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.

A maria is a term used by geologists to describe the cooled lava pools on the surface of a crater. The lava flows in maria are defined by craters, ridges, faults, and straight and meandering valleys known as rilles.
What is lava cooled?Extrusive igneous rock, commonly known as volcanic rock, occurs when lava flows from a volcano and cools quickly.
Crystals within solid volcanic rocks are small because they don't have much time to form before the rock cools completely, stopping the crystal growth.
Thus, maria is the lava cooled on surface of crater.

Sadie is drawing a timeline in order to compare the relative length of four major divisions of time throughout Earth's history. In order to draw her timeline to scale, she is using the information in the table below.
On her timeline, she plans to represent the Cenozoic era using a line that is 0.35 cm long, and the Mesozoic era using a line that is approximately 1 cm long. Based on these proportions, approximately how long should she draw the line representing the Precambrian?
A. 2 cm
B. 5 cm
C. 20 cm
D. 10 cm
Answer:The Answer is C
Explanation:
In order to compare the relative length of the four divisions of time, Sadie is most likely using the data in the duration column of the data table. Given that the Precambrian lasted for 3,956 millions of years, which is approximately 20 times longer than the Mesozoic era (186 million years), the line she draws should be approximately 20 cm long.
What is a Natural Resources?
Natural resources are naturally occurring materials that are useful to man or could be useful under conceivable technological, economic or social circumstances or supplies drawn from the earth, supplies such as food, building and clothing materials, fertilizers, metals, water and geothermal power. For a long time, natural resources were the domain of the natural sciences.
Based on the availability are two types of natural resources:★Renewable: resources that are available in infinite quantity and can be used repeatedly are called renewable resources. Example: Forest, wind, water, etc.
★Non-Renewable: resources that are limited in abundance due to their non-renewable nature and whose availability may run out in the future are called non-renewable resources. Examples include fossil fuels, minerals, etc.

to what extent is climate change the result of human actions use figure 4 and your own understanding [9 marks +3SPaG]
Answer:
During a recent congressional hearing, Rick Perry, the US energy secretary, remarked that “to stand up and say that 100% of global warming is because of human activity, I think on its face, is just indefensible”.
However, the science on the human contribution to modern warming is quite clear. Humans emissions and activities have caused around 100% of the warming observed since 1950, according to the Intergovernmental Panel on Climate Change’s (IPCC) fifth assessment report.
Here Carbon Brief examines how each of the major factors affecting the Earth’s climate would influence temperatures in isolation – and how their combined effects almost perfectly predict long-term changes in the global temperature.
Carbon Brief’s analysis finds that:
Since 1850, almost all the long-term warming can be explained by greenhouse gas emissions and other human activities.
If greenhouse gas emissions alone were warming the planet, we would expect to see about a third more warming than has actually occurred. They are offset by cooling from human-produced atmospheric aerosols.
Aerosols are projected to decline significantly by 2100, bringing total warming from all factors closer to warming from greenhouse gases alone.
Natural variability in the Earth’s climate is unlikely to play a major role in long-term warming.
US Energy Secretary Rick Perry stated at a recent congressional hearing that it is "simply absurd" to "stand up and argue that 100% of global warming is because of human activity."
What is global warming?The phenomenon of rising average air temperatures close to the surface of the Earth over the previous one to two centuries is known as global warming.
Since the middle of the 20th century, climate scientists have accumulated extensive data on a variety of weather events and their impacts on the climate.
These findings show that Earth's climate has changed on almost every possible timescale since the beginning of geologic time and that human activities have increasingly affected the pace and scope of current climate change since the beginning of the Industrial Revolution.
Many climate scientists concur that if the global average temperature increased by more than 2 °C (3.6 °F) in such a short period of time, serious societal, economic, and ecological harm would result.
The so-called greenhouse effect, which causes the Earth's surface and lower atmosphere to warm due to the presence of water vapor, carbon dioxide, methane, nitrous oxides, and other greenhouse gases, has grown in intensity, which is the cause of modern global warming.

Answer:70
Explanation:
It is important to remember that a protractor is a measuring instrument that is used to measure angles in degrees. Then, in order to measure an angle in degrees using a protractor, you can follow these steps:
1. You must place the center point of the protractor on the vertex of the angle.
2. Then, you must line up the baseline of the protractor with one side of the angle.
3. Finally, you can read the angle in degrees. In this case, you can observe in the image attached that the protractor is placed on the vertex "H" of the angle JHG. Therefore, based on the explanation shown before, you can identify that the measure in degrees of the angle JHG is the following: m\angle JHG=70\°

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.
