The deepest layer of the Sun that we can directly observe is called the photosphere. It extends to around 250 miles (400 km) above the visible surface at the core of the solar disk.
A layer in the Sun between about 250 miles (400 km) and 1300 miles (2100 km) above the solar surface is known as the chromosphere (the photosphere). The chromosphere's temperature ranges from about 4000 K at the bottom (the so-called minimum) to 8000 K at the top (6700 and 14,000 degrees F, 3700 and 7700 degrees C). As a result, in this layer (and higher layers), the temperature increases as you move further away from the Sun, as opposed to the lower layers, where the temperature increases as you move closer to the Sun's center.
Transition Region: Between the chromosphere and the corona, there is a quite small layer (60 miles/100 km) where temperatures suddenly increase from 8,000 to 500,000 K. (14,000 to 900,000 degrees F, 7700 to 500,000 degrees C).
The Sun's corona, which begins at around 1300 miles (2100 km) above its surface, is its outermost layer (the photosphere). The corona has a temperature of 500,000 K (900,000 F, 500,000 C) or higher, possibly up to a few million K.

geologists can investigate the interior of earth by ______.
Answer:
To study Earth's interior, geologists also use an indirect method. But instead of knocking on walls, they use seismic waves. When earthquakes occur they produce seismic waves. Geologists record the seismic waves and study how they travel through Earth.
Explanation:
Geologists also employ an indirect approach to research the innards of the Earth. But they employ seismic waves rather than banging on walls. Seismic waves are created by earthquakes. Geologists observe and record seismic waves as they move through the Earth.
What is Geologists?an expert in the examination and study of geology. Geologists and geophysicists study the composition, structure, and other physical features of the earth. As a geologist or geophysicist, you might work on initiatives to identify and offer guidance on the extraction of minerals, petroleum, and ground water.
Geologists are researchers who focus on the composition, history, and dynamics of the Earth. Geologists come in a wide variety of specialties; two examples are environmental geologists, who study how people interact with the environment, and economic geologists, who look for and use the planet's natural resources.
This includes almost all earthly features, including volcanoes, earthquakes, rocks, mountains, and oceans. The discipline of historical geology focuses on the past of the planet.

a. Some sediment is brought to glaciers by streams
b. Sediment that is carried and deposited by a glacier is a moraine
c. The sides and base of glaciers have the most abundant sediment
d. Sediment is largely unsorted and angular
By releasing less moisture into the sky, cold ocean currents can stop the formation of glaciers, and stronger ocean currents can bring colder water to the surface, which cools the land. The impact of continental drift on glaciers, ocean currents, and the overall climate is accurately described by this phrase.
Due to the fact that melting glaciers hold their water on land, runoff significantly increases the amount of water in the ocean, raising the sea level.
When the climate changes, glaciers, and ice caps react to the changes in the atmosphere and the ocean, which also clearly indicates that the climate is changing globally. Important information about the past temperature of the planet may also be found in glaciers, especially the vast inland ice caps.

Upon burial, the sediment loses moisture and is cemented into rock.Rocks larger than small particles of clay are called sediments and are moved by water. Fast-moving water can pick up, suspend, and displace larger particles than slow-moving water. High concentrations of suspended sediment can displace vegetation, invertebrates and insects in riverbeds. This can affect the fish's food sources, resulting in smaller and fewer fish. Sediment can bury and suffocate fish eggs.
