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.

Subsistence farming presents a large problem for rural farming families if their crops are not successful. true false
Subsistence farming is a style of farming in which almost all of the crops or cattle raised are used to maintain the farmer and his or her family, with little or no surplus for sale or trade.
What are the advantages of subsistence farming?Subsistence farming appeals to rural farmers primarily because it supplies them with sufficient food, reduces transportation costs to cities, and needs to continue living in rural locations where life expenditures such as housing and land are more reasonable.
Subsistence/smallholder Farming can help to reduce the risk of rural and urban food-insecure households, improve livelihoods, and aid to offset high food price inflation.
Thus the statement is True.

The radioactive isotope content of a rock can be used to identify which property of the rock?.
Answer:
The radioactive isotope content of a rock can be used to identify the rocks age.
The radioactive isotope content of a rock can be used to identify the rocks age.
What is radioactive isotope?Any of multiple species of the same chemical element with varying masses whose nuclei are unstable and spontaneously emit radiation in the form of alpha, beta, and gamma rays to waste excess energy is referred to as a radioactive isotope, radionuclide, or radioactive nuclide.
The nuclear decay of radioactive isotopes is a clock-like process and thus a useful tool for determining the absolute age of rocks. These isotopes decay within the rocks according to their half-life rates, and the date at which the rock crystallized can be determined by selecting the appropriate minerals and measuring the relative amounts of parent and daughter isotopes in them.
Therefore the age of the rock can be identified by the use of the radioactive isotope.

Explain how climate influences the distribution of biomes in different regions
Answer:
Climate influences the distribution of biomes in different regions because of the temperature and precipitation. Mostly or generally speaking most biomes at higher latitudes or the ones that are farther away from the equator are drier and/or cooler. So this explains that the distribution of species in new areas might influence it.

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.

This is a cycle because it continues forever. Cycles like for example, a human. A human starts off as a baby, becomes a toddler., then ages into a kid then a teenager, afterwards an adult. And this cycle continues. It happens everywhere in nature and everywhere in the world today with living things including: Plants, Humans, and animals. I hope this helps It might be wrong and I'm sorry if it is:(
Answer:
plants need carbon dioxide and animals need oxygen
Explanation:
they depend on each other so when one is using oxygen the other is using carbon that way too much or too little of one is used.
