Basically, Earth can divide into 4 layers, Earth crust, mantle, outer core and inter core.

Earth crust is the outermost solid shell of the Earth.

The crust has a variable thickness, being 35-70 km thick in the continents and 5-10 km thick in the ocean basins. The temperature is lowest among the layers of the Earth and the most suitable for living things.

Mantle is the interior of the Earth. It is about 2900 km thick. The mantle is a highly viscous layer directly under the crust, and above the outer core. The temperature is around 2000 °C–4000 °C.

The outer core is 2300 km thick and the inner core is 1200 km thick. The outer core is composed mainly of a nickel-iron alloy, while the inner core is almost entirely composed of iron. The temperature is very high, more than 4000 °C

地球的内部可以分为三层，地壳、地幔和地核。而地核则可以分为内核和外核。地球的每一层都具有不同的温度及压力。地层越深，温度和压力就越高。地球的最外层是地壳，温度最低，也是最适合生物生存。地幔是地球的中层，也就是位于地壳和地核之间。最内层的是地核，外核和内核。

Standard 6 六年级, Force 力、移动

Forces cannot be seen but their effects can be observed. A force can change the shape of an object, cause different effects on stationary and moving objects. Friction, is a force that opposes the movement of an object.

This question is to examine the student understanding of the effect of forces and friction. Forces and friction can affect the distance travelled of the toy cars.

1) the force applied -- During the experiment, if the forces applied on both toy cars are different, the distance travelled will be different. The higher a force is applied, the further it travelled.

2) the weight of the toy car -- The mass of the object can cause friction and affect the distance travelled of the toy car. The heavier the toy car, the greater the frictional force, and the distance travelled will be shorter.

3) the size of the toy car -- The size of the surface can also affect the frictional force. The smaller the toy car, the lesser the frictional force, and the distance travelled will be further.

If we changed the surface of the ramp or the angle of the inclined ramp, it will affect the results of the experiment. However, the logics behind are still the same.

力，是我们看不到，但可以观察到它的效应。力可以改变物体的形状、位置和速度。而摩擦力乃是一股力量让物体移动变得艰难，会把物体拖回去的感觉。

这个题目是在考学生对力及摩擦力的了解。力和摩擦力都可以影响到玩具车移动的距离不相同。

（一）推力的力度 -- 当我们对实验中的两辆玩具汽车所施的力度不一样时，玩具车移动的距离就会不相同。推力越大，移动越远。

（二）玩具气车的重量 -- 由于重量会产生摩擦力，因而改变玩具车移动的速度与距离。玩具汽车越重，产生的摩擦力就越大，移动的距离会越短。

（三）玩具汽车的体型 -- 此外，物体的形状也会影响摩擦力的强度。体积越小，摩擦力也越小，移动会越远。

如果我们把现有的斜面的粗滑程度改变或把斜面的高度调整，试验的成果也会有所改变，但是原理还是一样。
