Most geologists think that the movement of earths plates caused by?
Geologists have hypothesized that the movement of tectonic plates is related to convection currents in the earth's mantle. Convection currents describe the rising, spread, and sinking of gas, liquid, or molten material caused by the application of heat.
Why do geologists think earth and core contains mostly iron?
Geologists believe that the Earth's core contains mostly iron due to seismic studies and the behavior of seismic waves, which suggest a dense, metallic inner core. Additionally, the high density of Earth’s core, estimated to be around 10-12 grams per cubic centimeter, aligns with the properties of iron and nickel, which are the most abundant elements in meteorites, thought to be representative of early Earth materials. Furthermore, the process of planetary differentiation likely caused heavier elements like iron to sink toward the center during Earth's formation.
Why do geologists think earths core contains most iron?
Geologists believe Earth's core contains most of the planet's iron due to the processes of planetary differentiation during its formation. As Earth developed from a molten state, heavier elements like iron sank toward the center, while lighter materials rose to form the mantle and crust. Seismic studies and the study of meteorites, which are thought to resemble early Earth materials, support the idea that iron is abundant in the core. Additionally, the core's density and magnetic properties align with the presence of a significant amount of iron.
Why do you think the iron at the earths core is partly liquid?
Heat and pressure.
Which two processes do scientists think move the earths lithospheric plates?
bruh
How do geologists think earths atmosphere formed?
how do geologists think earths atmosphere is formed
What element makes up of the earths core?
scientists think that the earths core is made up of mostly iron, and contains smaller amounts of copper nickel.
Why do you think geologists use drills bits covered with small diamonds to drill earths crusts?
Because they have to get through the minerals and rocks in the earths crust.
What do geologists think causes earths plates to move?
The movement of the Earth's plates is known as plate tectonics. Geologists think the plates move due to a build up of extreme heat in the Earth's crust.
What part of the earths system contains the air you breath?
I think it's the atmosphere

Why do you think that the work of geologists is important to our daily lives?
geologists affect our lives in the following ways. they monitor seismic activities within the earths interior and are able to warn us of impending earthquakes and impending shockwaves geologists monitor volcanoes and are able tom predict when the next eruption will occur and the expected magnitude geologists are also important in the process of drilling boreholes as they have crucial information on the type of soil found in different areas and they can offer crucial advice in the process of drilling bore holes geologists also moniter the earths magnetic fields and can use this fields to date rocks which can then tell us crucial movements of tectonic plates

What element makes up most of the earths core?
Iron is the primary element that makes up most of the Earth's core. It accounts for about 85% of the core's composition, with the rest likely being nickel in combination with some lighter elements.
What do you think earths atmosphere would be like today if life had not evolved on earth?
Almost no oxygen, lots of CO2, still mostly nitrogen.
What do geologists think creates earths magnetic field?
Geologists believe that Earth's magnetic field is generated by the movement of molten iron and nickel within the outer core of the planet. As these metals flow, they create electric currents that generate the magnetic field. This phenomenon is known as the geodynamo theory.
