The two most abundant elements in the Earth's crust are oxygen and silicon. When you combine them, you get silicon dioxide; which depending on the exact form it takes is glass or quartz or sand.
They tend to combine further with other elements to produce silicate rocks.
The two most abundant elements in Earth as a whole are iron and oxygen. When you combine them, you get iron oxide (rust, hematite, magnetite). The reason iron isn't more common in the crust than it is is that it's heavy and has been concentrated in the Earth's core.
