Answer:
Explanation:
1.The powerful surf and the salt of the erratic and moody Southern Ocean started to erode the rugged limestone cliffs along Victoria's Coastline.
2.Animals that burrow underground, such as moles, gophers or even ants, can also cause physical weathering by loosening and breaking apart rocks. Dens and tunnels are signs of this type of weathering. Other animals dig and trample rock on the Earth's surface, causing rock to slowly crumble apart.
3.When the smaller rock pieces (now pebbles, sand or soil) are moved by these natural forces, it is called erosion. So, if a rock is changed or broken but stays where it is, it is called weathering. If the pieces of weathered rock are moved away, it is called erosion.
I would say the results of the experiment but not the hypothesis, if we're saying possible corrections to the hypothesis count as something outside of it
A) Polaris is much farther from Earth than the Sun -is the reason why Polaris although about 46 times larger than the Sun, the Sun appears brighter than Polaris from Earth.
Explanation:
Astronomers define the brightness of a star based on its apparent magnitude and absolute magnitude. The apparent magnitude tells about how bright does a star looks from the Earth. The absolute magnitude of star is its brightness or magnitude at a standard distance of 10 parsecs or 32.6 light-years.
Accordingly,
The apparent magnitude of Sun is 26.74; while that of Polaris is 2.02
The absolute magnitude of Sun is 4.63; while that of Polaris is 3.6
The Sun is at a distance of 0.000015649 light years from the Earth; while the Polaris is 434 light years from the Earth. A star appears brighter from the Earth due to the closeness of the star to the Earth.
All these factors make the Sun appear brighter than the Polaris
