The first 6 seals are discussed in great detail at Revelation 6:1-17 which discusses the first 4 seals and the riders on the 4 horses:
6:1 And I saw when the Lamb opened one of the seven seals, and I heard one of the four living creatures+ say with a voice like thunder: “Come!”
2 And I saw, and look! a white horse, and the one seated on it had a bow; and a crown was given him,+ and he went out conquering and to complete his conquest.
3 When he opened the second seal, I heard the second living creature say: “Come!”
4 Another came out, a fiery-colored horse, and it was granted to the one seated on it to take peace away from the earth so that they should slaughter one another, and he was given a great sword.
5 When he opened the third seal, I heard the third living creature say: “Come!” And I saw, and look! a black horse, and the one seated on it had a pair of scales in his hand.
6 I heard what sounded like a voice in the midst of the four living creatures say: “A quart of wheat for a de·narʹi·us and three quarts of barley for a de·narʹi·us; and do not harm the olive oil and the wine.”
7 When he opened the fourth seal, I heard the voice of the fourth living creature say: “Come!”
8 And I saw, and look! a pale horse, and the one seated on it had the name Death. And the Grave was closely following him. And authority was given them over the fourth part of the earth, to kill with a long sword and with food shortage and with deadly plague and by the wild beasts of the earth.
9 When he opened the fifth seal, I saw underneath the altar the souls of those slaughtered because of the word of God and because of the witness they had given.
10 They shouted with a loud voice, saying: “Until when, Sovereign Lord, holy and true, are you refraining from judging and avenging our blood on those who dwell on the earth?”
11 And a white robe was given to each of them, and they were told to rest a little while longer, until the number was filled of their fellow slaves and their brothers who were about to be killed as they had been.
12 And I saw when he opened the sixth seal, and a great earthquake occurred; and the sun became black as sackcloth made of hair, and the entire moon became as blood,
13 and the stars of heaven fell to the earth as when a fig tree shaken by a high wind drops its unripe figs.
14 And the heaven departed as a scroll that is being rolled up, and every mountain and every island was removed from its place.
15 Then the kings of the earth, the high officials, the military commanders, the rich, the strong, every slave, and every free person hid in the caves and among the rocks of the mountains.
16 And they keep saying to the mountains and to the rocks: “Fall over us and hide us from the face of the One seated on the throne and from the wrath of the Lamb,
17 because the great day of their wrath has come, and who is able to stand?”
The 7th Seal Revelation 8:1-5 says:
8:1 When he opened the seventh seal, there was silence in heaven for about half an hour.
2 And I saw the seven angels who stand before God, and seven trumpets were given to them.
3 Another angel, holding a golden incense vessel, arrived and stood at the altar, and a large quantity of incense was given him to offer it with the prayers of all the holy ones on the golden altar that was before the throne.
4 The smoke of the incense from the hand of the angel ascended with the prayers of the holy ones before God.
5 But right away the angel took the incense vessel, and he filled it with some of the fire of the altar and hurled it to the earth. And there were thunders and voices and flashes of lightning and an earthquake.
Revelation 8:6-13 says:
8:6 And the seven angels with the seven trumpets prepared to blow them.
7 The first one blew his trumpet. And there was hail and fire mingled with blood, and it was hurled to the earth; and a third of the earth was burned up, and a third of the trees were burned up, and all the green vegetation was burned up.
8 The second angel blew his trumpet. And something like a great mountain burning with fire was hurled into the sea. And a third of the sea became blood;
9 and a third of the living creatures in the sea died, and a third of the ships were wrecked.
10 The third angel blew his trumpet. And a great star burning like a lamp fell from heaven, and it fell on a third of the rivers and on the springs of waters.
11 The name of the star is Wormwood. And a third of the waters turned into wormwood, and many of the people died from the waters, because these had been made bitter.
12 The fourth angel blew his trumpet. And a third of the sun was struck and a third of the moon and a third of the stars, in order that a third of them might be darkened and the day might not have light for a third of it, and the night likewise.
13 And I saw, and I heard an eagle flying in midheaven say with a loud voice: “Woe, woe, woe to those dwelling on the earth because of the rest of the trumpet blasts of the three angels who are about to blow their trumpets!”
