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 |

With erosion and gravity and all the fun sciencey stuff the earth is constantly changing

The Earth is not a sphere because gravity is always compressing the Earth and it changes the shape over time.

Earth is always changing as it rotates because of force.

i would say, long story short, erosion

Erosion chips away at Earth slowly taking bits out. Thus making it non spherical.

Because earth has things like mountains, trenches, and elevations.

Erosion and techtonic plates change the shape of the earth

Erosion can create dips in the Earth, and the pushing of the tectonic plates can push certain parts of the Earth upwards.

Because as the Earth rotates over time, the force of gravity changes and pushes on the Earth

It would be inaccurate because of gravity, erosion, and the plates moving around

The north and south poles are flatter

The earth cant be a perfect square because it has montains and different levels of the sea floor

The earth is changing because of erosion, so it's not a perfect sphere.

because there are different elevations on the earth and the earth is constantly being eroded away so it won't be perfectly smooth

if it was a perfect sphere it would be smooth and not have any change in geography, but it does, it has mountains and valleys and erosion changes its shape

The earth can’t be a perfect sphere, conditions like erosion, weathering, and human construction exist.

The earth is not perfectly round because gravity, erosion, and the plates moving around.

The earth isn’t a perfect sphere because there are many landforms that change the earth’s shape, and erosion has changed the shape of the earth overtime as well.

The earth isn't a complete sphere because it has undergone natural processes like erosion

The earth has different geographical formations like mountains and valleys, and natural weathering like erosion.

The earth is shaped like it is because over time it changed shape due to things like drifting and erosion.
