請問23題為甚麼不是花剛岩 不是陸跟陸聚合嗎 要怎麼區分ㄚ

-do 三、混合題(每題4分,共12分) ◎火山和斷層活動都會引發地震,而臺北附近兩者兼具。臺灣北部最大的火山就是大屯火山和七星 山,科學家在此處設立小型地震觀測網進行微震觀測。由觀測資料分析,火山地震的基本特徵是 震源淺、規模不大且常為群震發生,震央會集中於火山及其附近。在大屯火山觀測到的地震可分 成四種: (1)一般構造地震:與斷層地震同,有P波、S波,震源深度不到5公里,是密集的微震 (2) 單頻率的「水滴型震波」:無法辨別P波和S波,這些地震訊號的產生原因,最可能是由岩層 裂縫中液態或氣態物質共振所引起 (3)多頻率的「螺絲釘型震波」:時間長達數十秒,可能代表該火山活躍性很強 (4) 高頻火山地震訊號:持續十多分鐘且有強烈和連續性的爆發,通常出現在岩漿庫的附近 一般地震波 水滴狀地震波 螺絲釘狀地震波 ith huk IN (a) 50510 振幅 一般地震波 2 4 6 時間(秒) 一般 地震波頻譜 (b) 2 振 0 水滴狀 幅 地震波 -28 螺絲釘狀地震波 0 2 4 6 8 10 0 10 20 30 40 時間(秒) 時間(秒) 10F 158 8. 螺絲釘狀 水滴狀 108 地震波頻譜 地震波頻譜 幅 5 2 3 4 頻率(Hz) 2 468 振幅 振幅 10 20 30 頻率(Hz) 頻率(Hz) 10 12 資料參考:「大屯火山觀測站」網頁: http://tec.earth.sinica.edu.tw/TVO/free.php?link=obrwork/microseismic 2 √ (2) 由上文所述可知,在火山活動區域,也會有斷層活動,請問火山造成的地震與一般斷層的地震有 何差異? (A)一般地震波搖晃時間比較長 (C)火山只有在噴發前才會有地震 (B)火山地震可能會有無法辨別P波和S波的地震 (D)火山地震通常規模大且震源深 (E)一般地震比火山地震更常會有群震 智口 -4. 振幅 22. 除了看震波,地震也能「聽聲音」,關鍵在於地震發出的頻率,在大屯火山觀測到的地震,發出 的頻率各有不同,請問下列敘述何者錯誤? (A)一般地震有多種頻率,每種強弱不一 (C)螺絲釘狀的地震波頻率有多種 (B)水滴型地震波的頻率是單頻特別強 (D)持續時間最長的是高頻地震訊號 (E)這些地震頻率人類耳朵(20~2萬Hz)都能聽到 智 〔 臺灣北部會有火山活動的主要原因,是此區的板塊運動屬於何種類型的邊界?若大屯火山噴發, 岩漿冷卻後主要形成何種岩石? 图 聚合型,花安山岩

想請問下方兩題, 16.主要是不知道as在那裡的作用(因為as看很久還是錯了),以及為什麼要使用被動 17.是覺得四個都可以🥲 非常感謝!!

13. (A) if 14. (A) helps 15. (A) Unfortunately 第16.至20.題為題組 The five-pointed star drawn with five lines is known today as the pentagram. It is an ancient symbol which has held different meanings. Today, we can see the pentagram 16. as jewelry or designs on clothing. The Sumerians were the first to use the five-pointed star polygon. They wrote about the symbol in records 17. 3000 B.C. In the context of that civilization, the pentagram was a character in a writing system. The Babylonians, a culture with close historical links to Sumer, used the pentagram 18. the planets. Its five points indicated five planets - Mercury, Venus, Mars, Jupiter, and Saturn. In ancient China, the pentagram corresponded to Wu Xing, the five elements that make up the world: metal, wood, fire, earth, and water. In European folklore, it was said to come with magical properties. The 19. of the star affected its significance. With one point facing upward, the pentagram represented "white" magic (good). 20. with two points facing upward, the same symbol stood for "black" magic (evil). Nowadays the symbolism of the pentagram is still commonly used, but it is good to know more of its history than just a fashion statement. 16. (A) wearing (B) worn 17.
