B.
the drifting of the continents
C.
the changes in Earth's magnetic field
D.
a transfer of gases from the Sun
Answers
Answer:
The answer is A
Explanation:
The appearance of oxygen-producing organisms.
The appearance of free oxygen in Earth's atmosphere led to the Great Oxidation Event. This was triggered by cyanobacteria producing oxygen that was used by multicellular forms as early as 2.3 billion years ago.What are cyanobacteria?Cyanobacteria are aquatic and photosynthetic, that is, they live in the water, and can manufacture their own food. Because they are bacteria, they are quite small and usually unicellular, though they often grow in colonies large enough to see.Cyanobacteria are responsible for the Earth's transition from a carbon dioxide-rich atmosphere to the present relatively oxygen rich atmosphere as a consequence of oxygenic photosynthesis.To know more about multicellular here

The two main parts of evolution that Christians often try to reconcile with Scripture are the extent of change in organisms and the timetable of change. Fill in the following table, describing the different views of ori-
gins. The first row has been completed for you as an example.
Answers
Answer:
Explanation:
Why has Darwin’s science been such a religiously troubling idea? In those parts of the world influenced by the Bible and the Qur’an, we may point to at least five reasons: (1) Darwinian biology tells a whole new story of creation, one that cannot be literally reconciled with religious creation stories such as those narrated in the book of Genesis; (2) the evolutionary notion of natural selection seems to eliminate the role of God in creating the various species of life; (3) Darwin’s theory of human descent from nonhuman forms of life raises questions about traditional beliefs in human uniqueness, such as the biblical claim that human beings are created “in the image and likeness of God”; (4) the prominent role of chance or accidents in evolution raises questions about whether a creator truly cares for the world; and (5) the competitive “struggle for existence” inherent in evolution seems at odds with a Universe created by God.
Darwin's theory of human descent from nonhuman forms of life raises questions about conventional beliefs in human uniqueness, such as the biblical claim that human beings are the only species to have evolved from nonhuman life forms.
What kind of evolution that Christians often try to reconcile?Christians frequently attempt to reconcile two key aspects of evolution with Scripture: the pace of change and the scope of organismal change.
Darwinian biology tells a whole new story of creation, one that cannot be literally reconciled with religious creation stories like those narrated in the book of Genesis.
Therefore, the evolutionary notion of natural selection seems to eliminate the role of God in creating the various species of life.

Peat is a mixture of partially decomposed plant and animal material found in waterlogged, acidic, anaerobic environments. people debate whether peat is a fossil
fuel. to be considered a fossil fuel, a material must be of biologic origin, be used as a source of energy, and replenish on a time scale greater than human
lifetimes. peat reserves have declined over time. however, peat harvesters claim that a restoration process
can make peat a renewable resource and allow it to
be classified as a biofuel. the restoration process is outlined in the table.

Based on the data from the restoration process of peat, it can be concluded that peat is a fossil fuel because the total restoration time is lengthy.
What are fossil fuels?Fossil fuels are fuels produced from the remains of dead plants and animals which decomposed under intense heat and pressure over a long period of time.
Fossil fuels are non-renewable energy sources because their time of replenishment is longer than a human lifetime.

how is an increased in carbonin the atmosphere likley to affect coastal areas such as those in north carolina
Answers
Answer:
D
Explanation:
The amount of Carbon dioxide (CO₂) that is trapped in the atmosphere is released by the burning of the fossil fuels and from the industrial pollution. In addition to this, some amount of it also released by the animals and human beings. This stored CO₂ in the atmosphere is then transported to the oceans with the help of rainfall. When this CO₂ reacts with water it forms weaker acid, which is commonly known as the Carbonic acid. Due to this, the pH level of ocean water decreases. As a result of this, it affects the ocean water chemistry and the marine life. Due to this ocean acidification, the marine species namely the corals and various types of planktons are not able to form the hard parts like the shell and skeletal parts. This carbonate water dissolves the existing shells and erodes the particles away. The increase in the carbon content in the atmosphere will also lead to precipitation that will wash away the rock particles and other sediments, that are present in the coastal areas. In addition to this, the plants also will be affected due to this carbon containing water.
