Which of the following are units of air pressure? Select all that apply.
1.isobar
2.millibar
3.kilopascal
4.barometer
5.atmosphere
6.millimeter of mercury
Answer:
Options 2, 3, 5 and 6 are units of pressure.
Explanation:
You can use all to measure air pressure
Answer:
Options (2), (3) and (6)
Explanation:
Air pressure is usually defined as the weight that the atmosphere exerts downward on the earth's surface. This air pressure varies with the changes that occur in terms of height or altitude. The value of air pressure increases towards the mean sea level and decreases as the height increases.
This atmospheric pressure is commonly measured by an instrument which is known as a barometer. It helps in the weather forecasting.
The S.I unit of atmospheric pressure is Pascal (Pa). In the C.G.S system, the units used are millimeter (mm) of mercury and millibar (mb).
Thus, the correct answers are options (2), (3) and (6).
The area of a right triangle is 25 square meters. The height is twice as long as the base
The area of ANY triangle is
Area = (1/2) (base x height) .
If the height is twice as long as the base, then
25 m² = (1/2) (base) x (2 x base)
25 m² = base²
base = 5 m
height = 10 m
The base of the triangle is 5 meters and the height is 10 meters.
Explanation:To find the base and height of the right triangle, we can use the formula for the area of a triangle: A = 1/2 * base * height. Let's assume the base is x. According to the given information, the height is twice as long as the base, so the height is 2x. Plugging these values into the formula, we get 25 = 1/2 * x * 2x. Simplifying the equation, we have 25 = x^2.
Taking the square root of both sides, we get x = 5. So the base of the triangle is 5 meters. Since the height is twice as long, the height is 10 meters.
Therefore, the base of the right triangle is 5 meters and the height is 10 meters.

Which characteristics describe deep ocean currents? Check all that apply.
move slowly
caused by wind
move cold water
move in a circular pattern
caused by differences in density
Answer:
Options (1), (3), (4) and (5)
Explanation:
The deep ocean water refers to the water that is present at the bottom of the ocean. This deep water is highly dense, and are rich in essential nutrients including oxygen. Sunlight cannot penetrate into the deeper layer, as a result of which these water remains much colder and moves at a much slower rate in comparison to the surface waves. These deep ocean currents are generated by the density differences due to two factors namely, temperature and salinity.
These currents are moved from the equatorial region to the poles and again comes back from the poles to the equator, forming a circular pattern. This circulation of water is responsible for the various climatic conditions that occur at different places.
Thus, the correct answers are mentioned above.
Which statement best describes the theory of plate tectonics?
•plates sometimes move closer to one another
•sections of earth that shift are parts of earths asthenosphere
•sections of earths continents are in slow constant movement
•parts of the ocean floor move as they are carried by rift valleys
Answer:
The statement that best describes the theory of plate tectonics is the one that says that sections of Earth's continents are in slow constant movement.
Explanation:
Plate tectonics is a geological theory developed to explain the phenomenon of continental drift, that is, the continents of the earth are not invariably positioned on the surface of the earth but move in proportion to each other and constantly forming new combinations.
According to plate tectonic theory, the outermost part of the earth's interior consists of two layers, the outer lithosphere and the inner asthenosphere. Plate tectonics arose from two distinct geological observations: scattering zones and continental drift.
The theory of plate tectonics describes sections of earth's continents are in slow constant movement.
What is plate tectonics?Plate tectonics is the is present under the solid crust of the Earth that is known as lithosphere. These plates have the tendency to move in proportion constantly in order to form further new combinations.
Therefore, the theory is discussed as a scientific theory that demonstrates the formation of landforms due to the movements of Earth's subterranean.

x = 240,300 rounded to the nearest 100
Answer:
Distance in miles to the nearest hundred miles = 238900 miles
Explanation:
The average distance of the earth to the moon is 384, 400 km. To get the distance in miles we need to convert kilometer to miles .
1 km = 0.621371 miles
1 km = 0.621371 miles
384, 400 km = ?
cross multiply to get the miles value of 384,400 km
Distance in miles = 384,400 × 0.621371
Distance in miles = 238855.0124 miles
The nearest hundred miles is gotten when you locate the hundred value . The value start from the second 8 value upward . The closest hundred mile of 855 is 900 since 855 is more closer to 900 than 800.
Rounding to the nearest hundred miles = 238900 miles

1. a short stack of paper represented a region of Earth's surtace, which fold or cut
in the stack would show a monocline?
Answer:
A step-like fold across the stack -D
A monocline is a geological fold where one side of the fold erodes, leaving lifted layers on one side. This could be represented by a single fold in a stack of paper. Large-scale examples of folds are created by continental masses colliding, such as in the formation of the Alps.
Explanation:A monocline is a geological formation that results from an event where layers of rock have been folded due to immense pressure, but then one side of the fold erodes or wears away, leaving the uplifted layers on one side of the formation. If a stack of paper represents the Earth's surface, a monocline would be shown by a single fold in the stack, with the rest of the papers lying flat.
As an example, think about two continental masses moving towards each other. When these masses are colliding, they create immense pressure leading the Earth to buckle and fold. This folding forms various geological structures including monoclines. A good real-world example of this process is the formation of the Alps as a result of the African plate colliding with the Eurasian plate.

A. Fast-moving water from heavy rainfall forms deep channels. B. A raindrop hits the ground and displaces the surrounding soil. C. Runoff removes soil and loose sediment in thin layers. D. Runoff from heavy rainfall forms narrow, shallow channels.
Answer:
Runoff from heavy rainfall forms narrow, shallow channels. - D.
Rill erosion refers to the formation of narrow, shallow channels created by runoff from heavy rainfall, specifically when surface runoff concentrates in small channels, leading to soil particle detachment and transport.
Which of the following accurately describes rill erosion? The correct option is D. Runoff from heavy rainfall forms narrow, shallow channels. This type of erosion occurs when overland flow, or surface runoff, begins to concentrate in small channels on the soil surface, causing detachment and transport of soil particles.
These channels, known as rills, are typically less than 5 cm deep and can be erased with normal farming operations. Rill erosion commonly develops from sheet erosion, which is when raindrop splash and surface runoff remove a uniform layer of soil over a large area. As rills deepen and widen, they can eventually evolve into gullies, which are larger and cannot be smoothed out simply by tillage equipment.

Explanation:
ANSWER:
According to United States, globalization is intended to make the world a more interconnected and interdependent place.
EXPLANATION:
This interconnection includes increased trade and investment flows, exchange of culture, ideas, knowledge, currency exchange, rise of multinational corporations. In 1990s, the world has become more interconnected because the "communist bloc countries" that are isolated from the "capitalist West" began to integrate into the global market economy. Technological development like internet, using mobile phones have contributed to globalization across the globe. Free trade agreements such as "North American Free Trade Agreement" enabled the free flow of people, goods and services facilitating trade, investment and migration across borders of the country. One dark side is that the global terrorist networks have used the mobile technology to destroy the nations as migrations were easier compared to pre-globalization days.What's responsible for causing eutrophication in waterways?
