Globular clusters rarely contain blue giant stars, because the clusters are: a. metal poor b. young c. distant d. stable e. old
Answers
The correct answer is (e) old. Globular clusters are some of the oldest structures in the universe, with an estimated age of around 10-13 billion years.
As a result, the stars within them have had plenty of time to evolve and age, and blue giant stars (which are very massive and short-lived) have typically already gone supernova or evolved into cooler, smaller stars. Additionally, globular clusters are known for being metal poor, which can further limit the formation of blue giant stars. Globular clusters rarely contain blue giant stars because the clusters are: e. old. This is due to the fact that blue giant stars have relatively short lifespans, and most of them have already evolved or died within the older globular clusters. The correct answer is e. old. Globular clusters are some of the oldest structures in the universe, with an estimated age of around 10-13 billion years.

Explain how the magnetic stripes form on the ocean floor.
Answers
Answer:
The striped magnetic pattern develops because, as oceanic crust pulls apart, magma rises to the surface at mid-ocean ridges and spills out to create new bands of the ocean floor. ... Later, after the planet's magnetic field flips again, the next stripe of new ocean floor aligns its polarity in the opposite direction.

The correct answer would be number D!! I just took the quiz it’s correct
The type of telescope Sarah used is radio telescope. The correct option is A.
What is a radio telescope?A radio telescope is a specialized antenna and radio receiver that detects the radio waves from the celestial radio sources.
Radio telescopes detect and amplify radio waves from space, converting them into the signals that astronomers can use to learn more about the Universe.
A radio telescope scans across an object, picking up radio waves from each tiny spot in space around it. Some locations may emit the stronger radio waves than others. Pixels are used to store this data/information. This data is turned into statistics by the virtual machine.
The Event Horizon Telescope, an array that linked together eight existing radio observatories around the whole world to form a single Earth-sized virtual telescope, captured it. Thus, the correct option is A.

Rocky material from the earth's interior can reach the surface, and be pushed and folded upward during the process of _______. One of the processes that works to return this material back to the earth's interior is _______.
Answers
Rocky material from the Earth's interior can reach the surface, and be pushed and folded upward during the process of mountain building. One of the processes that work to return this material to the Earth's interior is erosion.
The process of mountain building is known as Orogenesis. The Greek word Orogenesis is derived from Oros means mountain and Genesis mean formation. Due to the tectonic movements sometimes the earth's interior materials are pushed to the earth's surface and get folded and rise upward this is known as mountain building. In this way, fold mountains are formed.
When the newly formed folded structure undergoes some sort of changes due to the erosional activities by the agents of nature like air, water, glacier, etc. known as erosion.

1.What is the nature of the boundary between the Redwall limestone and supai group
A paraconformity
b.A disconformity
c.A nonconformity
d.An angular unconformity
Answers
c. A nonconformity , A nonconformity is a type of unconformity, which is a break or gap in the rock record that represents a period of erosion or non-deposition.
In the context of geology, a nonconformity occurs when sedimentary rocks overlie crystalline or metamorphic rocks with an erosional surface in between.
In other words, it is a contact between younger sedimentary rocks (such as the Redwall limestone) and older rocks (such as the crystalline or metamorphic rocks of the Supai Group) that have been uplifted and exposed to erosion before the younger rocks were deposited on top.
A paraconformity is a type of unconformity where the contact between the two sets of rocks is parallel, indicating a period of non-deposition without significant erosion.
A disconformity is an unconformity where the contact between the two sets of rocks is horizontal, indicating a period of erosion and non-deposition.
An angular unconformity is an unconformity where the contact between the two sets of rocks is tilted or folded, indicating a period of deformation and erosion before the younger rocks were deposited.
Based on the given options, a nonconformity (option c) would be the most likely nature of the boundary between the Redwall limestone and Supai Group, as it would represent an erosional surface between younger sedimentary rocks and older crystalline or metamorphic rocks.
