Answer:
1.lacustrine clays and silts
2.The likely geologic origin will be water disposition
3. strength and compressibility
Explanation:
What kinds of soils would you expect to find beneath the city
Answer->lacustrine clays and silts
what would be their likely geologic origin
-The likely geologic origin will be water disposition.
disposition can be defined as a situation whereby a material transported by water is deposited.
What would be the typical engineering characteristics of these soils?
The engineering characteristics will be found in its strength and compressibility. It has the capacity to withstand external force.
They are grainlike with dimension of about 0.06mm, Sedimentary in property and can be used for engineering activities
Extinct animals can be the evidence of pre-existing life , such as dinosaurs
Answer:
Option: a. 200 million years ago
Explanation:
Million years ago, Earth had one supercontinent called Pangaea and surrounded by an ocean (Panthalassa). Alfred Wegener proposed the concept of one big continent after putting together different records of confirmation. He was able to give his theory by examining fossils of plants, trees, animals, and reptiles that found in different continents. About 200 million years ago, the supercontinent began to split up into two parts; Gondwana from Laurasia. Today's countries, including Africa, Antarctica, India, South America, and Australia are part of Gondwana, where Europe and North America from Laurasia.
First, boiling is the change of state from a liquid to a gas. Second, boiling of a pure substance occurs at a particular constant temperature called boiling point.
First, the change of state from a gas to a liquid is called condensation. Second, a pure substance condenses at a temperature equal to its boiling point.
Hope this helps you!
