Sea floor sediments provide useful climate data because they contain various proxies that can be analyzed to reconstruct past climate conditions.
Foraminifera: These microscopic marine organisms have shells made of calcium carbonate. Different species thrive under specific environmental conditions, such as water temperature and salinity. By studying the composition and distribution of foraminifera in sediment cores, scientists can infer past climate variables.
Oxygen Isotopes: The ratio of oxygen isotopes (O-18 to O-16) in the shells of foraminifera and other organisms reflects the temperature and isotopic composition of the water they lived in. Analysis of sediment cores can provide insights into past temperature changes.
Pollen: Pollen grains from terrestrial plants can be transported by wind or rivers and deposited in marine sediments. By identifying and quantifying pollen types, scientists can reconstruct past vegetation and infer climate conditions.
Geochemical Tracers: Chemical elements, such as carbon, nitrogen, and trace metals, can be used as indicators of past climate and environmental conditions. Changes in their abundance or isotopic composition can provide information about temperature, productivity, ocean circulation, and other factors.

What is another animal that might have a larger than natural population because of human impact? Explain your reasoning.
Cows are probably an animal that is overpopulated because of the human species. This is happening because people need cows for what they can offer, such as milk or even food as a result they keep pushing the limits to get the most out of these animals.
Various animals might have a larger than natural population because of human impact; one is a domestic dog.
Through the human activities of using dogs as a pet, the population of dogs might have a larger than natural population.
The reason is simple, the demand for the dogs as pets would make humans breed dogs, thereby ensuring dogs have more births than a natural occurrence.
This is evident in a recent research survey conducted among pet owners.
It was revealed in 2017 that there are about 89.7 million domestic dogs in the United States.
This number revealed a 20 million increase in domestic dogs population compared to 68 million domestic dogs in 2000.
Hence, in this case, it is concluded that some human activities can positively impact the animal population.

A plane leaves Charlottetown, PEI at 12:00pm on Saturday, May 2nd. The destination is Yellowknife, NWT. The flight takes 17 hours. What is the date and time of your arrival in Yellowknife?
Answer: 5am on Sunday, May 3rd.
Explanation:
Plane left at 12pm and takes 17 hours.
Add 12 and 17:
= 12 + 17
= 29
There are 24 hours in a day. The number of hours into the next day is therefore:
= 29 - 24
= 5 hours
If the plan arrives 5 hours into the next day, that would mean that it arrived at 5am. Date of the next day is May 3rd, a Sunday.

1. What should you do if you feel an earthquake happening?
2. Explain why a rural area might be a safer place to experience an earthquake than a large city.
3. Describe the three kinds of waves that are produced in an earthquake.
Answer:
Ans.1. If you are indoors, drop and take cover under a sturdy table or other furniture. Hold on to it and stay put until the shaking stops.
Stay clear of items that can fall and injure you, such as windows, fireplaces and heavy furniture.
Stay inside. You may be injured by breaking glass and falling objects if you run outside.
If you are at the coast, walk to higher ground away from the ocean as soon as it is safe for you to move.
If you are driving, move your car as far out of the normal traffic pattern as possible and stop if it is safe. Stay away from structures or objects that could fall on you, such as bridges, overpasses, light posts, power lines or trees. Stay inside your car.
If you are in the mountains, or near unstable slopes, be alert for falling rocks, trees or landslides that could be loosened by the earthquake.
Ans.2.Rural/Urban area: Rural areas have fewer people and fewer buildings so the size of the disaster is smaller. Distance from the epicentre: The closer a town or city is from the epicentre the more damage will be caused because of the strong seismic waves.
Ans. 3 There are three basic types of seismic waves – P-waves, S-waves and surface waves. P-waves and S-waves are sometimes collectively called body waves.

because less infrastructure is needed
b. Feedlots require more space than cattle ranching does, which reduces profits due to the cost of

C. Consumers prefer to pay higher prices for grass-fed beef than for corn-fed beef raised in
feedlots because of the environmentally friendly practices associated with grass-fed beef.
d. Feedlots can minimize costs associated with livestock production because feedlots do not use
as much space as cattle ranching
e Feedlots require less food consumption by the cows than cattle ranching because the livestock
are grazing on available grass in the pastures

Volcanic eruptions are catastrophic events that can lead to loss of life. Which measure should people living near the region of an active volcano take to minimize the loss of life?
Question 10 options:
a.Install devices to monitor the levels of gases emitted by the volcano.
b.Build houses with no vents to avoid contact with lethal gases.
c.Use seismographs to predict volcanic eruptions.
d.Build tall houses with steel reinforcements to withstand tremors.
Answer:
Option C, Use seismographs to predict volcanic eruptions
Explanation:
People living near volcanoes proximity are at high risk during the eruption period of volcanoes. As the volcano erupts it releases harmful gases and also the hot molten lava flows out of it thereby disrupting every thing that comes in its way.
If people living in such areas are able to get pre information of volcanic eruptions then they can get time to shift to new safer place.
Hence, option C is correct
