Answer:
It is evident from the distinct magnetite orientation that these two rocks came from the mid ocean ridges.
If the rocks were obtained at the same time, sample A which is the rock with wider band of distinct magnetite orientation (2m) must be from the Easy Pacific Rise and the rock sample B with the shorter band of distinct magnetite orientation (1m) is from the Mid-Atlantic Ridge.
Explanation:
The Mid-Atlantic Ridge is a slow spreading center (leading to broader bands of magnetite orientation). It spreads 2-5 centimeters (0.8-2 inches) every year and forms an ocean trench about the size of the Grand Canyon.
The East Pacific Rise, on the other hand, is a fast spreading center (wide band of distinct magnetite orientation). It spreads about 6-16 centimeters (3-6 inches) every year. There is not an ocean trench at the East Pacific Rise, because the seafloor spreading is too rapid for one to develop!
Hope this helps!!!

True.
Below answers 7 - 8 - 9
Explanation:
7 - With the advent of spacecraft and radar, more precise methods emerged for making a direct measure of the distance between the Earth and the sun. The definition of AU had been "the radius of an unperturbed circular Newtonian orbit about the sun of a particle having infinitesimal mass, moving with a mean motion of 0.01720209895 radians per day (known as the Gaussian constant)" We can say that one astronomical unit (AU) represents the mean distance between the Earth and our sun. An AU is approximately 93 million miles (150 million km)
. It's approximately 8 light-minutes.
8 - One of the main scientific justifications for building Hubble was to measure the size and age of the Universe and test theories about its origin. Images of faint galaxies give 'fossil' clues as to how the Universe looked in the remote past and how it may have evolved with time. The Deep Fields gave astronomers the first really clear look back to the time when galaxies were forming.
The Hubble Ultra Deep Field from 2004 represents the deepest portrait of the visible universe ever achieved by humankind. The Ultra Deep Fields show the furthest away galaxies that can be observed in visible light.
9 - It’s true that the moon goes around Earth every month, but it doesn’t always get in Earth’s shadow. The moon’s path around Earth is tilted compared to Earth’s orbit around the sun. The moon can be behind Earth but still get hit by light from the sun.
Answer: The porous nature of the rock bodies makes them good reservoirs of these fuels.
Explanation:
Oil and natural gases most times occur in porous rocks. These rocks are usually sedimentary rocks like sandstone and limestone. There are three(3) major classes of sedimentary rocks and they are: Clastic sedimentary rock
Carbonate sedimentary rock
Evaporitic sedimentary rock
Clastic rocks are the rocks that are gotten when sediment particles are broken down from formerly existing rocks via processes like rainfall, wind movement, freezing etc, accumulates and cements together.
When the old parent rock is weathered or broken down, the particles and sediments are carried via water from the streams and rivers until they get to another destination where they gather togther and solidify overtime to form sedimentary rocks.
Mud solidifies to become shale which can also be called mudstone.
Sands are cemented via silica or another substance called calcite to form sandstones.
Gravels develop into conglomerates.
Sandstones due to its very inherent porosity found in between the grains become excellent reservoirs for oil and natural gas.
They are connected to a river by some way or another
