Team advice

I would like some advice on my team
Such as what items on my Pokémon
And if i Should Change my Team
All help is Appreciated please reply
My inspiration for my team was To have a team no Weakness and alot of rock types fo tyranitar sandstorm
Aggron
Tyranitar
Garchomp
Terrakion
Amoonguss
Volcaronas

Can you tell us what moves you want
to give them?

I'd suggest replacing volcorona with heatran since it absorbs fire attk. And I would recommend jellicent since it can take fire/ water / fight well, which are dangerous for your team.
T-tar chople berry/ leftovers
Terrakion life orb/choice band
Garchomp life orb
Volcorona leftovers/life orb/choice specs
Aggron choice band
Amoonguss black sludge

Volcaronas: overheat silver wind will o wisp flamethrower
Tyranitar: gigs impact dragon tail crunch earthquake
Terrakion: healing hand retaliate rock slide scared sword
Garchomp: dragon rush dig surf shadow claw
And amoongoss and Aggon aren't high enough level

Amoonguss: spore, sludge bomb, giga drain,Stun spore
Garchomp: swords dance, outrage, earthquake, fire fang ( life orb set)
T-tar: stealth rock, crunch, fire blast, stone edge
Terrakion: close combat, stone edge , x-scissor, quick attack (choice band)

Rest I have no clue

Volcarona is better off setting up Quiver Dances then smashing things. It's also too physically defensively weak for support:
-Quiver Dance
-Fiery Dance/Fire Blast
-Bug Buzz
-Hidden Power (Rock/Ground)/Giga Drain
Nature: Timid
EVs: 252 SAtk/4 SDef/252 Spe
Item: Life Orb

or
-Quiver Dance
-Bug Buzz
-Fire Blast/Fiery Dance
-Roost
Nature: Timid
EVs: 252 HP/240 Def/16 Spe
Item: Leftovers

or
-Quiver Dance
-Bug Buzz
-Fire Blast/Fiery Dance
-Rest
Nature: Modest
EVs: 160 HP/236 SAtk/112 Spe
Item: Chesto Berry

Tyranitar has a wide movepool to take advantage of. Never use Hyper Beam-style moves competitively; they leave you a sitting duck the next turn:
-Stealth Rock
-Crunch
-Pursuit
-Fire Blast/Stone Edge/Superpower
Nature: Sassy/Careful
EVs: 252 HP/4 Atk/252 SDef
Item: Leftovers
Ability: Sand Stream

or
-Crunch
-Pursuit
-Stone Edge

EVs: 180 HP/252 Atk/76 Spe (Adamant) or 4 HP/252 Atk/252 Spe (Jolly)
Item: Choice Band (Adamant)/Choice Scarf (Jolly)
Ability: Sand Stream

Terrakion needs some serious redoing. It has stronger STABs in Close Combat and Stone Edge:
-Rock Polish
-Swords Dance
-Close Combat
-Stone Edge
Nature: Jolly/Adamant
EVs: 4 HP/252 Atk/252 Spe
Item: Life Orb/Air Balloon/Rock Gem

or
-Close Combat

Garchomp learns Earthquake. Use it:

Looking at this team, you're vulnerable to bulky Waters. Ferrothorn fills in both Amoonguss' and Aggron's roles in one slot:
-Stealth Rock/Spikes
-Leech Seed
-Power Whip
-Gyro Ball/Thunder Wave/Protect
Nature: Relaxed
EVs: 252 HP/88 Def/168 SDef
