If a mineral has a parent to daughter ratio of 1:3 (one parent atom for every three daughter atoms), how many half-lives have passed since the mineral formed?
a. 0
b. 1
c. 2
d. 3
e. 4
Answer:
c. 2
Explanation:
Given that
Parent to daughter ratio = 1:3
Based on the above information, after considering the 1 half-life of radioactive isotope there is one-half of the real radioactive atoms of the parent left also the equivalent number of daughter atoms produced
Therefore after one half, the ratio between parent and daughter atom is 1:1
Now after the second half, half of the left parent atom would be transformed into the daughter cells
This remains a quarter of parent atom and 3 quarter of daughter atoms
So, the ratio of 1:3 would be shown after 2 half-lives

A scientist determines that "Crystal Volcano" is 5,000 years old. What can that scientist assume about the ages of three other nearby volcanoes
Answer:
The answer to the question is as follows.
Explanation:
Two major decisions can be taken by examining volcanic stones.
Because the volcanoes were formed by subsidence, they would probably be around the same age. When a hot spot has produced the volcanic activity, the age groups of all the other volcanoes depend on the situation of the Crystal Volcano in the chain.If you are flying over a mountain and see sedimentary layers making an outline in the shape of an overturned cereal bowl, the feature would be called a(n)
Answer:
Dome
Explanation:
A dome is known as a structure with a curved shape like the shape of a half sphere and is also not perfectly round.
When flying over a mountain and see sedimentary layers making an outline in the shape of an overturned cereal bowl. The overturned cereal bowl seen assumes the shape of a dome in the explanation given above . This validates the outline being that of a dome.

The discontinuity separating the crust from the mantle is named as: A.Mohorovicic B.Conrad C.Reppetty D.Gutemberg
Answer:
A.mohorovic
Explanation:
The Mohorovičić discontinuity (/moʊhəˈroʊvɪtʃɪtʃ/ MOH-hə-ROH-vitch-itch, Croatian: [moxorôʋiːtʃitɕ]),[1] usually referred to as the Moho discontinuity or the Moho, is the boundary between the Earth's crust and the mantle. It is defined by the distinct change in velocity of seismological waves as they pass through changing densities of rock.[2]
The Moho lies almost entirely within the lithosphere.[3] Only beneath mid-ocean ridges does it define the lithosphere–asthenosphere boundary. The Mohorovičić discontinuity is 5 to 10 kilometres (3–6 mi) below the ocean floor, and 20 to 90 kilometres (10–60 mi) beneath typical continental crusts, with an average of 35 kilometres (22 mi).
Named after the pioneering Croatian seismologist Andrija Mohorovičić, the Moho separates both the oceanic crust and continental crust from underlying mantle. The Mohorovičić discontinuity was first identified in 1909 by Mohorovičić, when he observed that seismograms from shallow-focus earthquakes had two sets of P-waves and S-waves, one that followed a direct path near the Earth's surface and the other refracted by a high-velocity medium.[4]

A climate classification based on the geographic determinants of climate, such as latitude or elevation, is an example of a(n)'
Answer:
Genetic classification.
Explanation:
The genetic classification of climate is based on determinants of climate such as, location with respect to wind and pressure belts, latitudinal control of temperature, effects of mountains.
Genetic classification also relies on information about climatic elements like solar radiation, air masses, and pressure systems.
This classification is qualitative and climate is designated in a subjective manner with no rigorous scientific research done.

The transformation of snow into glacial ice in Antarctica takes ________ than (as) in midlatitude alpine glaciers because ________. Group of answer choices
Answer:
The answer is "longer; and In polar regions, fewer snowstorms are per year, and in Antarctica, less melting and refreezing tend to occur".
Explanation:
The Antarctic consists of several glaciers, land ice, and icebergs, in which There have been no trees or shrubbery, the Moss and algae are the only plants, that survive in a cold place.
The conversion of polar ice throughout Antarctica for moderate ice caps, which takes much longer time than a snowstorm is reduced per year, that's why it is the less cooling, and refrigeration is observed in Antarctica.
If you were to examine the longitudinal profile of a typical river, you would probably find that the gradient is ________.
Answer:
steepest near the headwaters.
Explanation:
Stream Gradient is the slope-drop over distance. Stream gradient can be defined as a drop of stream in vertical line and falling over a horizontal distance.
The steam gradient, if we examine the longitudinal profile of a typical water, will be steepest near the headwaters. The stream gradient is steepest near the headwaters whereas gentle at the mouth. After the stream reaches at the mouth it gets discharged into another water body.
So, the correct answer is that the stream gradient is steepest near the headwaters.
The longitudinal profile of a typical river, we will find that the stream gradient is steepest near the headwaters.
What is stream gradient?Stream Gradient is a slope drop by distance. Stream Gradient can be defined as the drop of stream in a vertical line and falling over a horizontal distance.
Steam gradient, if we examine the longitudinal profile of normal water, would be very dangerous near the river. The gradient of the stream rises sharply near the headwaters while it is soft in the mouth.
After the stream reaches the mouth it flows into another water source.
Thus, the correct answer is that the stream gradient is steepest near the headwaters.

What major geographical advantage does agriculture in the Coastal South have over most other regions of North America
Answer:
The region is largely frost-free so many frost intolerant crops can be grown.
Explanation:
The Coastal South in North America consists of cities like Florida, Texas, and North Carolina. This region is known for the exceptional agriculture that occurs there. The nature of their soil is not the cause of this, rather it has a lot more to do with their climatic conditions which range from the time of the last frost in spring to the beginning of the next frost in fall. So, this allows for about nine months of intensive agriculture.
Frost is ice which is mostly seen on the surface of the soil. It is quite difficult for many plants to survive the harsh condition imposed by frost. So the lengthy number of days and months without frost in the Coastal South gives it a great advantage over compared to many other regions in North America.

Answer:
daytime solar heating of the surface increases surface temperatures.
Explanation:
Atmospheric stability is the condition where the air is generally considered to be stable than earlier due to the certain changes that take place over the period of time which are associated with the weather and climatic variability.
