| Central Question: Why is the earth's surface shaped like it is? What processes have caused it to be that way? Guiding Thought Question: Why is it inaccurate to say that the earth is a perfect sphere? Today's Learning Objective: Students will be able to explain the principles of erosion and how the earth is continually shaped. Students will take notes on the types of erosion and then conduct a map and field study to find evidence of different types of geomorphology |  |

The Earth's surface is the way it is because of the movement of tectonic plates over billions of years. They push together creating mountains, and move apart creating oceans.

Similar animal that have been distributed across the globe due to migrations, the breaking-apart of the continents, and more are forced to adapt to their environment in order to survive.

It is unaccurate to say that the earth is a perfect sphere because there are divits, mountains, hills, trenches, etc. The earth cannot be a perfect sphere because the land is not perfectly smooth and straight.

Because it is an ellipsoid. It is thicker at the equator because it's rotation causes it to stretch out a little there.

The Earth has many layers and doesn't have a flat surface, so obviously it's not a perfect sphere.

The earth has mountains and valleys that make the land not flat

The Earth is not perfectly circular or in a perfect sphere because of the land on Earth. Not all the land on earth is equal to one another. Having a single small hill over all the land on Earth would no longer make it a perfect circle to put it into that perspective.

Earth’s tectonic plates do not cover the Earth in a perfect sphere, as water and other natural process warp it’s surface.

The elevations of the earths surface varies juristically from region to region. Not everything is at ocean level.

The Earth is not a perfect sphere because continents are continuing to move and shift.

Because there are many differences in elevations on the earth with mountains, hills, some places being an elevation of 6000 ft but then some being at sea level.

It would be inaccurate because the earth and its tectonic plates move so it will never be perfectly round.

movement in the tectonic plates in the crust, wind and water erosion, and deposition—shape features on Earth's surface.

The earths surface is the way that it is because of the movement of tectonic plates over time. As the plates pull apart it makes valleys and canyons and as they converge they make mountains.

You can say that its a perfect sphere because it has mountains and valleys so the circumference is not even at all spots therefore it is not a perfect sphere.

since the earth has a bunch of geological stuff going on, such as mountains and stuff, it isn’t a perfect sphere!

The earth is not a perfect shape because the land is not flat and the continents are continuing to move.

Over the many years of Earth’s existence, tectonic plates have continued to interact with one another and form mountains, valleys, etc. The process of erosion and other geological processes have broken down land and formed different shapes.

Because of the tectonic plates that the crust lays on and moves across the mantel and grinds, and clashes against others.

Because of the trenches, mountains and different changes in the land

isn't its orbit as well as its shape an ellipsoid? 8/26/2021 12:30:30 pm

The Earth's plates are not shaped to be a sphere and it has lumps on it instead of being perfectly rounded Leave a Reply. |
