It is true, beacuse in China are living 1.357 billion people.
Answer:
1. Wind bounces and rolls sand along the ground, a process called saltation.
2. Sediment carried by the wind will drop to the ground when the wind's velocity decreases.
3. The force of the wind pushes particles up the windward slope of the dune as it moves.
4. The force of gravity allows particles to slide down the leeward slope of a dune as it moves.
Explanation:
Saltation is the process which involves the movement of the particles by the force of wind or water. The wind or the water removes the particles and carry them forward. Materials like pebbles and stones get carried away by the flow of water. The large particles get settled in the river bed.

The three types of unification that can alter political and economic relationship are Incorporating Federal (or con-federal) union and Mixed unions.
<u>Explanation:</u>
- A political union is a kind of state that is made of smaller states. The process of forming such a state out of smaller states is termed unification.
- The unification of states that used to be unified and that is reuniting is known as reunification.
- Types of unification that can alter political and economic relationships are as follows,
- Incorporating union
- Federal (or confederal) union
- Mixed unions.
Volcanoes can be two broad types: stratovolcano and a shield volcano namely.
In volcanology, viscosity plays a crucial role. High viscous (extremely sticky) magma eruptions typically result in steep-sided volcanoes with 30-35° slopes. This is due to the fact that the viscous volcanic material doesn't flow very far once it is erupted; instead, it accumulates in layers to form a cone-shaped volcano called a stratovolcano. In contrast, shield volcanoes have mild slopes of less than 10° and produce more basalt fluid lavas during eruption. A shield volcano's eruption can cause the basalt to flow far from the vent, creating broad, gentle slopes.
