Question

question 4 cite two specific observations from your data table or diagram that support your claim - write 2 complete sentences and include detailed, accurate observations. - optional sentence starters: - at a ____ boundary, i observed __, which formed __. - in my model, __ happened when the plates __, creating ____.

Explanation:

To answer this, we assume a context of plate tectonics (a subfield of Natural Science, specifically Geology which falls under Geography or Earth Science in the given list). Here are two observations:

1. For a convergent boundary (where plates collide), we can observe that one plate subducts beneath another, which forms deep ocean trenches and volcanic arcs (e.g., the Mariana Trench at the Pacific - Philippine plate boundary).
2. At a divergent boundary (where plates move apart), I observed magma rising to the surface, which formed new oceanic crust (like the Mid - Atlantic Ridge where the North American and Eurasian plates separate).

Answer:

1. At a convergent boundary, I observed one tectonic plate subducting beneath another, which formed a deep ocean trench (e.g., the Mariana Trench).
2. In my model, new oceanic crust formation happened when the plates moved apart at a divergent boundary, creating a mid - ocean ridge (e.g., the Mid - Atlantic Ridge).
