Water, evaporating from the surface of a lake, is an example of water moving from the -

• hydrosphere to the atmosphere.

• geosphere to the hydrosphere.

• atmosphere to the hydrosphere.

• atmosphere to the geosphere.

Answer explanation

Water evaporating from a lake moves from the hydrosphere (water bodies) to the atmosphere (air). This process illustrates the transition of water from one sphere to another, confirming the correct choice.

When living things breathe, which of Earth's spheres are interacting?

• geosphere and hydrosphere

• atmosphere and biosphere

• geosphere and biosphere

• biosphere and hydrosphere

Answer explanation

When living things breathe, they exchange gases with the atmosphere, which is part of the biosphere. Thus, the correct interaction is between the atmosphere and biosphere.

Oceans, rivers, lakes, and the moisture in the air are all components of which of Earth's spheres?

• Hydrosphere

• Biosphere

• Atmosphere

• Geosphere

Answer explanation

The hydrosphere encompasses all water components on Earth, including oceans, rivers, lakes, and atmospheric moisture. Therefore, the correct answer is the hydrosphere.

An atom of which element is described by the data in the table?

• Hydrogen (H)

• Potassium (K)

• Calcium (Ca)

• Yttrium (Y)

Answer explanation

The data likely indicates atomic number and mass. Potassium (K) has an atomic number of 19, which matches the data, while Hydrogen (H), Calcium (Ca), and Yttrium (Y) do not fit the criteria.

A model of a beryllium atom is shown below. What types of particles are found in the cloud surrounding the atom’s nucleus?

• Positively charged particles and negatively charged particles

• Negatively charged particles only

• Neutral particles and positively charged particles

• Positively charged particles only

Answer explanation

In a beryllium atom, the cloud surrounding the nucleus contains negatively charged particles, known as electrons. Therefore, the correct answer is 'Negatively charged particles only'.

Which state of matter is being described by the table?

Answer explanation

The table likely describes properties such as fluidity and shape, which are characteristic of liquids. Liquids have a definite volume but take the shape of their container, distinguishing them from solids and gases.

Study the spacing and arrangement of the particles the sample to identify what is represented. Which terms best complete the sentence? Sample 1 is a __________ because the particles move freely.

• Solid

• Liquid

• Gas

Answer explanation

Sample 1 is a gas because its particles move freely and are spaced far apart, unlike solids and liquids where particles are closely packed and have limited movement.

Study the spacing and arrangement of the particles the sample to identify what is represented. Which terms best complete the sentence? Sample 2 is a __________ because the particles are rigid.

• Solid

• Liquid

• Gas

Answer explanation

Sample 2 is a solid because its particles are closely packed and rigid, allowing them to maintain a fixed shape. In contrast, liquids and gases have more spaced-out particles that can move freely.
