A scientist has a fossil that was found in a layer of rock close to Earth’s surface. He believes that the fossil is around 12,000 years old.
Which method would best allow the scientist to confirm the actual age of the fossil?
-finding another fossil in a deeper layer of rock
-finding another fossil in the same layer of rock
-using carbon/nitrogen absolute dating
-using potassium/argon absolute dating
Answer:
using carbon/nitrogen absolute dating.
Explanation:
A geologic column can be defined as a collection of rock layers that are typically grouped based on their relative ages in a descending order i.e from oldest to the youngest.
Generally, the layers of the rock that are found in various parts of the world are known to be different because they all comprises of distinct Earth's geological history.
A fossil can be defined as the mineral impression or remains of living organisms such as plants and animals that are prehistoric in nature.
In this scenario, a scientist has a fossil that was found in a layer of rock close to Earth’s surface. He believes that the fossil is around 12,000 years old. Thus, the method which would best allow the scientist to confirm the actual age of the fossil is using carbon/nitrogen absolute dating because they are radioactive elements with different isotopes.
In Science, absolute dating can be defined as a process used to accurately determine the age of a rock or fossil by measuring the decay of isotopes associated with the rock or within the fossils. These informations when properly obtained can be used to determine the age of any historical monument or material such as earth, rocks, animals, plants, etc., because the parent material decays into a stable daughter elements at a constant decay rate.
Answer:
using carbon/nitrogen absolute dating.

discuss the effects of global trade on countries
Answer:
Global trade can have many fundamental effects on countries around the world. International trade results in the rapid development of countries and infrastructure. In addition, global trade can introduce new products and materials to countries, increasing development. This exposes countries to a variety of goods and services that were previously unavailable in their domestic economies. Imports from other countries also tend to lower consumer prices, which has a positive effect on global economies. Overall, global trade is central to the economic development of countries worldwide and positively impacts quality of living.

What can be determined about the environment in which this fossil formed?
o
A. It was full of carnivorous organisms that allowed plants to survive and reproduce.
O
B. It experienced a long period of stability that was followed by a mass extinction event
O
C. It was able to support biological diversity, as sunlight and water were both readily available.
OD. It went through a period of rapid climate change, as the leaves on the plant were starting to fall.
Answer:
answer B
Explanation:
fossils form as a reult of different methods. Pressure, absence of decomposers, and sedimentation without signifiacant disturbanses are among the reasons.For these sort of reasons to prevail it should be a hard, adverse climate as of an mass extiction event.

List 3 ways wetlands help the abiotic (non-living) environment.
Answer:
Wetlands such as swamps and bayous have lots of plant and animal life, along with many bacteria, protists, and fungi. All of these, of course, are biotic factors. Some abiotic factors include the soil/mud or sand (not including the living organisms inside of it), rocks, sunlight, water, and gases in the air. There's also a number of chemical components in the water and soil, which can include salts, sulfur, nitrates and nitrites, and ammonia, among others.
Name the three categories of Indus Basin soils.
Answer:
The Indus Basin soils are created by depositing the alluvium by the river Indus and are generally called Indus Basin Soils. These can further be divided into three major groups. First group is known as Bangar soil of alluvium which is very productive when irrigated and fertilized.
This soil covers a vast area in the Indus plain, including most of the area of the Punjab, Peshawar, Mardan, Bannu and the greater part of the Indus Plain. The second group is called Khaddar soil and is formed from the flooded layers of silt, loam and silty clay loam. Such type of soil is commonly found is Mardan and Bahawalpur. This soil is very fruitful for agriculture products when plenty of water is added in to it.
The third group of soil is Indus Delta soil Covering the whole of Indus Delta from south of Hyderabad to the Arabian Sea coast. Before becoming part of the sea, Indus River is distributed here into a number of branches. About one third of the area is covered by clay covered by clay soil which is developed under flooded water conditions. This soil is used for the cultivation of rice.

Answer:
Subduction Zone Volcanism
Most explosive eruptions occur in volcanoes above subduction zones, where one tectonic plate dives beneath the other. Eighty to 120 kilometers below the surface, magma forms when the rocks of the mantle melt just above the subducting plate. The magma rises through the mantle, and erupts to form great composite volcanoes such as Vesuvius. Explosive eruptions have also built arc-shaped island chains such as Indonesia, and continental mountains like the Cascades. In this zone, you will see rocks from all these areas.
Why some volcanoes explode
A volcano’s explosiveness depends on the composition of the magma (molten rock) and how readily gas can escape from it. As magma rises and pressure is released, gas bubbles (mainly of water vapor and carbon dioxide) form and expand rapidly, causing explosions. Magmas with high silica content tend to erupt violently, because they are viscious. They form volcanoes like Krakatau and Tambora in Indonesia, and Mount Rainier and Mount St. Helens in Washington State. In contrast, basaltic magma (which forms the volcanoes of Hawaii and other oceanic islands) contains less silica, is more fluid, and does not erupt in gain explosions.

What causes the trail distance of longshore drift to increase?
Answer:
Longshore currents are affected by the velocity and angle of a wave. When a wave breaks at a more acute (steep) angle on a beach, encounters a steeper beach slope, or is very high, longshore currents increase in velocity. ... This process, known as “longshore drift,” can cause significant beach erosion.

Of the four most abundant gases in our atmosphere, which one shows the greatest variation from place to place at the earth's surface
Answer: Water Vapor
Explanation:
Water Vapor is the third most abundant gas in the atmosphere but shows the greatest variation because in some places it could be so low that it is practically 0% but in other areas it can get up to 4%.
This is because there are areas where it is more conducive for water vapor to exist and places it isn't. For instance, there will be a lot of water vapor in tropical climates where rainfall is abundant as opposed to deserts where temperatures are too high and rainfall too low for rain to come.
