What else can I help you with?
Why can't geologists use rocks from earth to learn how long ago earth formed?
Geologists can't use rocks from Earth to determine the planet's age because those rocks have all been recycled through the rock cycle over time. This means that the original rocks from when Earth formed no longer exist. Instead, geologists use radiometric dating of rocks from Earth's surface to estimate its age.
Does the Earth have Moon rocks?
Rocks were brought back to the Earth from the various Moon landings the Americans undertook. No other rocks from the Moon are on Earth. The Moon was formed from the Earth - so, if anything, there are Earth rocks on the Moon.
What type of rocks are formed from existing rocks that have been squeezed and heated up deep inside Earth's crust?
The type of rocks formed from existing rocks that have been squeezed and heated deep inside Earth's crust are called metamorphic rocks. This transformation occurs through a process known as metamorphism, which alters the mineral composition and structure of the original rocks, known as parent rocks. Common examples of metamorphic rocks include schist, gneiss, and marble.
Is magma the source of all rocks on earth?
No, while all rocks on Earth were molten at one point, most rock types do not form from magma. Rocks that form from magma or lava are igneous rocks. Most of the rocks at Earth's surface are sedimentary. These rocks form from the remains of rock that have been broken own into tiny pieces or dissolved in water. These components eventually settle, usually in a body of water, and are buried and turned to stone. Metamorphic rocks make up a third category. These form from rocks that have been altered under enormous heat and pressure while remaining solid.
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 can't geologist use rocks from earth to learn how long ago earth formed?
Because all of the rocks that were around when Earth formed have been recycled by plate tectonics and erosion. Hoped I helped!!

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.
How would present day animals and rocks on different continents compare since the continents have been separated for a long time?
Present day and animals and rocks on different continents compare the been separated for a long time by scientist examines rocks to find out about earth's history and structure
Where and when did toys first appear?
every since rocks came 2 earth along with mud pies

What were the first kind sof rocks on Earth's surface?
The initial rocks (apart from those direct from bolides) would have been volcanic rocks derived from the magma. This would have been in the late Hadean period of the Earth's history.

What pieces of other planets have been found on earth?
rocks
What was the gas in Earth's early atmosphere that was chemically converted or trapped in the rocks?
Oxygen was trapped in rocks in the very early days of earth. These rocks are known as "banded rocks". It took a long time before the oxygen was let out of the rocks.
How long has Earth been around?
Earth is estimated to be about 4.5 billion years old. Scientists have determined the age of the Earth through various methods, including radiometric dating of rocks and meteorites.
