it has to be left by a glacier and it's basically all sediment

Scientists determine if a deposit of rocks is till rock by examining its composition, texture, and characteristics such as unsorted grains, angular shapes, and presence of clay. Till rocks typically have a heterogeneous mixture of rock fragments that show evidence of glacial transport and deposition. Analysis of the sediments and landforms surrounding the deposit can also provide clues to its origin.

Do isotopes enable scientist to determine th size or age of some rocks?
Isotopes can be used in radiometric dating to determine the age of rocks. By measuring the ratio of parent and daughter isotopes in a rock sample, scientists can calculate how long it has been since the rock formed. This method is particularly useful in dating rocks that are billions of years old.
How can you determine accurate ages of rock layers?
Stratigraphic position Age Dating techniques i.e. carbon etc Fossil Assemblage present in rock specimen
How do fossils in rock layers help scientists identify the age of rocks?
Fossils in rock layers can be used for relative dating, where older fossils are found in lower layers and younger fossils in higher layers. By comparing the fossils in different layers to known fossil sequences, scientists can estimate the age of the rocks. Fossils provide a timeline of life on Earth and can help determine the relative ages of rock layers.
What factors determine how fast rocks will weather?
what is a elementary rock
Scientists study rocks using what important criteria?
Scientists study rocks based on their mineral composition, texture, structure, and formation process. These criteria help scientists understand the history of the rock, its properties, and the environmental conditions that existed when the rock was formed.
How do scientists use to determine the age of a rock on the ocean floor?
Scientists use a method called radiometric dating to determine the age of rocks on the ocean floor. This technique involves measuring the proportions of certain radioactive isotopes and their decay products within the rock to calculate how long it has been since the rock formed. By analyzing these ratios, scientists can estimate the age of the rock.
What is the law of superposition and how does it help scientists learn about earth's past?
The law of superposition states that in a sequence of undisturbed rock layers, the oldest layers are at the bottom and the youngest layers are at the top. By studying the order of rock layers and the fossils within them, scientists can determine the relative ages of the rocks and reconstruct the Earth's past environments and history.
What is the geologic law that scientists use to date the crust by studying the layers of rocks called?
The geologic law that scientists use to date the crust by studying the layers of rocks is the Law of Superposition. This law states that in a sequence of undisturbed rock layers, the oldest rock layer will be at the bottom and the youngest will be at the top. By studying the relative positions of these rock layers, scientists can determine the relative ages of the rocks.
What process involves the comparison of rock layers with others in a sequence to determine its age?
Relative dating involves comparing rock layers with others in a sequence to determine their ages. This process relies on the principle of superposition, where younger rocks are usually found on top of older rocks. By studying the relationships between different rock layers, scientists can establish the relative ages of the rocks.
How scientist know the age of a rock?
Scientists use radiometric dating to determine the age of rocks by measuring the decay of radioactive isotopes in the rock. This method relies on the known rates of decay of specific isotopes to calculate the age of the rock. By analyzing the ratio of parent isotopes to daughter isotopes in a sample, scientists can accurately determine how long ago the rock formed.
How do scientists use the rate at which radioactive elements decay in rocks?
Scientists use the rate at which radioactive elements decay in rocks to determine the age of the rocks. By measuring the ratio of parent and daughter isotopes in a rock sample, they can calculate how long it has been since the rock formed. This method is known as radiometric dating and is commonly used to determine the age of rocks and artifacts.
Do isotopes enable scientist to determine th size or age of some rocks?
Isotopes can be used in radiometric dating to determine the age of rocks. By measuring the ratio of parent and daughter isotopes in a rock sample, scientists can calculate how long it has been since the rock formed. This method is particularly useful in dating rocks that are billions of years old.
True or False To find the specific age of rocks scientist cannot use radiometric dating?
False. Radiometric dating is a common method used by scientists to determine the age of rocks. By measuring the ratio of radioactive isotopes to stable isotopes in a rock sample, scientists can calculate how long ago the rock formed.
What is special about a sedimentary rock?
Nothing. Scientists have reached consensus that there is absolutely nothing important or special about sedimentary rock. Sedimentary rocks are barely even rocks. Some scientists are pushing to have sedimentary rocks declassified as rocks, and reclassified as extraneous matter.
How do scientist age a rock?
Scientists age rocks using various methods, such as radiometric dating which measures the decay of radioactive isotopes within the rock, or by studying the layers of rock and fossils found within to determine its relative age based on the principle of superposition. These methods help scientists determine the age of the rock and gain insight into Earth's history and past geological events.

Are physical and chemical properties of rocks helpful to determine the type of rock?
They are the only way to determine a rock type.
