Answer:
A
Explanation:
The climate of a region is determined through the observation of weather patterns over a long time- usually at least 15 years-  in a region. Studying climate change would therefore also take very long time as meteorologists attempt to perceive changes in these weather patterns. In this case 30 years can be enough to notice a significant increase in rainfall patterns which can be classified as climate change. 
 
        
             
        
        
        
<h3><u>Answer;</u></h3>
A. counterclockwise toward the center
<h3><u>Explanation;</u></h3>
- <em><u>In the Northern Hemisphere, winds associated with a low-pressure system blow in a counterclockwise direction towards the center, while those that are associated with a high-pressure system blow in clockwise direction outwards from the center.</u></em>
- In the Southern Hemisphere on the other hand, winds that are associated with a low-pressure system blow clockwise towards the center.
- <em><u>The rotation of the earth creates a force called the Coriolis force, which gives the wind that is within high pressure systems a clockwise circulation in the northern hemispheres and a counterclockwise circulation in the southern hemisphere.</u></em>

When Amanda poured some of the liquid into a test tube, the water curved upwards because of adhesion.
Water has many interesting properties. One of its many properties is its affinity for adhesion. Adhesion is simply what occurs when a molecule of one kind is attracted to a different kind of molecule. 
In the case of Amanda, the water will have curved upwards as an example of the adhesion properties of the water, in which its molecules were attracted towards the edges of the test tube.
