In the beginning (starting 4.567 Ga), Earth's surface consisted of what is called a "magma ocean"; i.e. there was no crust, yet. The first rocks formed throuh cooling of this magma ocean at least 4.4 Ga (possibly earlier). Hence, they are igneous since they formed through cooling of magma.
The hydrosphere (oceans, rivers, etc.) and consequently sedimentation and formation of sedimentary rocks came later.
What else can I help you with?
Was Igneous rocks were the first rock type to appear on earth?
Yes, by their constituents being the planet's primary materials. Sedimentary rocks started to form only when erosion of the original land created the sediment. Metasediments came later still, as plate tectonics started to metamorphose the early sediments.
If you were to tunnel into the crust of the earth what kind of rock would you most likely find there?
If you were to tunnel into the crust of the Earth, you would most likely find igneous rocks. These rocks are formed from the solidification of molten magma below the Earth's surface. Examples of igneous rocks include basalt, granite, and diorite.
What do you call igneous rocks that have crystallized inside the Earth?
GranitesDioritesGabbrosPegmatitesDykesSillsLayered Igneous intrusions
Which igneous rocks form below earth's surface?
Igneous rocks that form below the Earth's surface are called intrusive igneous rocks. Examples include granite, diorite, and gabbro. These rocks cool and solidify slowly, allowing large crystals to form.
What term describes igneous rocks that crystallize inside the Earth?
Intrusive igneous rocks.
Which came first sedimentary igneous metamorphic rocks?
Metamorphic rock would probably have been the first rock type formed after the initial formation of the first igneous rock. Sedimentary rock formation relies on weathering and erosion, whereas metamorphic rock can be created by heat and pressure. It's likely that rock was metamorphosed before weathering existed .
What are igneous rocks that form on earth surface?
igneous rocks that form on earth's surface
What Igneous rocks are cooled within the Earth?
Intrusive igneous rocks.

Igneous rocks formed from lava on Earth's surface?
Extrusive igneous rocks.

What is the percentage of Igneous rocks?
90% of Earth's upper crust is made of Igneous rocks.
Rocks created when melted rocks from inside earth cools?
igneous intrusive

Igneous rocks that form below the Earth's surface are called intrusive igneous rocks. Examples include granite, diorite, and gabbro. These rocks cool and solidify slowly, allowing large crystals to form.
What term describes igneous rocks that crystallize inside the Earth?
Intrusive igneous rocks.
What type of igneous rock that solidifies outside the crust?
extrusive igneous rocks, inside the earth is intrusive igneous rocks
