LinkedIn’s Pinpoint #861 for September 8, 2026 challenges players to discover the connection between five clues related to the structure and physical features of our planet. The puzzle moves from the layers deep beneath the surface to the tectonic plates that shape Earth’s surface and the magnetic poles at its northern and southern ends.
Each clue is connected to Earth and its major physical components or features. Here’s how they connect:
Crust
The crust is Earth’s outermost solid layer. It is relatively thin compared with the layers beneath it and forms the surface on which we live.
Earth’s crust is generally divided into continental crust, which makes up the continents, and oceanic crust, which lies beneath the oceans. The crust, together with the rigid uppermost mantle, forms the lithosphere.
Mantle
The mantle lies beneath Earth’s crust and makes up most of the planet’s volume. It is composed primarily of silicate rocks and extends thousands of kilometers toward the outer core.
Although the mantle is solid, it can deform and flow extremely slowly over geological timescales. Movement within the mantle is closely connected with the processes that drive plate tectonics.
Core (mostly iron and nickel)
Earth’s core is the planet’s deepest major layer. It is primarily composed of iron and nickel and is divided into the outer core and inner core.
The outer core is liquid, while the inner core is solid because of the enormous pressure at Earth’s center. Movement of electrically conductive material in the liquid outer core helps generate Earth’s magnetic field.
Tectonic plates
Tectonic plates are large pieces of Earth’s lithosphere that move slowly over the softer material beneath them.
Their movement is responsible for many major geological processes, including earthquakes, volcanic activity, mountain building, and the creation of oceanic crust. The boundaries where plates interact are particularly active areas of geological change.
Magnetic poles (North+South)
Earth has magnetic poles associated with its global magnetic field. The magnetic field is generated largely by processes occurring in the planet’s liquid outer core.
The magnetic poles are not exactly the same as the geographic North and South Poles, and their positions can change over time. Earth’s magnetic field also helps protect the planet from charged particles coming from the Sun.
Parts of the Earth!
The final clue confirms the category. The crust, mantle, and core are Earth’s major internal layers, while tectonic plates and magnetic poles are important physical features associated with the planet.
Together, the five clues point to different parts or major features of Earth.
Final Answer
Parts of the Earth!
