Why sedimentary rocks found as veneer?
Sedimentary rocks are often found as veneer because they are easily weathered and eroded, allowing them to be transported and deposited in various locations. Over time, these sediments can accumulate and form layers, creating a veneer of sedimentary rocks on the Earth's surface.
What are the kinds of earth rocks on earth?
The three main types of rocks on Earth are igneous, sedimentary, and metamorphic rocks. Igneous rocks are formed from the cooling and solidification of magma or lava. Sedimentary rocks are created from the accumulation and compaction of sediment particles. Metamorphic rocks are rocks that have undergone changes in temperature and pressure, often deep within the Earth's crust.
Why there are no sedimentery rocks on earth crust?
The Earth's crust does have sedimentary rocks in it's structure - limestone, slate, chalk, are three examples of commonly found sedimentary rocks.
Why would you not expect to find a metamorphic rock in the recesses of the earth?
You WOULD expect to find metamorphic rocks in the recesses (deep layers) of the Earth's crust. But not in the mantle or core. Metamorphic means changed - and rocks - either sedimentary or igneous - get changed by the heat and pressures found in the deep crust.
Rocks formed from weathered debris from preexisisting rocks are called?
They are called clastic sedimentary rocks.

What percentage of rocks on earth are sedimentary?
Approximately 75% of the rocks on Earth are sedimentary. This type of rock forms from the accumulation and compression of sediments over time. Sedimentary rocks are found in a wide range of environments, including oceans, rivers, and deserts.

Why sedimentary rocks could not have been the first rocks on earth?
Sedimentary rocks form from the accumulation of sediment such as sand, silt, or clay. For sedimentary rocks to form, there must be pre-existing rocks that weather and erode to produce sediment. Therefore, sedimentary rocks could not have been the first rocks on Earth as they require the presence of older rocks to form.
The orgin of sedimentary rocks?
Sedimentary rocks come from the deposition of material at the Earth's surface and within bodies of water.
Why would you not expect to find a metamorphic rock in the recesses of the earth?
You WOULD expect to find metamorphic rocks in the recesses (deep layers) of the Earth's crust. But not in the mantle or core. Metamorphic means changed - and rocks - either sedimentary or igneous - get changed by the heat and pressures found in the deep crust.
Do sedimentary rocks come from the center of the earth?
No. Sedimentary rocks form relatively close to the surface. No rocks that we have access to come from the planet's center.
How many rocks are ther in the word?
Three main typs metimorfic, igneous, and sedimentary
What percent of rocks on earth are sedimentary?
Approximately 75% of the rocks on Earth are sedimentary. These rocks form through the accumulation and compression of sediments over time due to processes like weathering, erosion, and deposition. Sedimentary rocks often contain valuable information about Earth's history and past environments.
What is the most common type of rock on earth's surface?
Sedimentary Rocks. 75% of rocks exposed to the surface are sedimentary.
How much of the Earth's outermost 10 miles is composed of sedimentary rocks?
Sedimentary rocks make up the majority of the Earth's outermost layer, known as the crust. The Earth's crust is approximately 25 miles thick, with sedimentary rocks accounting for about 75% of this layer. Therefore, roughly 7.5 miles of the Earth's outermost 10 miles is composed of sedimentary rocks.
