Moss Weathering-
Cobblestone, Stone Bricks, Bricks + their variants will slowly convert to their mossy versions over time when they are within two blocks of a Moss Block, Moss Carpet, Vines, or Water. Stone and its slab and stairs cannot convert naturally over time but can be mossed and shorn manually.

Moss Shearing-
Using Shears on any moss covered block will now convert that block to its un-mossy version and drop a Moss Clump.

Manual Mossing-
Using a Moss Clump on any un-mossy block that has a mossy form will make the block mossy.

Bonemeal Moss Spreading-
Using Bone Meal on any mossy block will cause any nearby blocks with mossy versions to also become mossy.

Natural Brick Cracking-

Any type of brick block with a cracked version (including stairs and slabs which this mod adds) has a chance to slowly convert to that cracked version over a very long period of time. Cracks are much more likely to form in blocks next to an already cracked block.

Manual Brick Cracking-
Using any pickaxe on any brick block with a cracked version will now convert that block to its cracked version, dropping a brick item that corresponds to the type of brick cracked.

Brick Repairing-
Using any brick item on a cracked brick block of the matching type will convert the cracked block to its uncracked version. Once a cracked brick has been repaired using a brick item, it will no longer be able to crack naturally over time.

Bark Stripping-

Using an axe on any log block will convert it to its stripped form and drop a corresponding bark item

Bark Unstripping-

Using the correct bark item on a stripped log will convert it back to its unstripped form

Crafting-
Unstripped wood and logs can be crafted by combining them with their bark item.

Wood blocks can be crafted by combining an unstripped log with its bark.

3 Paper can be crafted using 3 Birch Bark.

Mulch Blocks-
Mulch blocks can be crafted by combining 1 dirt, 2 bark of any type, 1 bone meal, 1 soot and 1 moss clump.
Mulch, which look and function like carpets, can be crafted with 2 Mulch Blocks.
Mulch Blocks reduce fall damage when landed upon.
Mulch Blocks create a signal fire when placed below a campfire. 
Crops can be grown on Mulch Blocks if they have been Soaked.
Mulch Blocks can become soaked if a bucket is used on it or if it is rained on or placed in a wet biome. Mulch will dry out over time in hot biomes.

Nulch Blocks, the Nether counterpart to Mulch, can be crafted by combining 1 netherrack, 2 scales of any type, 1 magma cream, 1 soot and 1 nether wart.
Nulch carpets, can also be crafted with 2 Nulch Blocks.
Nulch Blocks also reduce fall damage when landed upon.

Natural Rusting- 
Plate Iron, Cut Iron, Iron Trapdoors, Iron Doors and Iron Bars can all become rusted over time.
Rust can only be removed when it is in its first stage (Exposed) beyond that, the rust is permanent.
Waxing the block using a honeycomb will prevent rusting.
There are four stages of iron blocks in this mod; Clean, Exposed, Weathered and Rusted.
Any iron block exposed to air can become Exposed over time.
A block needs to be exposed to rain in order for it to become Weathered.
A block needs to be in contact with water in order to become Rusted.
All of these stages can be sped up if you place the iron next to a Bubble Column.

Rusty Delay-
After receiving a redstone signal, iron doors and trapdoors will take longer to close the more rusted they are. Fully rusted doors and trapdoors toggle between open and closed whenever they get a signal.

Manual Rusting- 
Using a wet sponge on a rustable block causes the block to increase one stage of rusting.
Using any axe on an Exposed rusted block can reduce the rust stage back to clean.

Soot can be obtained by right clicking on a campfire or fire block to extinguish them.
Soot can be placed on all sides of blocks, like Glow Lichen.
Soot drops when broken by a piston
Soot can be used to smelt 0.5 items in a furnace. 

Natural Soot-
Soot will appear over time on solid surfaces above fire blocks and next to campfire smoke.

-Fire has a chance to burn away nearby grass blocks, converting them to dirt

-Ash Blocks are crafted with 9 soot and have a Smoldering state that acts the same as soot’s

-Ash Blocks are affected by gravity

-Soot and Ash have Smoldering blockstate which it can convert to if placed next to a magma block or if flint and steel is used on it

-Smoldering Ash and Soot will emit ember particles

-Right clicking smoldering Ash or Soot or letting it sit out in the rain will convert it back to normal

-Smoldering Soot and Ash do damage to entities that walk over them except when those entities are wearing boots frost walker

-Icicles generate above y=96 in icy biomes

-Icicles melt in hot biomes or when the light level is above 13

-Icicles fall when hit by any projectile

-Icicles grow beneath ice blocks with water above them while its sunny

-Ice blocks now melt in hot biomes during the day

-Icicles can be eaten

-Leaf Piles will build up below leaves that were generated as part of a tree (non-player placed)

-Leaf piles for all leaf types + Azalea Flower Piles
-Leaf piles can fall onto and be placed on water

-6 Leaf piles can be crafted using three of the respective leaf block (like crafting snow layers)

-Leaf piles will create leaf particles when walked through

-Using sears on Flowering Azalea Leaves will drop Azalea Flowers

-Azalea flowers can be used on azaleas, azalea leaves and azalea leaf piles to make them flowering

-Using bone meal on any flowering block will spread the flowers to nearby blocks that can be flowering

-Grass Blocks will grow grass on top of themselves over time

-Depending on the biome, Grass Blocks can also grow a variety of flowers and Saplings

-Grass will grow into Tall Grass

-Ferns will grow into Large Ferns

-Mycelium will grow red and brown mushrooms on top of itself

-Podzol will grow Ferns

-Rooted Dirt will grow Hanging Roots below itself

-Weeds will occasionally grow on Farmland even if there are already crops on that block

-Weeds are much more likely to appear on farmland when a fully grown weed is nearby

-Weeds will not grow on Mulch

-Nylium will grow its respective roots and fungi

-Coral blocks will grow their respective Coral Plants and Fans if under water and in a Warm Ocean biome
