Explanation:
minerals- is a naturally occuring inorganic solid with a chemical composition and crystalline structure.
rocks- is aggregate of more minerals some rocks are predominantly composed minerals.
I believe the correct answer from the choices listed above is the second option. In the summer, temperatures exceed 100 f, whether it's a cloudy day or clear day. The seasonal weather condition expressed here is the summer. It <span>is the hottest of the four temperate seasons, falling between spring and autumn.</span>
Answer:
1. giant impact forms moon
2. end of heavy bombardment
3. early life (based on fossil evidence))
4. oxygen buildup in atmosphere
5. earliest mammals
6. dinosaurs go extinct
7. earliest humans
Explanation:
The Earth has a very interesting past, with lot of changes and turnarounds in it. If we sum it up quickly, we can say that soon after the Earth formed and collided with another large space object, part of the Earth was torn away, which eventually formed the moon. The Earth was constantly bombarded by meteorites and asteroids, but that came to an end as the atmosphere was becoming denser and denser. The first life started to develop in the oceans in the form of cyanobacteria, which used photosynthesis, and were constantly releasing oxygen, building it up int he atmosphere. The oxygen changed the living conditions, enabling the life to thrive and diversify. The dinosaurs and mammals eventually came on the scene, with the dinosaurs coming first by around 20 million years, giving them the edge to become the dominant life form. The mammals lived in the shadows until the dinosaurs existed, but their reign ended with a large meteorite collision. This prompted the quick evolution and diversification of the mammals, quickly becoming the dominant life form, and just few million years ago they gave rise to the earliest human ancestors, the hominids.
Answer:
Scientists believe that plate tectonics is an example of an internal force that changes the Earth’s crust.
Plate tectonics is a theory that describes the motion of seven large plates, and many other smaller plates of the Earth's lithosphere. When they collide they can make mountains or we can feel their motion as earthquakes. Their motion is responsible for the continental shift and it made our continents look the way they look today.
<span>Weathering,
by definition, is the physical integration and chemical decomposition of earth
materials at or near the earth’s surface. Erosion, by definition, is the
gradual destruction of something by natural forces (e.g. water, wind, ice).
Therefore, the characteristic of both weathering and erosion is that it occurs
naturally.</span>
