of rivers can cut deep into a river bed. Rocks and things from the river bed are carried downstream, creating a narrow channel.
Please respond to the following prompt. Make sure that you compose a well-written paragraph that is all from your brain only! You can write it by hand or type it.
Why is it important for scientists to gather information before they begin to work on a problem?
Answer:
To correctly answer it.
Explanation:
Scientists need to gather information on a problem before solving it because it they don't gather the required information then they will end up with incorrect solutions for the problem.
