Answer:
Positive feedback
Explanation:
Positive feedback climate is usually defined as the process where there occur changes in the region where the lighter colored surfaces such as the region of glaciers, ice caps are replaced by the dark-colored surfaces, and this results in the decreasing of the albedo (light-reflecting property) and also increase in earth's surface temperature. This type of feedback is also known as the ice-albedo feedback.
High rate of heating results in the decreasing amount of glaciers and ice-caps, thereby leading to the global warming effect.
Thus, the above-given condition is an example of positive feedback.
Answer:
knowledge
Explanation:
people want to have the big brain lol
nah but seriously, having an education and knowledge can get you a good paying job.
The evidence provided by the fossils means that Trilobites became extinct 252 million years ago and lived on Earth more than 521 million years ago.
Basically, a fossil is a remains which gives geologist information about the organism which lived in the past because when those organism dies, they decay and remain on or in the earth surface
Since the trilobite fossils are found in rock that are 521 million years and 252 million years old, then, it means that:
- Trilobites became extinct 252 million years ago therefore, no other remains keep existing on rocks earlier.
- Trilobites lived on Earth more than 521 million years ago
Therefore, the Option A and D is correct.

Answer:The Earth's lithosphere is relatively hard rigid-like whereas, the asthenosphere is relatively hot and plastic-like
Explanation: The surface of the lithosphere has the rocks which can bent but does not flow , that is having rigid nature whereas the asthenosphere has comparatively have a flow in nature and are considered as plastic-natured .The lithosphere is segmented into rigid plates that are present on top of the flowing asthenosphere.
It is stated that the hard rocks don not flow while the flow can be seen in the plastic -like rocks.
Since the continental crust density is the same, when both of them collide, there will gradually occur a huge mountain chain cause of the uplifting of the collision point and it's surrounding area, today known as the Himalayan mountains, the highest in the world (note: if measured from sea level) with it's peak Mount Everest (Sagarmatha) at 8848 m above sea level (it is estimated that it grows 8 cm per year).
