The main method for determining temperatures prior to the instrumental record at Mauna Loa is Examining air bubbles trapped in ancient ice. The correct answer is "A".
Examining air bubbles trapped in ancient ice is a widely used method for reconstructing past temperatures. By extracting ice cores from locations such as glaciers and ice sheets, scientists can analyze the air bubbles trapped within the ice layers. These air bubbles contain samples of the atmosphere at the time the ice was formed, including the composition of greenhouse gases. By measuring the isotopic composition and concentrations of gases like carbon dioxide, methane, and oxygen, scientists can estimate past temperature conditions.
This method is particularly effective for studying long-term climate variations over hundreds or thousands of years. Other options provided, such as organisms in sea floor sediment, tree rings, and historical documents, can provide valuable information for studying different aspects of the Earth's climate history but are not the primary method for determining temperatures prior to the instrumental record at Mauna Loa.

A supernova remnant is now 2.65 pc in radius and is expanding at 4,100 km/s. Approximately how many years ago did the supernova occur? (Note: 1 pc = 3.1 ✕ 1013 km and 1 yr = 3.2 ✕ 107 s.) years ago
A supernova remnant is now 2.65 pc in radius and is expanding at 4,100 km/s. Approximately 625 years ago the supernova occur.
We have the given data of a supernova remnant as the radius and the velocity of expansion. We need to find the time since the occurrence of the supernova. The time when a supernova occurred can be calculated from the current radius of the supernova remnant and its rate of expansion.
In the given scenario, a supernova remnant has a radius of 2.65 pc, and it is expanding at a rate of 4,100 km/s.
The equation to find the distance covered by the supernova remnant after a time t is given as:
r = vt
where
r is the distance covered
v is the velocity
t is the time
Therefore, the time taken to travel a distance r at a velocity v is given as:
t = r/v
Here, we have the radius as 2.65 pc and the velocity as 4100 km/s. The radius needs to be converted into km as the velocity is in km/s.
1 pc = 3.1 × 1013 km
So,
2.65 pc = 2.65 × 3.1 × 1013 km
= 8.215 × 1013 km
Now, we have:
r = 8.215 × 1013 km
v = 4100 km/s
Substituting the values in the formula we get:
t = r/v
= (8.215 × 1013 km) / (4100 km/s)
= 2 × 1010 s
Now, we need to convert this time into years.
1 yr = 3.2 × 107 s
Therefore, the time in years
= 2 × 1010 s / (3.2 × 107 s/yr)
≈ 625 years
Thus, the supernova occurred approximately 625 years ago.

Of the options below, which is an example of a point source of water pollution? a. Salt from road de-icing is swept into the city's storm sewers. b. A housing development is built over a garbage dump that was buried and abandoned c. A rainstorm flushes litter and pet waste from surrounding parks into a nearby lake. d. Fertilizers and pesticides from the valley's farming operations seep into groundwater
The correct answer is a. Salt from road de-icing is swept into the city's storm sewers.
A point source of water pollution refers to a specific and identifiable location where pollutants enter a water body. In this case, the salt from road de-icing being swept into the city's storm sewers is a clear example of a point source of water pollution. The source of pollution, in this case, is localized and can be traced back to the specific location where road salt is applied. The storm sewers act as a conduit, carrying the saltwater runoff directly into nearby water bodies, such as rivers or lakes, leading to potential water pollution.
The other options listed do not represent point sources of water pollution.
b. A housing development built over a garbage dump represents a potential source of groundwater contamination but is not a point source that directly releases pollutants into a specific water body.
c. A rainstorm flushing litter and pet waste from surrounding parks into a nearby lake is an example of non-point source pollution, as it involves the runoff from a larger area rather than a specific point of discharge.
d. Fertilizers and pesticides seeping into groundwater from farming operations represent a diffuse source of pollution rather than a specific point source.

The moon is getting farther away from the sun (angles, not distances). After 2 weeks, the Moon will be AFTER Full. You would not be able to see the Moon at Sunset then.
Sunrise, however, you could see the Moon.
Explanation:It is impossible for the moon to get closer to the sun since the moon orbits the Earth. The Earth orbits the sun, which creates an apparent angle between the Moon and the Sun that changes throughout the lunar cycle.
This angle changes every day, making it appear as though the Moon is moving closer or further away from the Sun in the sky.The Full Moon occurs when the Moon is on the opposite side of the Earth from the Sun. After two weeks, the Moon will be on the same side of the Earth as the Sun.
This means it will be a New Moon, and you will not be able to see it at sunset. At sunrise, however, you could see the Moon since it will be visible in the morning sky before the Sun rises.

Only about 5% of American Christians believe the Bible is inerrant and if it says God created the sun and the moon on a certain night that word does not mean ages it's not a symbol, it means night. So the correct choice is option E.
Only about 5% of American Christians believe the Bible is "inerrant," meaning they view it as without error or contradiction. If the Bible states that God created the sun and the moon on a certain "day," the word "day" in this context is not symbolic but refers to a literal 24-hour period. This perspective emphasizes a literal interpretation of the biblical text, asserting that each day of creation corresponds to a 24-hour period.
However, it is important to note that interpretations of the Bible vary among different individuals and religious groups. Some Christians may interpret the word "day" as representing longer periods or symbolic of different phases of creation. This diversity of interpretations arises from differing theological perspectives, hermeneutical approaches, and cultural contexts. The belief in the inerrancy of the Bible and the interpretation of biblical passages can significantly influence an individual's worldview, understanding of creation, and how they reconcile scientific knowledge with religious teachings.

8. *what are the disadvantages of using a 5 year running average for temperature?
The disadvantages of using a 5 year running average for temperature is that the graph's plots don't show the exact point where the temperature was recorded but rather more of an average of the years close to that point.
Through changes in distribution of species and population structure, rising temperatures have an impact on all types of ecosystems and raise the possibility of extinction for some species. Crop output may be impacted by these changes, which may also influence ecosystem services like carbon storage. Aridity and droughts are inevitably more likely with rising temperatures.
Since annual mean temperature changes can act as a proxy for changes in a variety of heat- and cold-related risks, they are frequently employed as the flagship index for regional climate change assessments. The management of forests and ecosystems, energy consumption, and many other sectoral uses are directly impacted by changes in seasonal mean temperature.
