true
false

Explanation:

Identify the sphere covering 70% of Earth's surface

The hydrosphere represents all water on Earth, which covers approximately 70% of the planet's surface.

Define cultural diffusion

Cultural diffusion is defined as the spread of cultural beliefs, practices, and knowledge from one group of people to another.

Identify the natural landform joining two continents

An isthmus is a narrow strip of land connecting two larger landmasses. The Isthmus of Panama naturally connects North and South America. (The Suez Canal is man-made, and the Sinai Peninsula is a peninsula rather than a narrow connecting strip).

Evaluate the accuracy of the equator on a cylindrical projection

On a standard cylindrical projection (like the Mercator projection), the cylinder is tangent to the globe at the equator, meaning there is zero distortion along the equator, representing it most accurately.
