Select the statement(s) that accurately illustrate scenarios of weathering. Water flows into cracks in a rock, freezes and expands, pushing against the crack making it wider. Wind gusts carry large amounts of sand across the landscape creating a sandstorm. Plant roots expand cracks in rocks as the plant grows. Sand particles in the blowing wind may act like sandpaper to rub against the rocks and wear off small particles. Oxygen in the air reacts with iron ore in a rock creating streaks of rus

The question would be properly written with options attached for the sake of comprehension:

Select the statement(s) that accurately illustrate scenarios of weathering.

A. Water flows into cracks in a rock, freezes, and expands, pushing against the crack making it wider.

B. Wind gusts carry large amounts of sand across the landscape creating a sandstorm.

C. Plant roots expand cracks in rocks as the plant grows.

D. Sand particles in the blowing wind may act like sandpaper to rub against the rocks and wear off small particles.

E. Oxygen in the air reacts with iron ore in a rock creating streaks of rust

The correct options in the question above are:

Options A, C, D, and E.

Explanation:

First, Weathering is the actions that lead to the gradual but continuous breakdown of rocks and minerals into soils. There are two main kinds of weathering: mechanical  weathering and chemical weathering.

From the question above, options A, C, and D are all examples of mechanical weathering where rocks are broken down physically into smaller pieces.

Option B would have also been correct but didn't mention that the sandstorm brushed against the rock or collided with it.

While option E is an example of chemical weathering because of the chemical reaction between the oxygen in the air and the iron ore in rock. This results in the breakdown of minerals that are rich in iron forming new compounds creating rust.

a few examples of ethical concerns involving genetically engineering of humans include

-privacy of genetically tested people

- potential side effects

-long term effects
