Directions: Each of the underlined word groups contains one or more errors. As you locate and identify each error, write its item number on the appropriate line below. Then, edit the underlined word groups to correct the errors.

Every time you step outside, you are under attack.
You may not know what is hitting you, but the attack is truly happening.
Invisible storms of sky dust rain down on you all the time.
It does not matter if the sun is shining and the sky is bright blue.
The dust is still there.
Sky dust consists of bug parts, specks of hair, pollen, and even tiny chunks of comets.
According to experts, 6 million pounds of space dust settle on the earth’s surface every year.
You will never notice it; however, scientists are collecting it to learn more about weather patterns and pollution.
Using sophisticated equipment like high-tech planes and sterile filters to collect dust samples.
Dan Murray, a geologist at the University of Rhode Island, has begun a new project that invites students and teachers to help collect samples of cosmic dust.
Murray says that collecting the dust particles is quite simple.
It starts with a researcher setting up a small, inflatable swimming pool.
Next, the investigator leaves the pool out in the open for 48 hours.
Finally, the researcher uses a special type of tape to pick up whatever has settled over time.
The tape is put into a beaker of water to dissolve, and a microscope is used to analyze what comes off the tape.
The information found there will help scientists predict insect seasons, measure meteor showers, or even catch signs of global warming.

Answer 1

Cosmic dust consists of various elements and particles, including bug parts, hair, pollen, and cometary fragments. Scientists collect cosmic dust to understand weather patterns and pollution. Students and teachers can participate in collecting cosmic dust by using a simple method.

Step-by-step explanation:

Every time you step outside, you are exposed to cosmic dust, which consists of bug parts, specks of hair, pollen, and tiny chunks of comets. According to experts, 6 million pounds of space dust settle on the earth's surface every year. While you may not notice it, scientists are collecting it to learn more about weather patterns and pollution. One project invites students and teachers to help collect samples of cosmic dust using a simple method.

To collect cosmic dust, a researcher sets up an inflatable swimming pool outdoors for 48 hours. The pool captures whatever has settled over time. A special type of tape is used to pick up the dust particles, which are then dissolved in water and analyzed under a microscope. The information gathered from these samples can help scientists predict insect seasons, measure meteor showers, and even detect signs of global warming.
