When sedimentary layers are first formed, the sediments fall in horizontal layers

A. Uniformitarianism
B. Principle of faunal succession
C. Principle of superposition
D. Principle of original horizontality

Scientist today believe That as the earth formed different types of life came into being at different times so geologically when fossils found in rock layers are considered it is believed the identification of the fossils can help determine the age of the sedimentary Rock layers the fossils is found in

A. Uniformitarianism
B. Principle of faunal succession

C. Principle of superposition
D. Principle of original horizontality

The belief that the process at work today that shape the face of the earth that where at work in the past it is important to understand that not only did the process occur in the past but they that they occur at the same rate and in the same way

A. Uniformitarianism
B. Principle of faunal succession
C. Principle of superposition
D. Principle of original horizontality

This principle states that in layers of rock that have been undisturbed, Geologist say Undeformed the Lowest layers Formed first is in the next and the next and so on to the top layer that puts the oldest layer on the bottom and the layers get younger and younger as you go up

A. Uniformitarianism
B. Principle of faunal succession
C. Principle of superposition
D. Principle of original horizontality

answer: the correct answer is 1.

explanation: there are various process in which a radioactive nuclei decays:

1) alpha decay: in this process, a heavier nuclei decays into lighter nuclei by releasing alpha particle. the mass number is reduced by 4 units.

2) electron capture: in this decay process, a parent nuclei absorbs an electron and gets converted into a neutron. simply, a proton and an electron combines together to form a neutron. mass number does not change in this process.

3) gamma ray emission: it is a decay process in which an unstable nuclei gives excess energy by a spontaneous electromagnetic process. this decay releases . this process does not change the mass number.

4) positron emission: it is a type of decay process, in which a proton gets converted to neutron and an electron neutrino. this is also known as -decay. in this the mass number remains same.

from the above information, we see that only alpha-decay is producing a change in the mass number of the nucleus.

i don’t know what the answer is i wish i

a

explanation:

no diagram was provided, but i'm guessing it's the one i've attached to my answer.

here, a mechanical force turns the rod.   this generates an electric current in the coil, which powers the bulb.
