Geologists have divided earths history in the manaeable units that are represented by the?

Geologists have divided Earth's history into manageable units called eons, eras, periods, and epochs. These divisions help scientists study and understand the Earth's geological and biological history over millions of years.


How is time measured of earth?

Time on Earth is measured using different units such as seconds, minutes, hours, days, weeks, months, and years. It is based on the Earth's rotation around its axis (day and night cycle) and its orbit around the Sun (changing of seasons). The most common unit for measuring time on Earth is the Gregorian calendar, which is a solar calendar based on the time it takes for Earth to complete one orbit around the Sun (365.24 days).


What is the major natural force shaping the landscape over most of the Earth?

The major natural force shaping Earth's landscape is erosion, caused by factors such as water, wind, and ice. Erosion slowly wears down rocks and landforms, reshaping the Earth's surface over time.


What is the major agent of erosin on Earth' surface?

Water is the major agent of erosion on Earth's surface. It can wear away rock and soil through processes like rainfall, rivers, and waves. Water erosion shapes the landscape by carrying sediment and reshaping landforms over time.


What are the three main layers of earth based on composition?

Physically, the Earth has numerous layers. Chemically, however, the solid portion of Earth can be divided into three distinct layers. In order from the surface going down, they are as follows: 1. The Crust--Major chemical constituents are oxygen, silicon, and aluminum. 2. The Mantle--Major chemical constituents are silicon, oxygen, iron, and magnesium. 3. The Core--Mostly iron and nickel.

You don't convert units of length to units of time; those two are utterly incompatible.If an object moves at a certain speed, you can use the formula distance = speed x time, to relate the three. If you know two of these three pieces of information, you can calculate the third.You don't convert units of length to units of time; those two are utterly incompatible.If an object moves at a certain speed, you can use the formula distance = speed x time, to relate the three.
