Describe是一種MySQL（關係型資料庫管理系統）的一種命令，用於描述指定數據表的結構。
基本介紹
- 中文名：描述
- 外文名：Describe
Describe the major parts of the Earth.
If you journeyed to the center of the Earth, What do you think you would see along the way?
Crust
The thinnest most outer layer of the Earth
It is composed of.
Oxygen
Irons
Potassium
Calcium
Sodium
Silicon
7Aluminum
Magnesium
9 Made up of 3 types of solid rocks.
10 Igneous: Hot liquid, rocks deep with in the Earth, that cools and hardens as it reaches the surface.
11 Sedimentary: When sediments (small places of rocks, sound, other materials) are pressed and cemented together by the weight of layers that build up over time.
Metamorphic
13 Igneous and sedimentary rocks are changed by hear pressure. Other chemicals
14 The Earth's crust forms the upper part of the lithosphere.
Lithosphere ranges from 50 to 100KM thick.
16 The crust depth extends 8 to 3KM.
What is the Earth is crust?
Where is the mantle located?
How far does it extends below the Earth is surface?
Earth crust: BE the hull layer that the Earth hard surface arrives an of the noodles of to constitute to from each kind of rock as follows, at big land average thickness 35 kames, under the ocean equally thick 5kms. Earth crust thickness the difference is very big. The earth crust constitutes to from the deposition hull, layer and the martial quality hull layer of the flower quality hull. The earth crust means the rigid outer shell of the Earth surface belong to the upper part of lithosphere. Constituting of earth crust can from the chemical element, mineral, rock three aspects to explain.
Describe Earth's major parts.
Mantle
1 The layer of the Earth directly above the core.
2 Extends to a depth of 2900KM below the Surface.
3 About 80% of the volume of the Earth and 68% of the plant's mass are in the mantle.
4 Composed mostly of:
Irons
Magnesium
Silicon
Oxygen
Density increases with depth because of the in the lower part of the mantle.
The temp and pressure increases as you go deeper into the Earth.
Temperance from 870/c =1,598/F in the lower mantle.
Both layers of the Earth's core are made up of iron and nickel.
Temperance of the inner core reaches 5,000/C =9,032/F.
Inner core is solid.
Depth of the inner core is about 5150KM.
Surrounding the inner core is the outer core.
Begins about 2900KM below the surface and about 2,250KM thick. Also made up of iron and nickel. Temperance from 2200/C to 5000/C.
描述地球的大部分。
披風
1地球的層數直接地上面核心。
2延伸到深度的2900KM在表面之下。
3大約80%地球的容量和68%植物的大量在披風。
4組成了主要：
鐵
鎂
矽
氧氣
密度增量與深度由於在披風的低部。
臨時雇員和壓力增量，你去深入地球。
節制從870/c =1,598/F在下地幔。
地核的兩層數由鐵和鎳製成。
核心的節制到達5,000/C =9,032/F。
核心是堅實的。
核心的深度約為5150KM。
圍攏核心是外面核心。
在表面之下開始大約2900KM和大約2,250KM厚實。
並且組成鐵和鎳。
節制從2200/C到5000/C。

Temp ranges from 870/c =1,598/F in the lower mantle.
