Aztec Level 3 Unit 9 Study Guide

1. Inner Core:

The inner core lays in the middle and is the warmest area of the earth. It is rock-hard and contains iron and nickel, with hotness of up to 5,500°c. It has a radius of approximately 1,220 km.

2. Core:

The core is the layer around the inner core. It’s a liquefied layer, which is also made up from iron and nickel. It’s exceptionally hot with temperatures equivalent to the inner core. Its outer boundary is around 2,890km beneath the earth’s surface.

3. The Mantle:

The mantle is the layer between the crust and the outer core, which is the broadest section of the Earth. It has a wideness of roughly 2,900. The mantle is made up of semi-molten rock called magma (lava). In the higher parts of the mantle the rock is stiff, but lower down the rock is delicate and starting

The Crust

It is a thin layer between 0-60 km thick. The crust is the dense rock layer it is the outside layer of the Earth, there are two types which are called oceanic and continental.

Task 2 Part 2: Panspermia is the theory that life exists throughout the Universe, distributed by planetoids, asteroids and meteoroids. Bacteria may travel for a lengthy amount of time before crashing randomly with other planets or disks. If met with ideal conditions on a new planets’ surfaces, the bacteria becomes active and the process of evolution begins.

In natural science, abiogenesis is the natural process by which life arises from non-living matter, such as simple organic compounds. It is a study of how biological life processes, and the method by how life on how Earth arose.

The idea of catastrophism or “consecutive creations”, is the theory that changes earth’s crust geological history from sudden violent and unusual events. Catastrophism is the idea that Earth has been affected in the past by sudden, short-lived, violent events, possibly worldwide in space. This view holds that the present is the key to the past, and that all things continue as they were from the beginning of the
