List 2 discoveries from Thomson's experiment.
Explain how plate boundaries are connected to the slow movement of solid rock in the mantle.
The movement of warmth by convection within the layer causes the rock of the mantle to slowly move in large streams. The solid rock of the layer is resting directly on high of the solid rock of the layer.

Early embryological studies
During the four decades after Cuvier, embryological studies of all classes of vertebrates clarified the homologies of the middle ear structures, which, prior to Owen (1843), were more usually referred to as analogies. Carus (1818) had doubted that the articulation of the lower jaw is identical between mammals and the other vertebrates, and he recognized that the incus (anvil) is homologous to the quadrate of ‘lower’ (i.e. non‐mammalian) vertebrates. Meckel (1820) observed that, in mammals, the embryonic malleus (hammer) develops from the posterior end of a thin rod of cartilage attached to the medial side of the dentary, whereas in non‐mammalian vertebrates this posterior end ossifies as the articular bone; Meckel therefore homologized the malleus with the articular. The embryonic cartilage of the lower jaw is now called ‘Meckel's cartilage’ after its discoverer. These discoveries replaced some earlier homologizations, such as those of Geoffroy‐Saint‐Hilaire (1818).
These finds gained a new importance when Rathke (1825a,b) described Kiemenspalten (gill slits) and Kiemenbögen (gill arches) in embryos of the pig and chick. The discovery of Kiemen‐Anlagen (gill anlagen) stimulated a number of similar studies on many different amniotes, including man. These early studies suggested that the most anterior of the Kiemenbögen represents the mandibular arch and that the second represents the hyal arch (Baer, 1828). The term Kiemenbogen was accordingly replaced by the more general terms Visceralbogen (visceral arch) or Schlundbogen (pharyngeal arch). Huschke (1827, 1828) concluded that the first cleft between the mandibular and the hyal arches (Spritzloch = spiraculum) corresponds to the ear duct (Gehörgang = Eustachian tube, middle ear, and outer ear).

The Reichert–Gaupp theory
Carl Reichert, who had mainly studied the embryogenesis of the second visceral arch (cf. cartilage of Reichert), in 1837 summarized and generalized his own findings and those of colleagues such as Meckel (1820), Carus (1818), Rathke (1825a,b) and Baer (1828). Since then these concepts have (not quite correctly) been collectively referred to as ‘Reichert's theory’. The numerous and often controversial publications were carefully reviewed and summarized by Gaupp (1898), Broman (1899), and Van der Klaauw (1924).
The homology of the incus and malleus with the quadrate and articular, respectively (Fig. 1A) was accepted by most authors, but Huxley (1869) and Parker (1874, 1877) maintained different views: they derived only the malleus from the mandibular arch and aligned the incus with the second visceral or hyal arch. Establishing the homology of the stapes proved to be more complicated, the more so because it was difficult to compare it among different tetrapod groups. Reichert (1837) had homologized the stapes with the columella of amphibians, but he did not precisely define what he meant by ‘columella’ because he did not distinguish an extracolumella (Reichert, 1838). Huxley (1869) and Parker (1874, 1877) considered the stapes as an element isolated from the lateral wall of the labyrinth capsule (see section below on developmental biology). Broman (1899) showed conclusively that the human stapes chondrifies as an ‘annulus stapedius’, which is in contact with the hyal arch (cartilage of Reichert) by means of an interhyal blastema. The ‘annulus stapedius’, which often forms around the stapedial artery, comes into contact with the wall of the labyrinth only later and forms a fenestra ovalis (vestibuli) secondarily. Therefore, embryological evidence clearly supported the case that the stapes is the most proximal portion of the hyal arch (Fig. 1A, see also section on developmental biology). Gaupp (1898) adopted this view contra his earlier viewpoints and these homologies of the three middle ear ossicles were also accepted by Gegenbaur (1898).

How did Jackie Robison advocate for black advancement during the Jim Crow era
Answer: In his first year with the movement, Jackie crisscrossed the country and helped to raise $1 million for the NAACP. By the early 1960s, Robinson raised money for SCLC by hosting jazz concerts in his backyard. The funds were raised to help provide bail money for the jailed activists.
Jackie and his family also participated in Civil Rights marches. He was on the front line during the famous “March on Washington” on Aug. 28, 1963, that culminated with King’s unforgettable “I Have a Dream” speech.

Explanation:
A student is comparing the three types of celestial bodies, comets, asteroids, and meteor. Which questions would yield the most
information about a celestial body passing close by the Earth and why? Select ALL that apply.
A)
Is the object larger than 5 km in width? If so, it is a meteor.
B)
Is the object made of ice and dust? If so, it is likely a comet.
Is the object comprised of mostly gas? If so, it is likely an asteroid.
D)
Is the object between Mars and Jupiter? If so, it is likely an asteroid.
Is the objecta smaller piece broken from a larger body? If so, it is likely a
E)
meteor
Answer:
Is the object made of ice and dust? If so, it is likely a comet.
Explanation:
Comets are the bodies of the solar system that have the smallest diameter in relation to other bodies. Each comet has its divinity structure in the nucleus, hair and tail and its composition is composed of rock, dust and ice. This ice is quite dirty, because of all the dust and can make up most of the comet, reaching dozens of tons, but it can also be presented in smaller quantities.
B) is the object made of ice and dust? if so, it is likely a comet
D) is the object between Mars and Jupiter? if so, it is likely an asteroid
E) is the object a smaller piece broken from a larger body? if so, it is likely a meteor

Which photo shows no evidence that the rock has been deformed by
movements of Earth's crust?
A.
O
D.
Answer:
C
Explanation:
Image C shows horizontal layers of rock that are undisturbed and appear flat. There are no signs of folding, faulting, or tilting, indicating that the rock has not been deformed. Therefore, this photo shows no evidence of deformation by movements of Earth's crust. Option C is the correct answer.
When the Earth's crust undergoes movements, such as tectonic forces, rocks can be deformed. This deformation can take different forms, including folding, faulting, and tilting. Folding occurs when layers of rock bend and fold due to compression. This can result in curved or wavy patterns in the rock layers. Option C is the correct answer.
Examples of folding can be seen in mountain ranges where the Earth's crust has been compressed and folded over time. Faulting happens when rocks break and slide along a fault line. This can create offset layers of rock and visible fractures in the Earth's crust. Faulting can be seen in areas where earthquakes occur, as the movement along the fault line causes the rocks to deform. Tilting occurs when rocks are inclined or tilted from their original horizontal position. This can happen due to tectonic forces or other geological processes. Tilting can be observed in areas where the layers of rock are no longer parallel to the Earth's surface.
