I'm doing this one right now and I think it's d but I dont know for sure
An earthquake is what happens when two blocks of the earth suddenly slip past one another. The surface where they slip is called the fault or fault plane.
<h3>
Convergent boundaries</h3>
Convergent boundaries refers to where crust is destroyed as one plate dives under another. Transform boundaries, on the other hand, is where crust is neither produced nor destroyed as the plates slide horizontally past each other.
Therefore the correct answer is convergent boundaries.

Complete Question
Select the statements about the K-T boundary that are true. Select all that apply. Select all that apply. a. The K-T boundary dates to 65 million years ago (when the dinosaurs disappeared). b. The K-T boundary separates rock layers of the Cretaceous period from those of the Tertiary period. c. The K-T boundary is a thin layer of clay found only in Gubbio, Italy. d. The K-T boundary in Zumaia, Spain is sharp--representing an abrupt change in the Marine ecosystem.
Answer:
a. The K-T boundary dates to 65 million years ago (when the dinosaurs disappeared).
b. The K-T boundary separates rock layers of the Cretaceous period from those of the Tertiary period.
d. The K-T boundary in Zumaia, Spain is sharp--representing an abrupt change in the marine ecosystem.
Explanation:
In the K-T boundary,the K represents the Cretaceous period while T represents the Tertiary period.
Geologists have said the K-T period occured 65 millon years ago and the evidence was the extinction of Dinosaurs and other species taking their place.
Some researchers have claimed that it was an asteroid that hit the Earth 65 millon years ago resulting in the wiping out of dinosaurs.
The K-T boundary can be defined as the time of separation or distinction between the Cretaceous period and the Tertiary period.
The K-T boundary separated the rock layers of the Cretaceous period from the rock layers of the Tertiary period.
Answer:
Aquaculture has been considered as an option to cope with the world food demand. However, criticisms have arisen around aquaculture, most of them related to the destruction of ecosystems such as mangrove forest to construct aquaculture farms, as well as the environmental impacts of the effluents on the receiving ecosystems. The inherent benefits of aquaculture such as massive food production and economical profits have led the scientific community to seek for diverse strategies to minimize the negative impacts, rather than just prohibiting the activity. Aquaculture is a possible panacea, but at present is also responsible for diverse problems related with the environmental health; however the new strategies proposed during the last decade have proven that it is possible to achieve a sustainable aquaculture, but such strategies should be supported and proclaimed by the different federal environmental agencies from all countries. Additionally there is an urgent need to improve legislation and regulation for aquaculture. Only under such scenario, aquaculture will be a sustainable practice.
