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.

Explain Solar Energy.
Answer:
Solar energy is what you get from the sun's radiation and then use that energy produce heat or generate electricity.
Explanation:
Solar energy is defined as the transformation of energy that is present in the sun and is one of the renewable energies. Once the sunlight passes through the earth’s atmosphere, most of it is in the form of visible light and infrared radiation. Plants use it to convert into sugar and starches and this process of conversion is known as photosynthesis. Solar cell panels are used to convert this energy into electricity.
Advantages of solar energy are:1. Clean: It is considered to the cleanest form of energy as there is no emission of carbon dioxide like in case of fossil fuels which is one of the causes of global warming.
2. Renewable: There is an ample amount of energy available on earth as long as the sun exists.
3. Reliable: The energy can be stored in the batteries and so there is no question of unreliability.
4. Free energy because it can be trapped easily.
Disadvantages of solar energy:1. The production is low during winters and on cloudy days.
2. Installation and the initial cost of the materials are expensive.
3. Space consumption is more.

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.

All clouds form due to the warm, moist air __________ then getting to cooler elevations and cooling.
All clouds form due to the warm, moist air rises then getting to cooler elevations and cooling.
Processes of coolingThe warmed air starts to rise because, when warm, it is lighter and less dense than the air around it. As it rises, its pressure and temperature drop causing water vapor to condense. Eventually, enough moisture will condense out of the air to form a cloud. The air cools as it rises, and eventually clouds form.
Therefore, moist air rises then get to cooler elevations and cooling.

Which of the following would not cause habitat change? a. Building a dam on a river b. A hurricane c. Introducing new hiking trails d. None of the above Please select the best answer from the choices provided A B C D.
All the given options would cause habitat change. So, option (d) is the correct answer.
What causes a habitat change?All of the suggested factors are contributing to habitat change, each in their own unique way:
Constructing a dam on a river will halt the natural flow of the river, halting the natural movement of living species, nutrient dissemination, water temperature, and water depth.
Because hurricanes typically do extensive damage, they frequently destroy one habitat while effectively creating space for another to emerge.
Introducing new hiking routes, while minor, manages to induce change in the habitat because specific areas of the habitat must be cleared, essentially destroyed, and also maintained, resulting in a major rise in the number of people, producing environmental disturbance.
