Answer: 1) Angular separation equals 0.0000031 degrees
2) Angular separation in arc -seconds equals 0.011156"
Explanation:
For 2 stars separated by a distance 'S' and at a distance 'D' from the earth the angular separation in radians is given
Applying values we get
Now we know that 'π' radians equals 180 degrees thus the above value in degrees shall be equal to
2)
The angular separation in arc- seconds is given by
The correct answer is - 2. Earth's climates have changed and are likely to change in the future.
From what is known for the geologic past of the Earth, our planet's climate has been changing numerous times. The climate on the planet has varied from being predominantly wet tropical climate, to having ice ages, having multiple different climate types at the same time... The reasons for the changes in the Earth's climate are numerous, with the Sun's radiation, tectonic movements and activities, volcanic activity, outside influences like asteroid and meteorite collisions, the vegetation, and all of them have managed to create a very colorful climate history of the planet. This trend of climate change should continue in the future as well, as all of the aforementioned factors are still influencing the climate and on top of that the humans have become a factor in the climate change too.

Answer:
A) The ice lobes advanced and stopped many times, eroding the land to create a trough and then filled it with draining water from the ice sheet that was feeding them.
Explanation:
- The creation of the Minnesota rover started when the bottom was an oversized valley having its roots in the ice ages when the glacier repeatedly moved 2 to 10,000 million years ago. For about 120-150,000 years ago the ice sheets formed by the lobes of ice in Minnesota and it was covered by moraine and glacial deposits.
