How are ice and water involved in mechanical weathering

Answers

Answer 1

Answer: Mechanical Weathering is weathering done physically.
Water can seep into rocks' cracks and overtime freeze and pry the rock to open.
When water freezes, it, obviously, turns into ice.

True

Explanation:

Which of the following statements about stellar parallax is true? a. We observe all stars to exhibit at least a slight amount of parallax.
b. Stellar parallax was first observed by ancient Greek astronomers.
c. The amount of parallax we see depends on how fast a star is moving relative to us.
d. The closer a star is to us, the more parallax it exhibits.
e. It takes at least 10 years of observation to measure a star's parallax.

Answers

Answer:

c. The amount of parallax we see depends on how fast a star is moving relative to us.

Explanation:

The stellar parallax is obtained by a mathematical calculation, is a geometrical measure among the Earth and another star. For example, by now, it is known the distance from the Earth to the sun, so, is like this star can be observed by two eyes. The Earth and the Sun. If we joined the two lines from the Earth and the Sun too the star, it will form a triangle. With some calculation and the angle formed, it can be determined the distance to the star.

Hope it was useful.

Final answer:

The true statement is: the closer a star is to us, the more parallax it exhibits. Stellar parallax, the apparent shift of a star's position due to Earth's orbit, is used to measure star distances. The other options provided are not entirely accurate.

Explanation:

The correct statement about stellar parallax among the options given is d. The closer a star is to us, the more parallax it exhibits. Stellar parallax is the apparent shift of the position of a nearby star against the background of distant stars due to the orbit of Earth around the Sun. This method is used to measure the distances of nearby stars. The amount of parallax observed for a star decreases as the distance to the star increases. Thus, a closer star will have a larger apparent shift, or parallax, than a star farther away.

Options a, b, c, and e are not entirely correct:
a. Not all stars exhibit a noticeable parallax because some are too distant.
b. The concept of parallax was certainly known to ancient Greek astronomers, but precise measurements were not possible until modern times with more sophisticated technology.
c. The speed of a star relative to us has no effect on its parallax - it is entirely due to Earth's motion.
e. Parallax can be measured with less than a year of observation - what is needed is to observe the star from positions six months apart in Earth's orbit.

An observer in canada sees a third quarter moon on a particular day. What will an observer in australia see on the same day?

Answers

Answer:

Australian observers will see a first quarter of moon on the same day.

Explanation:

This difference arises due to the fact the moon tends to be seen in complete reversal i.e upside downwards. The moon is in the same plane as that of the earth's equator.

Moon tends to be flipped in the southern hemisphere and opposite in the northern hemisphere.

Clockwise In the northern hemisphere, the moon in the southeast, the moon is from left to right. In the southern hemisphere, it's anticlockwise, east on right and west on left.
Thus the face of the moon will be right to left. Also, there is a time gap between both the northern and southern countries.
