-
Crust
-
Mantle
-
Core
-
Oceans
Correct Answer
A. CoreExplanation
The core is the hottest layer of the Earth. It is composed of two parts, the outer core and the inner core. The outer core is made of liquid iron and nickel, while the inner core is a solid ball of iron and nickel. The temperature in the core can reach up to 5,500 degrees Celsius (9,932 degrees Fahrenheit). This extreme heat is due to the radioactive decay of elements and the residual heat from the formation of the Earth.Rate this question:

-
Wind
-
Water
-
Friction
-
Chemicals
Correct Answer
A. WaterExplanation
Water causes the most erosion on Earth because it has the ability to wear away and transport large amounts of sediment and rock. The force of moving water, such as rivers, streams, and ocean waves, can physically break down and carry away soil and rocks, shaping the Earth's surface over time. Water erosion is responsible for the formation of valleys, canyons, and other landforms, making it the primary agent of erosion on our planet.Rate this question:
