Answers

Answer:

Explanation:

1. The Moon continues to spin away from the Earth, at the rate of 3.78cm (1.48in) per year, at about the same speed at which our fingernails grow. ... The migration of the Moon away from the Earth is mainly due to the action of the Earth's tides

2. Acid rain is caused by a chemical reaction that begins when compounds like sulfur dioxide and nitrogen oxides are released into the air. ... In addition, the exhaust from cars, trucks, and buses releases nitrogen oxides and sulfur dioxide into the air. These pollutants cause acid rain.

3. Formation. When the solar system settled into its current layout about 4.5 billion years ago, Earth formed when gravity pulled swirling gas and dust in to become the third planet from the Sun. Like its fellow terrestrial planets, Earth has a central core, a rocky mantle, and a solid crust.

4. The chances of an Ice age are 1.25%

5. I have no answer for that

6. God created earth. It says it in the bible (Genisus.)

7. Cause the sun has not died or bursted...yet.

8. Freezing does not kill germs and bacteria. Instead, it essentially puts them into hibernation. They are inactive while the food is frozen and will “wake up” as soon as the food thaws. And as the food thaws, so will the moisture, which means the bacteria will have the moisture it needs to survive.

9. Cause the core of the earth is trillions of degrees.

10. There would be mass flooding from sea levels rising, severe weather changes, deadly chemical releases, and mass greenhouse gasses that would leak into the atmosphere. Scientists say we need to stop the planet from rising in temperature by just 1° Celsius, or this could happen sooner than we think.

11. Differences in temperature, pressure, and structural formations in the mantle and crust cause magma to form in different ways. ... The rock then cools into new crust. Decompression melting also occurs at mantle plumes, columns of hot rock that rise from Earth's high-pressure core to its lower-pressure crust.

HELP!!! A student observes that she's always sleepy shortly after eating lunch, and she wants to be able to pay better attention in her mid-afternoon class. She tried doing 10 jumping jacks just before the class, but still felt sleepy around the middle of the class. The next day, she tried sipping water throughout the class and found that she could pay attention until the end of the class. The student now brings a water bottle to class.
*Identify how this student applied the scientific method to solve her problem.*

Answers

Answer:

In this scenario, the student applied the scientific method to solve her problem in that she first established there was a problem, then formulated some hypotheses about why there was a problem, and then did experiments to test the hypotheses.

Explanation:

Hope This Helps!

It's essential for students (and everyone) to stay adequately hydrated throughout the day to maintain overall well-being and cognitive function. Bringing a water bottle to class is a practical and healthy habit that can help the student remain focused and attentive during the class and other daily activities.

Hydration and Cognitive Function: Proper hydration is essential for optimal cognitive function. When the body is dehydrated, it can lead to feelings of fatigue and decreased mental alertness. Drinking water helps maintain the balance of body fluids, and the brain relies on adequate hydration to function at its best.

Blood Flow and Oxygenation: Staying hydrated supports proper blood circulation, including to the brain. Sipping water can help ensure that oxygen and nutrients are efficiently delivered to brain cells, enhancing cognitive performance.

Thirst as a Sign of Dehydration: Feeling sleepy or fatigued after eating lunch could be a sign of dehydration, especially if the lunch is salty or doesn't contain enough fluids. By sipping water during the mid-afternoon class, the student is addressing any potential dehydration and its associated effects on attention and alertness.
