Answer:
Answer is B-No dinosaur fossils are found above the Cretaceous-Paleogene boundary.
Explanation:
The evidence that is most consistent with dinosaurs becoming extinct at the end of the Cretaceous era is that no dinosaur fossils are found above the Cretaceous-Paleogene boundary.
Hence, the correct answer is option b.
The Cretaceous-Paleogene (K-Pg) boundary, also known as the Cretaceous-Tertiary boundary, refers to a geological time boundary marking the transition between the Cretaceous and Paleogene periods, approximately 66 million years ago. It represents a significant event in Earth's history, associated with the mass extinction event that led to the demise of the dinosaurs and many other species.
The boundary is characterized by a thin layer of sediment called the K-Pg boundary clay, which contains high concentrations of the element iridium, suggesting an extraterrestrial impact event, such as a large asteroid or comet impact. This impact is believed to have triggered global environmental changes, including massive volcanic activity, wildfires, and a subsequent nuclear winter-like effect, leading to widespread extinction.

Explain how the intesity of the tropical cyclone increased as it moves from one area to another
Answer:
requirement for the intensification of tropical cyclones is that there must be little change in the wind speed with height above the surface. If the winds increase too much with altitude, the core of the system will no longer be vertically aligned over the warm surface that provides its energy.

The measures of the three angles of a triangle are given by 18x − 7, 12x + 9, and 4x. What is the measure of the largest angle?
Answer:
The greatest angle is [tex]18x-7[/tex]
Explanation:
According to angle sum property of a triangle, sum of all the angles of a triangle is equal to [tex]180[/tex]°.
The given angles of a triangle are [tex]18x-7,12x+9,4x[/tex]
Therefore,
[tex]18x-7+12x+9+4x=180[/tex]°
[tex]34x+2=180[/tex]°
[tex]34x=178[/tex]°
[tex]x=\frac{178}{34}=\frac{89}{17}[/tex]
[tex]18x-7=18(\frac{89}{17})-7=\frac{1602-119}{17}=\frac{1483}{17}[/tex]≈ 87.2°
[tex]12x+9=12(\frac{89}{17})+9=\frac{1068+153}{17}=\frac{1221}{17}[/tex] ≈ 71.8°
[tex]4x=4(\frac{89}{17})=\frac{356}{17}[/tex] ≈ 20.9°
Therefore, greatest angle is [tex]18x-7[/tex]
