Radda [10]
<h2>DNA Mutations</h2>

What property of water allows oceans to keep Earth's surface warm and insulated during
Scrat [10]

Answer:

This is the specific heat capacity

Explanation:

The specific  heat capacity of water is the quantity of heat energy needed to raise the temperature of 1 g of water by 1 degree.it is due to the  aggregation of hydrogen bonding  holding water molecules together.

Therefore,large quantity of heat energy is needed to be supplied to raise the temperature of water.

This is an advantage for earth temperature because  a significant rise in the earth temperature,would not  affect the earth because the ocean would have absorbed the heat.Therefore regulating the earth temperature within the narrow limits

However,during summer  little heat is released by the ocean and this cools the earth,this is because the specific heat capacity of the ocean is higher than that of the land,thus as the ocean warms up slowly its warms the earth.
