Answer 1

6км потому-что 40-34=6

Answer 2

Calculation of the Thickness of Earth's Crust under the Sea

To calculate the thickness of the Earth's crust under the sea, we need to know that the thickness of the Earth's crust under land is 40 km, and it is 34 km less under the sea.

Let's denote the thickness of the Earth's crust under the sea as x.

According to the given information, we can set up the following equation:

40 km - 34 km = x

Simplifying the equation, we have:

6 km = x

Therefore, the thickness of the Earth's crust under the sea is 6 km.

Reverse Problems

Now, let's consider some reverse problems based on the given information.

1. Problem 1: The thickness of the Earth's crust under the land is 40 km, and it is 6 km under the sea. What is the difference in thickness between the land and the sea?

To find the difference in thickness, we subtract the thickness under the sea from the thickness under the land:

40 km - 6 km = 34 km

Therefore, the difference in thickness between the land and the sea is 34 km.

2. Problem 2: The thickness of the Earth's crust under the land is 40 km, and the difference in thickness between the land and the sea is 34 km. What is the thickness of the Earth's crust under the sea?

To find the thickness under the sea, we add the difference in thickness to the thickness under the land:

40 km + 34 km = 74 km

Therefore, the thickness of the Earth's crust under the sea is 74 km.
