Answer:
Explanation:
As these fossils suggest, Antarctica hasn’t always been as cold as it is now. Before Captain Scott and his team perished during their return journey from the South Pole in 1912, they had collected a number of important fossils from near the Beardmore Glacier in the Transantarctic Mountains. When this collection was retrieved and analysed, it was found to contain fossils of an ancient ‘seed-fern’ tree (Glossopteris). Not only did this prove that the continent must have been much warmer in the past to support such vegetation, but the similarity with Glossopteris fossils found in South America, South Africa, and Australia gave strong support to the emerging idea, championed by Alfred Wegener, that the continents were once joined and have since moved apart – the theory of ‘continental drift’.During the 1960s, the mechanisms behind continental drift finally became understood and our modern theory of plate tectonics was born. As with other continents, sea floor spreadingin some places and subduction in others has caused Antarctica’s position to change over geological time; and hence Antarctica hasn’t always been located over the South Pole. Indeed in the distant geological past, the pattern and configuration of tectonic plates has been very different from today. For example, about 450 million years ago the crust that makes up England was in the Southern Hemisphere while crust making up Antarctica straddled the equator!Some 200 million years ago, Antarctic continental crust was joined with South American, African, Indian, and Australian continental crust making up a large southern land mass known as Gondwana (the southern part of the supercontinent called Pangea). After this time, Gondwana slowly split apart to create Antarctica as a separate continent, and Antarctica has gradually moved away from the other southern continents towards its present polar position.

Using relative dating techniques, give a relative age for the fault in Figure 13-1?
Fault occured sometime between units ________ & ________.
Answer:Despite seeming like a relatively stable place, the Earth's surface has changed dramatically over the past 4.6 billion years.
Explanation:Despite seeming like a relatively stable place, the Earth's surface has changed dramatically over the past 4.6 billion years. Mountains have been built and eroded, continents and oceans have moved great distances, and the Earth has fluctuated from being extremely cold and almost completely covered with ice to being very warm and ice-free. These changes typically occur so slowly that they are barely detectable over the span of a human life, yet even at this instant, the Earth's surface is moving and changing. As these changes have occurred, organisms have evolved, and remnants of some have been preserved as fossils.
Outsourced industrial production in less-developed countries often relies on female labor because.
The outsourced industrial production relies on female labor in less developed countries because : Wage rates for women are much lower than for men.
What is wage rate?Wage rate refers to the amount of base wage paid to a worker per unit of time (as per hour or day) or per unit of output if on piecework.
In less developed countries, employers of labor employ more females compared to males due to lower wages that will be paid to the females.
Hence, the outsourced industrial production relies on female labor in less developed countries because wage rates for women are much lower than for men.

Are summers in the northern hemisphere getting longer?
Answer:
Yes
Explanation:
As the Earth circles the Sun during the year, half of the Earth get more or less sunlight than the other half of the Earth. In the summer months, the northern half of the Earth, where we live, tilts towards the Sun. This means we get more sunlight, making the days longer.
The summers in the Northern Hemisphere getting longer, due to the change in the climate.
What is climate change?Long-term changes in climate and weather systems are referred to as climate change.
Although these changes are natural, human operations have been the primary driver of temperature change since the 1800s, owing to the combustion of fossil fuels which releases heat-trapping gases.
During the year, as the Earth circles the Sun, half of the Earth receives more or less sunlight than the other half. The northern half of the Earth, where we dwell, tilts towards the Sun during the summer months. This means we get more sunlight, which lengthens the days.
Therefore, the summers in the Northern Hemisphere getting longer.

Square ABCD has vertices at A (1, 2) and B (3, -3). What is the slope of segment BC?
the slope of CB is 2/5
Explanation:
the slope of AB is -3-2/3-1
=-5/2
the slope of AB*Slope of BC =-1
-5/2 * slope of bc =-1
slope of bc =2/5
The slope of the segment of the square, BC is 2/5.
What is meant by the slope of a segment ?The slope of a segment is defined as the measure of steepness of that segment. It is the ratio of change in y-coordinates to that of x-coordinates.
Here,
The coordinates of A = (1, 2)
The coordinates of B = (3, -3)
Since, ABCD is a square, the slope of BC will be perpendicular to the slope of AB.
So, slope of AB x slope of BC = -1
The equation for slope of a segment is given as,
Slope = (y₂ - y₁)/(x₂ - x₁)
So, slope of AB = (-3 - 2)/(3 - 1)
Slope of AB = -5/2
Therefore,
Slope of BC = -1/slope of AB = -1/(-5/2)
Slope of BC = 2/5
Hence,
The slope of the segment of the square, BC is 2/5.

What is the Equator?A ring that circles a planet or other celestial body's axis is said to be its equator. The northern and southern hemispheres are separated by the Equator. The South Pole is 90 degrees S latitude, and the North Pole is 90 degrees N latitude.
With a latitude of 0 degrees, it is midway between the north and south poles. All year long, the climate is warm in towns and cities near the equator. The reason for this is that the sun is nearly always straight overhead.
The Equator is the place on Earth where it is the largest. The Equator heats up more quickly than the poles because sunlight strikes a smaller surface area there. There are few seasonal temperature variations close to the equator.
