There is no chart or problem or picture to work out here but a tenth would look like this 12.<u>3</u>9 .
Answer:
Heavy bombardment, solar wind, condensation, frost line, planetesimal, accretion, solar nebula, radiometric dating
Explanation:
The first few hundred million years of the solar system 19s history were the time of the <u>heavy bombardment</u>, during which Earth suffered many large impacts.
The era of planet formation ended when the remaining hydrogen and helium gas of the solar nebula was swept into interstellar space by the <u>solar wind</u>.
Ice can form from a gas through the process of <u>condensation</u>.
Hydrogen compounds in the solar system can condense into ices only beyond <u>frost line</u>.
Our Moon was most likely formed by a collision between Earth and a Mars-sized <u>planetesimal</u>.
Mars was formed by the <u>accretion</u> of smaller objects.
Our solar system was created by the gravitational collapse of the <u>solar nebula</u>.
<u>Radiometric dating</u> allows us to determine the age of a solid rock.
1. a. Lithosphere
If we divide the Earth into layers by their composition, then there are three of them, the crust, mantle, and core. The crust is the thinnest layer, being on the top, and being solid. The mantle is the second layer, lying between the crust and the core. It is a layer where the temperature and pressure are higher, and the rocks are hot and slow-moving. The core is the bottom layer, in the center of the planet. It is the hottest and has the highest pressure, being the densest of the layers and is composed mostly of iron and in lesser percentage of nickel.
2. b. Crust
The Earth is divided into several layers depending on the layers being solid or liquid. There are five different physical layers, lithosphere, asthenosphere, mesosphere, outer core and inner core. The lithosphere and the inner core are the two layers that are solid, thus the layer on top and the layer in the center. The asthenosphere, mesosphere, and outer core are all liquid, though it is a different degree of liquidity, and it is these three layers where the convection currents occur and cause the magnetic field of the Earth, as well as the tectonic movements.
Answer:
Factor that affect a country's deaths rate includes:
- Access to clean water
- Medical facilities
- Living standards of the people
Factor that could affect a country's birth rate include:
- Use of contraceptives methods
- Government Policies (The one child policy in China)
This is true, that Colombia is north of Brazil and in actual fact it is NW of Brazil. Colombia and Venezuela are both north of Brazil. Brazil is the largest country in Latin America and forms part of the BRIC countries ie Brazil Russia India China that have a large economic impact on the world.
