How long do scientists estimate that the sea has been at its current level?

8 0

A 2014 Reuters analysis found that, before 1971, water reached flood levels no more than five days every year (on average) in several U.S. east coast cities. Since 2001, however, that number has risen to 20 days or more (on average).

Answer:

B. 2,500 years

Explanation:

As the current sea level has risen about 130 meters which is higher than histrionic mean sea levels. Where the last glaciation took place about 20,000 years ago. And last time the sea levels where higher was during the eemian period.

What have scientists used to build a chronology of earths past

eduard

Hi,

Scientists have used rock samples to date the Earth's past. They also might use Steno's principles.

Relative dating is the determination of the age of a rock or geological event by comparing with other rock/ geologic events. Absolute dating is a form of geologic dating that gives an actual date or age in history that the item was formed or died in years.

Steno's principles are:

Law of superposition - Bottom layer is the oldest, top layer of the youngest In undisturbed layers of sedimentary rock or magma.

Original horizontally - When sedimentary rock layers form, they are "created in a horizontal form.

The Principle of Lateral Continuity - States that layers of sediment initially extend laterally in all directions.

Located at the leading edge of a temperature drop off. Bring heavy thunderstorms, rain, and hail. Cool, fair weather is likely

kolezko [41]

The answer would be B) Cold Front. A cold front would bring heavy thunderstorms, rain, and hail. A cold front would be located at the leading edge of a temperature drop off as well as be followed by cool, fair weather.

On a coordinate plane, a line goes through (negative 3, negative 3) and (negative 1, 5). What is the equation of the line parall

DENIUS [597]

Answer:

y=4x-16

Explanation:

The general form of the equation of a line is: y=mx+x, where m is the gradient and c is the y-intercept.

Given points (-3,-3) and (-1,5)

We are to find the equation of the line parallel to the given line with an x-intercept of 4.

First, we determine the value of the gradient of the line.

Gradient,

$m=\frac{y_2-y_1}{x_2-x_1} \\=\frac{5-(-3)}{-1-(-3)} \\=\frac{5+3}{-1+3}\\=\frac{8}{2}\\m=4$

Two lines are parallel if their gradients $m_1 \: and \: m_2$ are equal.

The gradient of the line parallel to the given line $m_2=4$

Since the x-intercept of the new line is 4, a point on the new line, $(x_1,y_1)=(4,0)$

Substituting $(x_1,y_1)=(4,0)$ into the equation of a line: , $y-y_1=m(x-x_1),$ we have:

$y-0=4(x-4)\\$Therefore:\\y=4x-16$

Therefore, the equation of the line is: y=4x-16
