Answer:
The geological process and interactions like earthquakes, volcanic eruption, cyclone etc, are responsible for the changes because these are very fast and sudden.
Explanation:
It is 4.5 billion years that Earth has been formed and there have been changes since then. Earthquakes, volcanic eruption, cyclone etc, are some of the geological process and interactions are the reasons for change in earth's surface. An earthquake usually split or divide the surface into many pieces in a very few seconds. While lava erupted from a volcano makes the land fertile by spreading around within minutes whereas a day of rainfall can lead to a flood in the neighborhoods and results in many losses.
Hydrolyte geodes have been found in <u>Brazil</u>.
<u>Explanation:</u>
Hydrolyte geodes which are agate, amethyst and quartz have been found in South American continent in country Brazil. These are geological secondary formation in which the masses of matter of minerals which might also include crystals are not seen.
In physical appearance, they are hollow, and are roughly formed circular rocks and are formed within sedimentary and volcanic rocks and they are subjected to to hydrolysis.
Desertification occurs<span> due to a decrease in vegetation. This can </span>happen<span> naturally due to a drought or can be caused by human activities. The lack of plants can cause changes to the land. Plants help shade the soil, so when plants are removed, the soil will be exposed to the sun and will dry out more quickly. So, I would say C. An area of forest is clear cut.

<u>ANSWER:</u>
The central area of the Inter mountain Region where water in streams is 'trapped and evaporates' is called the great basin.
<u>EXPLANATION:</u>
- The rivers in the 'great basin' will not join into oceans or rivers.
- The streams and rivers in the 'great basin' form a pool or lake in the valley area and evaporates there.
- Some pools are sucked into the grounds. The water in the 'great basin desert' is too little to be pushed from the mountain region into the oceans or any big rivers.
