Answer:
1 and 5
Explanation:
The image of the different rocks are attached. From the image attached, it can be seen that rock 1 and rock 5 have a fine grained texture.
Fine grained rocks are formed from volcanic eruptions. During these eruptions, the molten magma is cooled fast at or close to the earth surface thereby forming rocks with a fine grained texture. The rock has fine grains because the crystals are small because of the fast cooling of the molten magma. Slow cooling causes the crystals to be large thereby forming coarse rocks such as rocks 2, 3 and 4.
Good Morning!
There were several transformations in the transition from the 19th to the 20th centuries. These included advances in medicine, architecture and basic sanitation, which ensured that quality of life not only improved but was maintained. All this adds up to the rise of the fastest and most efficient means of transport, which has allowed longer distances to be covered in less time.

Who did the Russian choose to send to space?
The Soviet Union decided to send astronaut Yuri Gagarin. He was the first human into space. His capsule was named "Vostok," which completed its orbit on April 12, 1961.
Another response to the launching of Sputnik by the Soviet Union in 1957 was that the US federal government began spending billions of dollars to improve American science education.
The space program had to be sped up because, in those years of the Cold War, it was inadmissible for the United States to behind the Soviet Union in the space race. The United States federal government also invested a lot in education and space research.
