Stonehenge consists of a circular arrangement of large standing stones, known as sarsens, which are surrounded by a circular earthwork. The sarsens are arranged in a pattern of post-and-lintel construction, with horizontal stones (lintels) resting on vertical stones (posts). Inside the circle, there are smaller bluestones arranged in an inner oval. The precise arrangement is thought to have astronomical significance, aligning with the solstices and indicating its importance in ancient rituals.

rocks
The major stones of Stonehenge are mostly sandstone, others are igneous rocks.
sandstone and healing rocks that they brought from Africa
I'm answering myself when I say it's a calender!

erosion is causing rocks to dissolve
Big blocks of rocks
Stonehenge has not been used for thousands of years so no one knows the answer to this.
The outcrop sedimentary rocks at Stonehenge are the Late Cretaceous, Santonian Age, calcium carbonates. The outcrop sedimentary rocks comprise the first construction material used by the Stonehenge builders. This material is approximately 85 million years old. These rocks are locally called the Seaford Chalk Formation (Stonehenge White Chalk). The oldest limestone sedimentary rocks at Stonehenge are the Mississippian Period (Early Carboniferous), Arundian Age, calcium carbonates. The Mississippian Period limestone sedimentary rocks comprise the first (1st) foreign construction material used by the Stonehenge builders. This material is approximately 340 million years old. These rocks are locally called the Birnbeck Limestone Formation (Stonehenge Whitestones). The volcanic rocks (oldest geologically) at Stonehenge are the Ordovician Period intrusive igneous diabases (dolerites), and extrusive igneous felsites (rhyolites) and tuffs (basic). The Ordovician Period igneous rocks comprise the second (2nd) foreign construction material used by the Stonehenge builders. This material is approximately 470 million years old. These rocks are locally called the Ordovician Volcanics (Stonehenge Bluestones). The oldest sandstone sedimentary rocks at Stonehenge are the Silurian and Devonian Period micaceous sandstones. The Silurian and Devonian Period sedimentary sandstone rocks comprise the third (3rd) foreign construction material used by the Stonehenge builders. This material is approximately 417 million years old. These rocks are locally called the Old Red Sandstone Formation (Stonehenge Coshestons). The youngest sandstone sedimentary rocks at Stonehenge are the Oligocene and Miocene Period silicates. The Oligocene and Miocene Period sandstone sedimentary rocks comprise the fourth (4th) foreign construction material used by the Stonehenge builders. This material is approximately 24 million years old. These rocks are locally called the Reading Formation (Stonehenge Sarsens). http://www.bgs.ac.uk
Sedimentary rocks are the type of rocks that are mostly arranged in layers. The way in which the layers are arranged is commonly called bedding.
because the rocks are old and strange
