Answer:Periods of Earth's history with extensive sea ice result in enhanced albedo
Explanation:
Answer:
The true statement is that different gases with the same mass and temperature always have the same average kinetic energy. This is one of the postulates of the kinetic theory of matter.
If we two objects A and B, they will have mass mA and mB and velocity vA and vB respectively. If K.E = 1/2mv^2 . Then it follows that
1/2mAvA = 1/2mBvB. Since the mass is the same it means the velocity of the two objects should be the same so that they have the same average kinetic energy.
Over half of India's population works in agriculture, and monsoon rains directly affect their incomes and livelihood. Agriculture adds up to more than 15% of India's Gross Domestic Product (GDP), which means that when crops fail because of too little rain, the economy suffers.
Answer:

Explanation:
A subsistence farmer uses land in such a way that they only grow food and tends livestock to provide for a family.
They usually make use of crude tools such as basic gardening equipment to cultivate their portion.
- Subsistence farming does not require many farming technicalities.
- A farmer simply cultivates a piece of land and rare a limited number of animals for the need of himself and that of his family.
- Farming activities are generally less complex.
- It is not usually done for profit but to provide basic necessities for a small family.
So, a subsistence farmer uses the land to grow food and tend livestock to provide for a family.
