Why do limestone rocks dissolve in rainwater?

Answers

Answer 1

Rainwater contains carbon dioxide from the air that has dissolved, making it slightly acidic. Limestone can be broken down by this mild "carbonic acid" as it seeps into crevices and cracks.

The main constituents of limestone, a sedimentary rock, are calcium carbonate and calcium and magnesium double carbonates. In its composition, small fossils, shell fragments, and other fossilized debris are frequently discovered.

Because extremely weak carbonic acid may dissolve the mineral grains of limestone in nature, limestone is special. Water from rain and carbon dioxide from the atmosphere and soil combine to make weak acids. Large areas of the Earth's surface are exposed to limestone, and because limestone is only marginally soluble in precipitation, these exposures frequently erode to form karst landscapes. In limestone bedrock, the majority of cave systems are found.

Here is a step-by-step guide that may be useful if you are called upon to give an impromptu speech in public.

Take a moment to collect your thoughts and plan the main point you want to make.

Thank the person for inviting you to speak.

Deliver your message, making your main point as briefly as you can while still covering it adequately and at a pace your listeners can follow.

Thank the person again for the opportunity to speak.

Stop talking.

How we deliver a speech is just as important, if not more so, than the basic message we are trying to convey to an audience. But if you have worked hard on preparing the verbal part of your speech, you may feel that delivery is just an “extra” that should not require much time or effort. After all, your speech is carefully planned, researched, and polished. It is committed safely to paper and hard drive. It’s a carefully constructed, logically crafted, ethical message. The words alone should engage your audience’s attention and interest—right?

After all the work of building such a message, you might wish that you could simply read it to the audience. However, this is the case in only a few kinds of circumstances: when the message is highly technical, complex, and extremely important (as in a new medical discovery); when international protocols and etiquette are crucially important and the world is listening; or when the speaker is representing a high-ranking person, such as a president or a king, who is unable to be present. For the purposes of your public speaking class, you will not be encouraged to read your speech. Instead, you will be asked to give an extemporaneous presentation. We will examine what that means.

The nonverbal part of your speech is a presentation of yourself as well as your message. Through the use of eye contact, vocal expression, body posture, gestures, and facial display, you enhance your message and invite your audience to give their serious attention to it, and to you. Your credibility, your sincerity, and your knowledge of your speech become apparent through your nonverbal behaviors.

The interplay between the verbal and nonverbal components of your speech can either bring the message vividly to life or confuse or bore the audience. Therefore, it is best that you neither overdramatize your speech delivery behaviors nor downplay them. This is a balance achieved through rehearsal, trial and error, and experience.

In this chapter, we are going to examine effective strategies for delivering a speech. To help you enhance your delivery, we will begin by exploring the four basic methods of speech delivery. Second, we will discuss how to prepare your delivery for different environments. Third, we will talk about how to effectively use notes to enhance your delivery. Finally, we will examine characteristics of good delivery and give some strategies for practicing effectively for the day when you will deliver your speech.

Impromptu speaking is the presentation of a short message without advance preparation. Impromptu speeches often occur when someone is asked to “say a few words” or give a toast on a special occasion. You have probably done impromptu speaking many times in informal, conversational settings. Self-introductions in group settings are examples of impromptu speaking: “Hi, my name is Steve, and I’m a volunteer with the Homes for the Brave program.” Another example of impromptu speaking occurs when you answer a question such as, “What did you think of the documentary?”

The advantage of this kind of speaking is that it’s spontaneous and responsive in an animated group context. The disadvantage is that the speaker is given little or no time to contemplate the central theme of his or her message. As a result, the message may be disorganized and difficult for listeners to follow

How does this excerpt help readers make a personal connection to the story? by offering details about Wash's daily routines by giving the measurements of Wash's tub by providing information about the high cost of hot water by offering suggestions for maintaining cleanliness

Answers

This question is missing the excerpt. I've found the complete question online. It is the following:

Read this excerpt from We've Got a Job: The 1963 Children's March.

To take a bath, they first had to lug water to their room from the only sink in the house, near the bathroom. "We had a Number Ten tub," Wash explained, describing the high-sided tin contraption. "We boiled water, poured [it] into the tub, and then put cold water in the tub. And that's what we took a bath in, because there was no such thing as hot water in the house."

How does this excerpt help readers make a personal connection to the story?

A. by offering details about Wash's daily routines

B. by giving the measurements of Wash's tub

C. by providing information about the high cost of hot water

D. by offering suggestions for maintaining cleanliness

Answer:

This excerpt helps readers make a personal connection to the story:

A. by offering details about Wash's daily routines.

Explanation:

A personal connection to a story happens when readers are reminded of their own personal experiences when reading that story. The excerpt we are analyzing here offers that chance to readers by describing Wash's daily routine. It is likely that several readers have gone through similar experiences in life, for several reasons. Even if the experiences were not the same, reading about someone's simple daily struggles like this helps readers feel that that character - fictional or not -  is an ordinary person, just like they are, and with whom they can relate. Thus, connection is created.
