They are bounded by the Olympic Mountains to the north and the Columbia River. Doty Hills, and the adjacent broad valleys that open up to the Pacific Ocean
Answer:
A. Sedimentary rocks of Precambrian age
Explanation:
As most of the sedimentary rocks contain mineral deposits like shale, quads, calcite. Amongst all major types of rocks sedimentary rock are commonly known for fossil deposits and fossil in the end consist of a thin layer of carbon the process is known as Carbonisation and is responsible for formation of fuels and coal etc.
The first person to calculate the circumference of the Earth and coined the word "geography" was Eratosthenes. The man who successfully applied his scientific research to create an illustration of the first world map was Anaximander. The person who invented the globe and argued that the representation of the world as a flat, two-dimensional object was not accurate was Ptolemy. He developed the science of geography, although he was better known for his contributions to mathematics was Eratosthenes. The Greek-derived word "geography" means to describe the Earth is correct. China's greatest contribution to geography was the compass. This allowed you to find out which direction you were going extremely easy. The earliest world map ever found was carved on a Babylonian clay tablet that showed Earth as a flat, circular disk, this is correct. It was believed to be created in 6th century BCE. Ptolemy incorporated topography into his maps, which means that the mountain and valley surfaces would appear on the map. This is correct and is the birth or starting of the topological maps! This early group, the Greeks, were the first to use rational thought or logic while investigating the physical world. It is believed that the science of geography originated with each of the following groups except the British. The British are believed to have no contributions to the science of Geography.
Answer:
Beyond the <u>Atmospheres</u> that surrounds Earth, there are seven other planets. All planets in our <u>Solar system</u> revolve, or make <u>rotation </u>around the sun. All the planets get <u>energy </u>from the sun. The <u>features </u>of planets differ in some ways. For example, the <u>surface </u>of Mars is <u>solid </u>and rocky, but Saturn is gaseous. There are also differences in size, or <u>measurement </u>.

Answer:
Regardless of its name, the Big Bang theory found widespread acceptance for its unparalleled ability to explain what we see. The balance of light with particles like protons and neutrons during the first 3 minutes, for instance, let early elements form at a rate predicting the current amounts of helium and other light atoms.
"There was a small window in time where it was possible for nuclei to form," said Glennys Farrar, a cosmologist at New York University. "After that, the universe kept expanding and they couldn't find each other, and before [the window] it was too hot."
A cloudy plasma filled the universe for the next 378,000 years, until further cooling let electrons and protons form neutral hydrogen atoms, and the fog cleared. The light emitted during this process, which has since stretched into microwaves, is the earliest known object researchers can study directly. Known as the cosmic microwave background (CMB) radiation, many researchers consider it the strongest evidence for the Big Bang.
