السؤال 1

In an experiment where a covered cup of water is placed in the sun, what process is primarily observed inside the cup that mimics a part of the water cycle?

Precipitation and runoff

Only condensation

Only evaporation

Evaporation followed by condensation

السؤال 2

Igneous rocks are fundamentally formed from what material?

Magma or lava

Existing rocks transformed by heat and pressure

Compacted sediments

Organic remains

السؤال 3

What does the rock cycle describe?

The process of fossil fuel formation over millions of years.

The daily changes in rock appearance due to weather.

The movement of tectonic plates causing earthquakes.

The transformation of rocks from one type to another through various Earth processes.

السؤال 4

Which statement accurately differentiates weathering from erosion?

Weathering involves chemical changes, while erosion involves physical changes only.

Weathering forms new rocks, while erosion melts old ones.

Weathering breaks down rocks, while erosion transports the broken fragments.

Weathering occurs only on the surface, while erosion occurs underground.

السؤال 5

Liquid water can turn into water vapor only when it reaches its boiling point.

False

True

السؤال 6

Marine microorganisms are the primary organic origin for both coal and petroleum oil.

True

False

السؤال 7

What is the primary characteristic of the water cycle?

It only involves the transformation of water within the Earth's surface.

It is an open system that continuously loses water to space.

It exclusively moves water from Earth to the atmosphere.

It is a closed, multi-path process involving water movement between the atmosphere and Earth.

السؤال 8

What are the three natural states in which water exists?

Freshwater, saltwater, and groundwater.

Solid, liquid, and gas.

Ice, vapor, and mist.

Rain, snow, and hail.

السؤال 9

Which of the following is an example of a plutonic igneous rock with large crystals?

Basalt

Pumice

Marble

Granite

السؤال 10

Which type of igneous rock is characterized by large crystals and forms from magma solidifying slowly within the Earth's crust?

السؤال 11

Which of the following is a distinguishing characteristic of sedimentary rocks?

They form from quickly cooled lava on the Earth's surface.

They are formed deep within the Earth under intense pressure and heat, without melting.

They are often porous and may contain fossils.

They always have large, interlocking crystals.

السؤال 12

Which statement accurately defines weathering?

The process of transporting rock fragments away from their original location

The process of sediments being deposited in new areas

The process of breaking and fragmenting rocks

The process of magma solidifying within the Earth's crust

السؤال 13

A conceptual or physical model of the water cycle is useful for what primary purpose?

To stop natural water flow in rivers.

To illustrate the mutual relationship between system components and their environmental impacts.
