What are the 2 characteristics of sedimentary rocks that reveal the past history of the earth?
Presence of fossils and stratification of the rocks structure into different layers.
Does harry find anything else about Dumbledores past?
That depends on which book you're on. You learn alot about Dumbledore in the 7th book.
Why are there lots of sedimentary rocks found at the Grand Canyon?
The plateau through which the Colorado river has incised the Grand Canyon was, for the majority of the past 500 million years, below sea level and therefore an area upon which sediments have accumulated for a long time. The uplift of the plateau is, geologically, relatively recent and the Canyon guts its way down through this thick sedimentary stack.
How are sedemintary rocks formed?
Sedimentary rocks are formed by sand and dirt , but mostly sand, it gets wet, by years of water, and later on, past long periods of time, you'll have rock but, it's still is very soft
How do you get past the rats in south park?
There are many rats, but I assume you mean the ones blocking access to the woods around town. You can blow them away when you learn 'Dragonshout', the default key for it is 'G'.
How can sedimentary rocks helpus learn about earths's past?
it is good
How are sedimentary rock layers used by scientists to learn about the past?
Scientists can study sedimentary rock layers to interpret past environments, climate conditions, and geological events. By examining the composition, thickness, and arrangement of these layers, they can determine the history of sediment deposition and identify past changes in Earth's surface. Fossils found within the rock layers also provide valuable information about past life forms and ecosystems.
What type of rock is most useful historical geologists?
Sedimentary rocks are most useful for historical geologists because they can contain fossils and provide information about past environments and the Earth's history. Sedimentary rocks also often preserve layers that can be used to determine the relative age of rock formations.
How can geologists infer from sedimentary rocks what the surface conditions of Earth's past were like?
Geologists can infer past surface conditions from sedimentary rocks by examining the sediments' composition, characteristics, and structures, such as ripple marks and cross-bedding. Fossil content can also provide clues about past environments, like the presence of marine organisms indicating a shallow sea. By studying these aspects, geologists can reconstruct a picture of Earth's past climate, landscapes, and ecosystems.
How are sedimentary rock used by scientists to learn about the past?
Sedimentary rock layers are used by scientist help learn by the texture and shapes
How do geologists learn about how the block of rock along a fault move?
They map the earthquakes intensity and where the past earthquakes were.
How are sedimentary rock layers used be scientists to learn about the past?
plant and animal fossils are most often found in layers of sedimentary rocks
What can geologist learn from fossils?
Geologists can learn about the Earth's history, past environments, and changes in climate by studying fossils. Fossils provide evidence of how life has evolved over time and can help geologists understand the geological processes that have shaped the planet. They also help in dating rocks and determining the age of different geological formations.
What can geologists learn about the interior of Earth from rock samples?
Because is gives evidence for the Scientists that want to know more about the past. :)
Sedimentary rocks are useful as records of past time because of?
their layered structure that forms over time, preserving a record of environmental conditions and events that occurred in the past. Sedimentary rocks can contain fossils that provide clues about past life forms and the history of Earth's ecosystems. Additionally, the mineral composition of sedimentary rocks can help geologists determine the age and origin of the rock layers.
Geologists learn what organisms were like in the past by studying?
fossils found in rocks and sediment layers. By examining the structure and composition of these fossils, geologists can infer information about the ancient organisms, such as their appearance, behavior, and evolutionary relationships. This helps build a picture of past environments and ecosystems.
Sedimentary rocks record past geological events and what else?
Sedimentary rocks also provide insights into past environmental conditions, such as climate, the presence of water, and the types of organisms that may have lived in that area. Additionally, they can contain important resources such as fossil fuels, minerals, and groundwater.
