Describe a story that you think makes a good human interest story. This might be something that you’ve read/watched or it might be something that you know about from other sources. What makes it a good human interest story?

Answers

Answer:

A story that might be a good human interest story would be the vaccines for corona. Everyone these days are waiting desperately for corona to end. Talking about a vaccine might give them hope, and it would be nice to see how the scientist and doctors truly care for the people. Maybe encourage them to wear the masks until the vaccines come out?

Answer: It could be how to stay safe during this pandemic. Include what to wear ( masks, gloves, face shields, etc.), how far apart you have to stand, only go out when you need to ( grocery shopping), symptoms of this virus and other stuff like that. A lot of people go out and get coronavirus  because they don't know all of this stuff.

Wave Rock, Australia
This concave rock formation is part of the northern side of Hyden Rock located in Hyden Wildlife Park, Western Australia. It is made of granite and estimated at 2.7 billion years old. The wave shape formed over the years by the action of running water weathering the middle faster than the top. The streaks on its face are minerals that were deposited by rainwater runoff.
--------------------------------------------------------------------------------------------------------------------------------
(02.03 MC)

While visiting Wave Rock in Australia, you observe streaks of minerals present on the landform. What natural process most likely caused the streaking?

Select one:
a. Erosion
b. Deposition
c. Oxidation
d. Weathering

Answers

Answer: It would most likely be Erosion i think.

Explanation:Erosion happens when rocks and sediments are picked up and moved to another place by ice, water, wind or gravity. Mechanical weathering physically breaks up rock. ... Over time pieces of rock can split off a rock face and big boulders are broken into smaller rocks and gravel.

Deposition

Explanation: as the weather takes the sediment to the rock it deposits it causing it to from new layers in the rock
