An environmental change is occurring due to continents shifting and moving to different parts of the earth’s surface is a long term change due to tectonic plates movements. if this happends for the continously then there will be different sesonal changes .
Answer: Chemical weathering decomposes or decays rocks and minerals. An example of this is water and limestone. Organic weathering happens when plant break up rocks. One the rock has been weakened and broken up it is ready for Erosion. This happens when rocks are picked up and move usually by water. Mechanical weathering breaks up rocks, this usually happens when water gets into cracks, freezes and expands the rock
Explanation:
The Precambrian eon is separated from the Phanerozoic eon in the fossil record because of the sudden appearance of organisms.
Explanation:
Precambrian eon is the initial existence on earth that can be predicted by the study of rocks and remaining of fossils. It has been seen as the existence of skeleton in this era, before this era no such things has been observed, even the development of sexual reproduction.
The Phanerozoic era comes after the Precambrian era, more advanced kinds of fossils of animals had been observed in this era. Phanerozoic era period of life on earth. Large organisms sudden appearance are seen in the Phanerozoic era i.e. First dinosaurs, mammals, fishes, angiosperms,first vertebrates etc.
The force of gravity affects all objects on Earth by pulling them towards the centre. The Earth is close to spherical in shape as this is the geometry gravity prefers. Without gravity, objects would be floating in space. The atmosphere would not exist as the air particles would have no force pulling them towards the planet. Gravity means when you throw something up, most of the time it will come down. It is a force, which causes objects to accelerate when they fall.
Answer:
<em>The correct options are A) They move to another environment.</em>
<em>B) They risk dying out.</em>
Explanation:
According to natural selection, only those organisms are able to live and survive in an environment which can adapt to the changes in an environment. Such organisms reproduce and pass on their characteristics to their offsprings.
Organisms which are not able to adapt to changes in an environment either migrate to other places or die as they are not able to survive by the changes being made.
