Answers

Answer 1

Answer:

The correct option is C) continental crust does not undergo subduction while oceanic crust.

Explanation:

The oceanic crust comprises of basalt while continental crust comprises of granite. The oceanic crust is much thinner than continental crust. While density of oceanic crust is more than continental crust. This is the reason the continental crust are floating while oceanic crust are not that buoyancy. Geologically, the continental crust is older than oceanic crust.

The crust is classified into continental crust and oceanic crust. The outer layer of the earth is crust which is floating on the molten mantle.

Answer 2

Answer: The oceanic plate is denser, so it undergoes subduction.

This statue of Leshan Giant Buddha in Sichuan, China, is carved directly into the mountainside. The color and texture of the statue are constantly changing due to the pollutants from vehicles and industries nearby. What are the two main causes of the changes to the statute?

Answers

The correct answer is - B. rainfall and chemical reaction.

The Great Buddha statue is under constant change and it is slowly but surely weathering bit by bit. The two biggest reasons for this are:

- The rainfall; the water from the rainfall is one of the biggest causes of weathering of the rocks, the water is known to decompose the rocks over time and the Great Buddha statue which is on an open space is not an exception of its influence.

- The chemical reactions; China has a huge problem with pollution. There's lots of pollutants in the air that are causing serious damage to most things, including the Great Buddha statue, and they contribute to quicker decomposing with their corrosive power and change in colour than anything else.

The correct answer to this question is letter "B.rainfall and chemical reaction."

Looking at the choices,
A. wind and rainfall, C.rainfall and gravity,
D.gravity and wind are natural phenomenon and we are not sure what's in the wind and rainfall.

B.rainfall and chemical reaction, E.wind and chemical reaction shows the reaction to the statue. It's more likely to be rainfall than wind.

What can fossils reveal about earth past?

Answers

Fossils show how organisms have changed over time.
Fossils also show us how Earth itself has changed. e.g. Similar fossils have been found on both sides of the Atlantic Ocean. Many of the organisms that left these fossils could not have crossed an ocean. The finding of these fossils in distant places supports the theory of CONTINENTAL DRIFT. This is the theory that the continents have been slowly drifting apart for millions of years.
