Pyramids

They used basalt in ancient Egypt to make walls for protection!

Frontline trenches were usually about seven feet deep and six feet wide. The front of the trench was known as the parapet. The top two or three feet of the parapet and the parados (the rear side of the trench) would consist of a thick line of sandbags to absorb any bullets or shell fragments.

In a trench of this depth it was impossible to see over the top, so a two or three-foot ledge known as a fire-step, was added. Trenches were not dug in straight lines. Otherwise, if the enemy had a successive offensive, and got into your trenches, they could shoot straight along the line. Each trench was dug with alternate fire-bays and traverses.

Duck-boards were also placed at the bottom of the trenches to protect soldiers from problems such as trench foot. Soldiers also made dugouts and funk holes in the side of the trenches to give them some protection from the weather and enemy fire.

The front-line trenches were also protected by barbed-wire entanglements and machine-gun posts. Short trenches called saps were dug from the front-trench into No-Man's Land. The sap-head, usually about 30 yards forward of the front-line, were then used as listening posts.

Behind the front-line trenches were support and reserve trenches. The three rows of trenches covered between 200 and 500 yards of ground. Communication trenches, were dug at an angle to the frontline trench and was used to transport men, equipment and food supplies.

Most were made out of Stone, though some were made out of mud bricks or mud bricks and stone.

yes, they are thousands of years old if you mean us us

but no if you are talking about the human race

All it takes to Build a pyramid is a little pixie dust and your imagination. with that, anything can come true! I'm KIDDING! it took thousands of slaves and many years to build the pyramids.

According to other resources, Thutmose I was the first pharaoh to have a tomb built in The Valley of The Kings. But, maybe or maybe not,king Amenhotep (the kind before Thutmose I) could've have a tomb built in The Valley OF The Kings first. But it's likely that Thutmose I was the 1st one.

Mortar. Although mortar that dries whilst packing around stonework will adhere the stones to form a structure.

you can see them all over the world but Egypt has the most famous pyramids of all

The biggest pyramid is the Great Pyramid of the 4th dynasty Pharaoh Khufu at Giza near modern Cairo. Built during his reign 2589-2566BC.

It is 480ft high and 750ft on each side of the base. It contain about 2.3 million limestone and granite blocks, a total weight of 6.4 million tons.

Yes, it is. The Great Sphinx in Giza, Egypt, is the oldest monumental structure known to man.

The Pyramid of the Sun is mainly made of rubble and brick and the surface of this pyramid was covered in volcanic stone.

The first pyramid in Egypt was the step pyramid of king Djoser, also known as Zoser.

It was a step pyramid, consisting of mastabas placed on top of each other, and designed by his architect Imhotep.

Unclear on exactly what you are asking here because I'm not sure if you didn't mean to ask "When" instead of what. Imhotep was the first builder of a pyramid for his Pharaoh Djoser/Zoser (spelling varies) ca 2630–2611 BCE. He began building what was to have been the largest mastaba, from the word meaning bench due to there long flat rectangular single story appearance with little to no exterior decoration, which had been the previous burial chambers of the earliest Pharaohs but he just kept adding smaller mastabas on top of the first creating what we know as the Step Pyramid and the first Pyramid.

the ancient egyptians built them to burry their kings in the early times. they stopped using them later on because they were being robbed. they then started using under ground tombs so it was harder to rob.

A large number of people perhaps 10,000 to 30,000 at any one time:

1. Skilled workers such as masons, carpenters, smiths (coppersmiths rather than blacksmiths), rope makers and surveyors.

2. the supervisors scribes, foremen in charge of the labour gangs

3. thousands of slaves who did all the heavy and often dangerous unskilled work.

These huge structures were built without the help of equipment such as cranes and bulldozers. The ancient Egyptians used tools of copper, a softer metal than iron. Wooden wedges to help prise the stone from the quarry face and levers to help put the stones in place were also used in building the pyramids. Building a pyramid was dirty, difficult and dangerous work. It required meticulous planning and organization. Two varieties of stone were used, limestone and granite. The limestone which made up the bulk of the pyramid was quarried locally. The granite had to be brought from the quarries at Aswan to where the pyramid was being built. They were transported on the Nile River in massive reed boats. The average weight of one of the pyramid's stone block is two and half tonnes. Some of the Aswan blocks, however, weighed up to 70 tonnes. To complete the Great Pyramid at Giza, one stone block was quarried, shaped and placed in position every two minutes for 20 years. It was this hard monotonous work that was done by slaves. Building plans showing how the pyramid was built have never been found, experts use present knowledge about construction to make some intelligent guesses. One can see though how the ancient Egyptians were ingenious people as you look at the work it took to build a pyramid. The limestone blocks were cut out in the quarries close the pyramid site. Most of these blocks were roughly cut to size. Only where precision was needed were they dressed and trimmed often to an exacting standard by the masons. Once the limestone blocks quarried they were hauled on sledges along a causeway by gangs of slaves. Water was poured around the sledges to help them slide. A spiralling ramp of mud, brick and rubble was used to haul the blocks to the level where building was going on. Once at the working level the blocks were man-handled into position by levers and brute force by further gangs of slaves called setters. Once relieved of their load the hauliers would then make their weary way back down the ramp to start the whole process again. A canal connected the pyramid site with the Nile. Here granite brought down from Aswan and fine limestone from Tura was unloaded. These were special stones that involved a lot of preparation in their quarrying, dressing and transportation. A vast amount of labour, of quarrymen, masons and of course slaves.

Well, having animal drawn wheeled vehicles could have made the Egyptians work more easier because with out the vehicles people would have to be carrying around the heavy materials when building the pyramids.

the pyramid was invetend for the kings so when they die the put there bodies inside the pyramid for them it was like an honor some ppl say aliens invetend it but the alien thing is weird

The wealthy of ancient Egypt lived good they would normally live in big fancy for back then houses and usually in the country away from all the noise. The slaves did lead very hard lifes if they were miners or something like that they would hurt and it would be bad. The poor lived in the city normally in these little apartment buildings that were stinky smelly and just gross something that i would never live in.

The eyptian built the pyramids because the kings (pharoahs) wanted to show everyone how great they were. The peak (top) of the pyramid was meant to be the "stariway to heaven". This was usually the tomb of the pharoah. He would put all the belonging he would need for the atferlife. They even put ships to lead the to heaven in there!

The pyramid originally stood 62 metres (203 ft) tall,

with a base of 109 × 125 m (358 × 410 ft)

Many things have been buried under the sand, but not the pyramids.

Wrong. They were discovered half buried in the sand. I think they were buried by humans or aliens and then the wind half uncovered them. Archaeologist believe that the wind half buried them
