Which statement best explains why Lyra is visible to an observer in New York State at midnight in July but not visible at midnight in December?
d. Lyra orbits Earth. Dear student, The correct option is b. The earth orbits the sun.
Which sequence shows the correct order of Earth’s geologic time intervals from oldest to youngest?
Earth’s history is characterized by four eons; in order from oldest to youngest, these are the Hadeon, Archean, Proterozoic, and Phanerozoic.
During which geologic time period did great coal forming forests exist?
Characteristic of the Carboniferous period (from about 360 million to 300 million years ago) were its dense and swampy forests, which gave rise to large deposits of peat. Over the eons the peat transformed into rich coal stores in Western Europe and North America.
Which group of organisms some of which were preserved as fossils in early Paleozoic rocks?
During the Paleozoic Era (541 to 252 million years ago) Fish diversified and marine organisms were very abundant during the Paleozoic. Common Paleozoic fossils include trilobites and cephalopods such as squid, as well as insects and ferns.
Which of the following statements best explains why some stars appear brighter than others?
A star’s brightness also depends on its proximity to us. The more distant an object is, the dimmer it appears. Therefore, if two stars have the same level of brightness, but one is farther away, the closer star will appear brighter than the more distant star – even though they are equally bright!
Which statement best explains why Lyra is visible to an observer in New York State?
This is Expert Verified Answer
Lyra is small constellation occupying an area of 286 square degrees. It is present in the fourth quadrant of north hemisphere and is visible at latitudes between +90° and -45°.
Which of the following is the correct order of the geologic timeline from largest to smallest?
The geologic time scale is divided into (from longest to shortest): eons, eras, periods, epochs and ages.
Which evidence is most likely used to indicate the beginning of solar system formation?
Which evidence is most likely used to indicate the beginning of solar system formation? Materials were pulled together by gravity.
What is the process used by the geologist in order to know the age of the fossils?
radiometric dating methods
To establish the age of a rock or a fossil, researchers use some type of clock to determine the date it was formed. Geologists commonly use radiometric dating methods, based on the natural radioactive decay of certain elements such as potassium and carbon, as reliable clocks to date ancient events.
What is the best inference that can be made concerning the movement of galaxies AB and C?
What is the best inference that can be made concerning the movement of galaxies A, B, and C? Galaxies A, B, and C are all moving away from Earth.
Which rock is metamorphic and shows evidence of foliation?
Slate is a fine-grained metamorphic rock that exhibits a foliation called slaty cleavage that is the flat orientation of the small platy crystals of mica and chlorite forming perpendicular to the direction of stress.
Which processes were primarily responsible for the formation of the sedimentary rock layers shown?
Sedimentary rocks are formed on or near the Earth’s surface, in contrast to metamorphic and igneous rocks, which are formed deep within the Earth. The most important geological processes that lead to the creation of sedimentary rocks are erosion, weathering, dissolution, precipitation, and lithification.
Which method is most likely used to identify what happened before the start of the Paleozoic Era?
Which method is most likely used to identify what happened before the start of the Paleozoic era? Scientists examine fossil evidence during the Precambrian time.
What does fossil evidence reveal about the end of the Paleozoic Era?
During the late Paleozoic, great forests of primitive plants thrived on land; these would form the great coal beds of Europe and eastern North America. By the end of the era, the fossil evidence reveals the first large, sophisticated reptiles and the first modern plants (conifers).
What type of fossil is formed by the preservation of skeletal parts of the organism?
In permineralization, or petrified, fossils, each part of the organism is replaced by minerals, leaving a stone copy of the organism. Bones, teeth and even woody plant materials such as trees are sometimes preserved in this manner.
What evidence indicates that galaxies are moving away from Earth?
The light we observe from galaxies has been stretched by the time it reaches us. It looks redder than it should. This redshift is the result of galaxies moving away from us. Observations show that pretty much everything in the Universe is moving apart.
Which sentence accurately describes star clusters stars appear brighter stars form large groupings stars form at different times stars form from different Nebula?
This is an Expert-Verified Answer. Stars appear brighter – this sentence accurately describes star clusters.
Why do object in the sky appear brighter than the other objects seen at daytime?
In astronomy, there are two things that determine how bright an object appears to be here on Earth; Total amount of light the object gives off (luminosity). How far away the object is.
Which statement best explains the cause of this apparent change in the sun’s path?
Answer: ❥The apparent motion of the sun, caused by the rotation of the Earth about its axis, changes the angle at which the direct component of light will strike the Earth. From a fixed location on Earth, the sun appears to move throughout the sky. Path of the sun in the southern hemisphere.
Which motion causes observers on Earth to see different constellations at different times of the year?
Why Do We See Different Constellations During the Year? If observed through the year, the constellations shift gradually to the west. This is caused by Earth’s orbit around our Sun. In the summer, viewers are looking in a different direction in space at night than they are during the winter.