Revelation 9:1-21 says:
9 The fifth angel blew his trumpet. And I saw a star that had fallen from heaven to the earth, and the key to the shaft of the abyss was given to him.
2 He opened the shaft of the abyss, and smoke ascended out of the shaft like the smoke of a great furnace, and the sun was darkened, also the air, by the smoke of the shaft.
3 And locusts came out of the smoke onto the earth, and authority was given to them, the same authority that the scorpions of the earth have.
4 They were told not to harm the vegetation of the earth or any green plant or any tree, but only those people who do not have the seal of God on their foreheads.
5 And it was granted the locusts, not to kill them, but to torment them five months, and their torment was like torment by a scorpion when it strikes a person.
6 In those days people will seek death but will by no means find it, and they will long to die, but death will flee from them.
7 And in appearance the locusts resembled horses prepared for battle; on their heads were what seemed to be crowns of gold, and their faces were like human faces,
8 but they had hair like women’s hair. And their teeth were like those of lions,
9 and they had breastplates like iron breastplates. And the sound of their wings was like the sound of horse-drawn chariots rushing into battle.
10 Also, they have tails with stingers like scorpions, and in their tails is their authority to hurt the people for five months.
11 They have over them a king, the angel of the abyss. In Hebrew his name is A·badʹdon, but in Greek he has the name A·polʹlyon.
12 The one woe is past. Look! Two more woes are coming after these things.
13 The sixth angel blew his trumpet. And I heard one voice from the horns of the golden altar that is before God
14 say to the sixth angel who had the trumpet: “Untie the four angels who are bound at the great river Eu·phraʹtes.”
15 And the four angels who have been prepared for the hour and day and month and year were untied to kill a third of the people.
16 The number of the armies of cavalry was two myriads of myriads; I heard the number of them.
17 And this is how I saw the horses in the vision and those seated on them: They had fire-red and hyacinth-blue and sulfur-yellow breastplates, and the heads of the horses were like the heads of lions, and fire and smoke and sulfur came out of their mouths.
18 A third of the people were killed by these three plagues, by the fire and the smoke and the sulfur that came out of their mouths.
19 For the authority of the horses is in their mouths and in their tails, for their tails are like serpents and have heads, and with these they inflict harm.
20 But the rest of the people who were not killed by these plagues did not repent of the works of their hands; they did not stop worshipping the demons and the idols of gold and silver and copper and stone and wood, which can neither see nor hear nor walk.
21 And they did not repent of their murders nor of their spiritistic practices nor of their sexual immorality nor of their thefts.
Revelation 10:1-11 says:
10:1 And I saw another strong angel descending from heaven, arrayed with a cloud, and a rainbow was on his head, and his face was like the sun, and his legs were like pillars of fire,
2 and he had in his hand a little scroll that had been unrolled. And he set his right foot on the sea, but his left one on the earth,
3 and he cried out with a loud voice just as when a lion roars. And when he cried out, the voices of the seven thunders spoke.
4 Now when the seven thunders spoke, I was about to write, but I heard a voice out of heaven say: “Seal up the things the seven thunders spoke, and do not write them down.”
5 The angel whom I saw standing on the sea and on the earth raised his right hand to heaven,
6 and he swore by the One who lives forever and ever, who created the heaven and the things in it and the earth and the things in it and the sea and the things in it: “There will be no delay any longer.
7 But in the days when the seventh angel is about to blow his trumpet, the sacred secret that God declared as good news to his own slaves the prophets is indeed brought to a finish.”
8 And I heard the voice out of heaven speaking again with me and saying: “Go, take the opened scroll that is in the hand of the angel who is standing on the sea and on the earth.”
9 I went to the angel and told him to give me the little scroll. He said to me: “Take it and eat it up, and it will make your stomach bitter, but in your mouth it will be sweet like honey.”
10 I took the little scroll out of the hand of the angel and ate it and in my mouth it was sweet like honey, but when I had eaten it, my stomach was made bitter.
11 And they said to me: “You must prophesy again about peoples and nations and tongues and many kings.”
