Review - Unit 1 AOS 1 Chapter 2 Earth systems thinking

The natural interactions between Earth's four systems: the atmosphere, biosphere, hydrosphere, and lithosphere, support and are affected by the movement of energy and matter within and between local and global ecosystems. Which of the following best describes these interactions?

• They operate independently without affecting each other.

• They are interconnected and influence each other.

• They only interact during natural disasters.

• They are solely dependent on human activities.

What is systems thinking in the context of environmental systems?

• Identifying inputs and outputs

• Exploring relationships

• Representation of local systems

• All of the above.

The biosphere is best described as:

• the global sum of all ecosystems.

• a single ecosystem in a specific region.

• the atmosphere surrounding the Earth.

• the water bodies on Earth.

The hydrosphere includes all water on Earth. What role does groundwater play in the hydrosphere?

• It is a major source of freshwater for human use.

• It is primarily found in oceans and seas.

• It is not part of the hydrosphere.

• It only exists in the form of ice.

The lithosphere is best described as:

• the rigid outer layer of the Earth, consisting of the crust and upper mantle

• the liquid layer of the Earth's core

• the gaseous layer surrounding the Earth

• the innermost layer of the Earth

Which of the following describes the properties of several soil types?

• Sandy soil is gritty and drains quickly, clay soil is sticky and retains water, and loamy soil is a mix of sand, silt, and clay.

• Sandy soil is sticky and retains water, clay soil is gritty and drains quickly, and loamy soil is only made of clay.

• Sandy soil is a mix of sand, silt, and clay, clay soil is gritty and drains quickly, and loamy soil is sticky and retains water.

• Sandy soil is only made of clay, clay soil is a mix of sand, silt, and clay, and loamy soil is gritty and drains quickly.

The atmosphere is composed of several layers. Which of the following is the correct order of these layers from the Earth's surface upwards?

• Troposphere, Stratosphere, Mesosphere, Thermosphere, Exosphere

• Stratosphere, Troposphere, Mesosphere, Thermosphere, Exosphere

• Mesosphere, Troposphere, Stratosphere, Thermosphere, Exosphere

• Exosphere, Thermosphere, Mesosphere, Stratosphere, Troposphere

The four spheres interact in various ways. Which of the following is an example of such interaction?

• The atmosphere provides oxygen for animals to breathe.

• The hydrosphere is completely independent of the biosphere.

• The geosphere does not affect the atmosphere.

• The biosphere and hydrosphere do not interact.

What forms the biosphere?

Where are all organisms on Earth found?

• Biosphere

• Atmosphere

• Lithosphere

• Hydrosphere
