Explanation: it shows the earth all in one. Makes it easier to study
Answer:
These two plates will form mountains.
Explanation:
This is an example of convergent boundaries. Convergent Boundaries are formed when two plates move towards each other. Converge means to come together from different directions and meet at one place
In the case of you question, India and Asia are an example of a Convergent Boundary. According to the theory of Continental Drift - India crashed into India. The two land masses buckled and folded - forming the Himalayas!
Answer:
Carbon dioxide and water vapour concentrations will lead to change in temperatures.
Explanation:
- Most of the common volcanic gases include carbon dioxide, sulphur dioxide and hydrogen sulphide along with small quantities of volatile compound and elements present such as hydrogen, helium and chloride etc.
- The carbon dioxide and water vapour alter the temperature During the experiment the concentration of carbon dioxide goes up and the temperature goes down. Thus volcanic eruption often leads to global cooling.
Answer:
potassium-argon dating
Explanation:
Potassium-argon (K-Ar) dating technique is the most appropriate dating method for establishing the age of a volcanic ash. It is most applicable for dating minerals and rocks more than 100,000 years old. It is based on measuring the product of the radioactive decay of an isotope of potassium (k) into argon (Ar). Since potassium is a common element found in many volcanic ash layer, the time since re-crystallization is calculated by measuring the ratio of the amount of argon 40 (Ar-40) accumulated to the amount of potassium 40 (K-40) remaining in these volcanic ashes.
