a

Explanation:

The accurately describes one impact of the atmosphere on Earth's cycles is "Oxygen transfers carbon from plants to animals." Thus option (C) is correct.

Oxygen is a part of the atmosphere, and it plays a crucial role in the carbon cycle. During photosynthesis, plants use carbon dioxide from the atmosphere to produce glucose, which is then broken down during respiration, releasing carbon dioxide back into the atmosphere.

Therefore, oxygen enables the transfer of carbon from plants to animals and back to the atmosphere, making it an essential component of the carbon cycle.

What is a waterway?

On the surface of the Earth, there are various bodies present in which there is water that gets navigated through rivers, canals, or streams. These bodies are known as the waterway. In simple words, a way through which water reaches to the people for use is known as the waterway. These waterways also include lakes, reservoirs, and docks.

In these waterways, there are some barriers also which help to store the water for that period of time in which there is a scarcity of water availability and these barriers are locks, weirs, dams, and rapids. To build the barriers, it is necessary that these waterways should have a broad distinction. If the waterways have enough broad distinction, then it is easy for ships to move on these routes.

Thus, Option C is correct.

Which two states call their counties something else (boroughs and parishes) ? Question 3 options:
New York and Maine

Alaska and Louisianna

Answers

Answer:

Alaska and Louisiana.

Explanation:

Counties are a type of internal territorial subdivision in the United States, with a lower hierarchy than states. Thus, a set of several counties in turn forms a state. They are, in short, the form of local territorial organization of a specific and determined area, in turn made up of several cities.

The name "County" is used in the vast majority of the 50 states, except for two particular cases: Alaska and Louisiana. Thus, in Alaska these types of organizational structures are called "Boroughs", while in Louisiana their name is "Parishes", thanks to its French colonial heritage.

In geography, a pattern is understood as an organized arrangement of elements, this can include the arrangement of natural elements such as mountains but also the arrangement of human-made elements because these are related to spatial relationships. In the case of the example described, the geographer is studying a pattern because the focus is to understand the arrangement of restaurants in the city. Also, this topic is related to how humans understand and use space.

Our current best estimate is that the western Grand Canyon in Arizona began to be excavated by riser erosion about 6 million years ago. The greatest depth of the Grand Canyon is about 1 .6 km. Required:a. Is the mean (average) rate that the Grand Canyon has been eroded into the Color-ado Plateau during the past 6 million years. expressed in millimeters per year? Show your work below. b. If erosion of the Grand Canyon proceeded at that rate during the most recent century, how much deeper is it today than it was on the day you were born? Show your work.

Answers

Answer:

0.267mm/yr

7.25 mm

Explanation:

Given the following:

Estimated time since erosion began = 6 million years

Greatest depth of canyon = about 1.6km

The mean rate of erosion in millimeter per year:

Mean rate = Depth of canyon / time

Depth of canyon in millimeter:

1 km = 1000000 mm

1.6km = (1.6 × 1000000) = 1,600,000 mm

Mean rate = 1,600,000mm/ 6,000,000 years

Mean rate = 0.26666 mm/yr

Mean rate = 0.267 mm/year

B.) If rate of erosion = 0.267mm/yr

Date of birth = 30 / 10 / 1992

Today's date = 5 / 9 / 2020

Date difference = 27 years 55 days

Total number of days = (27 *365) + 55 = 9,910 days

Rate of erosion per day = 0.267 / 365 = 0.0007315 mm / day

Change in depth from date of birth till today:

0.0007315 mm/day × 9,910 days

= 7.2492328 mm

= 7.25 mm deeper

A. If  the mean (average) rate of the Grand Canyon has been eroded into the Color-ado Plateau during the past 6 million years, the it being expressed in millimeter would be:

Estimated time since erosion began = 6 million years

Greatest depth of canyon = 1.6km

Average

Average is a number expressing the central value in a set of data which is the mode, median or mean which is calculated by dividing the sum of values in their set by their numbers.

Therefore, the mean rate of erosion in millimeter per year:

Mean rate = Depth of canyon / time

Depth of canyon in millimeter:

1 km = 1000000 mm

1.6km = (1.6 × 1000000) = 1,600,000 mm

Mean rate = 1,600,000mm/ 6,000,000 years

Mean rate = 0.26666 mm/year

Mean rate approximately = 0.267 mm/year

B. If erosion of the Grand Canyon proceeded at that rate during the most recent century, the depth of it today than it was the day i was born would be:

If  the rate of erosion = 0.267mm/year

Date difference = 27 years 55 days

Total number of days = (27 *365) + 55 = 9,910 days

Rate of erosion per day = 0.267 / 365 = 0.0007315 mm / day

Therefore, the Change in depth from date of birth till today: 0.0007315 mm/day × 9,910 days = 7.2492328 mm

Approximately = 7.25 mm deeper

The correct answer is D. How national borders in a region change over time.

Explanation:

The main purpose of maps is to show geographical features including natural physical features such as mountains or rivers, and political features that refer to the use of land by humans and the divisions created by them. Due to this, through maps, it is possible to visually show cities, states, regions countries, etc. In this context, a series of maps can be used to show the evolution or change of national borders because this is part of political features.
