What is the composition of the crust under the continents How do you know?
The crust under continents is primarily composed of granitic rocks, which are rich in silica and aluminum. We know this through studies of rock samples collected from the Earth's surface and seismic data that provide information about the composition and structure of the crust beneath continents. Additionally, drilling projects such as the Mohole project have allowed for direct observations of crustal composition at depth.
What do we know about what it looks like beneath the earth's crust?
You will never know what it look like under the earth's crust :)
What is a good sentence for continental drift?
The term 'continental crust' is a compound noun, a word for therelatively thick part of the earth's crust that forms the large landmasses. A noun functions in a sentence as the subject of a sentence or a clause, and as the object of a verb or a preposition. Examples:Bobby has no idea what a continental crust is. I explained to him that continental crust is land (territory).
What are the two kinds of crust?
Earths crust is the outer shell of our planet. The Earth has two types of crust. Continental crust contains igneous, sedimentary and metamorphic rocks that covers the continents. Oceanic crust contains igneous basalt rocks derived from the upper mantle that cover the all the ocean floors. The igneous rocks are covered with sediments carried into the oceans from large rivers like the Amazon and Mississippi Rivers.
What does a seismic reading do under the ocean?
A seismic reading under the ocean helps scientists to map the structure and composition of the Earth's crust beneath the seafloor. By analyzing the data from seismic readings, researchers can better understand tectonic plate movements, seismic activity, and the formation of underwater features like rifts and ridges.
What is the composition of the crust under the continents How do we know?
The composition of the crust under continents consists mainly of granitic rocks (continental crust). We know this through seismic studies that measure the speed of seismic waves traveling through the crust, density measurements, and rock samples brought up from drilling and mountain-building processes.

I know there is water under land But what is under water?
If we look beneath water, no matter how deep, we will always find the rock of the crust of the earth. You might have heard the term "ball of rock" applied to the earth, and the crust is the outer covering of that ball of rock. All of the world's oceans sit on top of the crust of the earth.
Why did the Continents breakup?
The breakup of the continents was primarily caused by the movement of tectonic plates in the Earth's crust. This movement led to the gradual separation of landmasses over millions of years, creating the continents as we know them today. This process is known as plate tectonics.
What are the most common elements in the Earth's crust?
One is silicon, but I don't know the other:(oxygen
What do the continents lie on?
My year 7 Geography teacher told mt that under the continents there is a substance like a soild-liquid. It is soild under preaseure and it the preasure is released then it turns to a liquid.I don't know for sure, because I am twelve, but I would think that currently this solid-liquid would be a soilid because the average specific gravity of continents is 2.7 and once a gain, I don't know if that is heavy and putting alot of preassure on this solid-liquid or not.
What is a pangaea plate?
Pangaea was a supercontinent that existed about 300 million years ago, when all the Earth's continents were joined together as a single landmass. The plates that make up the Earth's crust shifted over time, breaking apart Pangaea into the continents we know today.
What do scientists study to learn about the temperature inside the earths crust?
Scientists study seismic waves to learn about the temperature inside the Earth's crust. By analyzing the speed and direction of these waves as they travel through different layers of the Earth, scientists can infer information about the temperature and composition of the Earth's crust.
Pangea and continental drift?
Pangaea was a supercontinent that existed about 300 million years ago and eventually fragmented into the continents we know today due to the process of continental drift. Continental drift is the theory that suggests the Earth's continents move slowly over time due to the motion of tectonic plates in the Earth's crust. This movement has caused the continents to drift apart, leading to the formation of the current continental configuration.
What purpose do continents serve?
Because with out continents the government had know way to keep us in line.
