How do mountains form?
elixir [45]
Mountains are formed by the movements of the tectonic plates and Earth's. Movements deep beneath the Earth's surface cause a variety of reactions, and the results in different types of mountains. Mountains can form as a result of the volcanic activity, the collision of 2 tectonic plates or a movement along a fault line.

This passage is mainly about
N76 [4]

Answer:

This passage is mainly about asteroids striking Earth.

Explanation:

The presented passage is mostly focusing on asteroids striking Earth. It is something that has been happening since Earth has formed, and it will happen in the future as well. The vast majority of the asteroids don't really have any impact on Earth, but some have an impact that is devastating and long-lasting.

In the earlier stages of Earth, many more asteroids were falling on the surface, and the main reason for that has been the lack of atmosphere or a very thin atmosphere. As the atmosphere started to take shape and became similar to what is nowadays, the asteroid impacts decreased significantly because the atmosphere was managing to burn them and break them apart. This is not possible with all asteroids though, as some are so big and fall under an angle where the atmosphere doesn't really have any impact on them so when they fall on the surface they are able to cause sudden climatic changes, mass devastation, and mass extinction of species. Such an asteroid will be in a direction to hit Earth in the future for sure, the question remains will humans with their technology be able to prevent an impact or not.

1. Which of the following is a correct description of a tornado? (1 point)
spayn [35]
<h2>Answer: Option D</h2><h2 />

Option A, "a large swirling, low-pressure system that forms over the warm Atlantic Ocean"  is incorrect because tornadoes do not form over water. That would be a hurricane.

Option B, "a winter storm with wind speeds of at least 56 km/h and low visibility" Is incorrect because tornadoes do not form in cold weather. That would be a blizzard.

Oa boundary between two air masses of different density, moisture, or temperature​ption C, "a violently rotating column of air in contact with the ground" is correct <u>because tornadoes are columns of air that rotate due to warm air and cold air colliding.</u> They usually occur during a thunderstorm.

Option D, "a boundary between two air masses of different density, moisture, or temperature​" is incorrect because tornadoes are not based on air mass, density, moisture, or temperature. This would be a front.

Why are ocean fossils found on top of the rocky mountains?
Anna35 [415]
Let's start from the beginning. 

<span>Millions and millions of years ago, planet Earth was absolutely crowded with volcanoes. </span>

<span>As you may know, volcanoes release steam and gasses. </span>
<span>As the years went by, the gasses released from volcanoes formed the atmosphere around the planet, which prevented the steam from disappearing into outer space. </span>
<span>The steam eventually, in cycles, began to fall back to Earth. Viola, rain had just been "invented". </span>

<span>As more and more rain fell, considering almost every surface of the planet was volcanic, the water began to build up and "flood" the planet. Many active volcanoes had now been transformed into underwater volcanoes. </span>

<span>As more and more years went by, eventually, bacteria in the water slowly began to evolve, first into jelly-fish like creatures, then tadpole-like creatures, leading all the way up to large ferocious underwater reptiles, amphibians and fish. </span>

<span>As the planet started to warm up, probably by methane gasses released from the prehistoric underwater creatures, the water levels on Earth began to drop again. At the same time, the active underwater volcanoes were creating new landmasses, either by lava cooling on the surface of the water or tectonic plates pushing the volcano above sea level. </span>

<span>So, this, is how fossils of sea creatures ended up in high land-based mountains. </span>
<span>Because millions of years ago, most of Earth was underwater until the water levels dropped or lands "grew" higher. </span>
<span>The Rocky Mountains were once underwater. </span>


<span>If you take a look at images of the Grand Canyon in the United States, you'll see that it resembles the deep caverns and canyons that you find at the bottom of oceans. </span>
<span>That's because the Grand Canyon WAS at the bottom of an ocean.</span>
